Acanthopanaz spinosum does not occur in China; what has been con- sidered to be that species represents the following two distinct species.

1, Acanthopanax Hondae Matsuda in Tokyo Bot. Mag. xxx1. 333 (1917).

Differt ab Acanthopanace koreano quo valde affine, umbellis breviradiatis, floribus minoribus, foliis grossius serrulatis. Hoc etiam Acanthopanacem villosulum accedit sed foliis subtus non villosis disco viride exquo distinctum.

The cohesion of the styles varies specifically but it is of no value in the classification of sections. The characters distinguishing Eleutherococcus from Acanthopanax are neither the cohesiveness of styles nor the presence of articulation in the flowers. No species of Acanthopanax or Eleuthero- coccus has real articulation at the base of the calyx. The seeming arti- culation appears in the dried specimens by the contraction of tissues at the base of the calyx. That portion of calyx differs in texture from the apices of the pedicels. The apices of pedicels have hard vascular bundles and do not shrink as much when dried as does the base of the calyx which consists of soft parenchyma. This non-uniform shrinking causes a false articulation. Nearly all of the species belonging to genera other than the Aralia group have with few exceptions inarticulated flowers. Eleuthero- coccus differs from Acanthopanax by the number of styles and number of cells in the ovary as well as in the shape of pyrenae. In Acanthopanax the number of styles and the cells of ovary is 2, rarely 3. The number of styles and cells of ovary in Eleutherococcus is 5, sometimes 8 to 6. The pyrenae of Acanthopanax are flat or slightly roundish on their ventral side, but those of Eleutherococcus are acute or acutish. I therefore re- move all the species of Acanthopanax having 5-celled ovaries and place them under Eleutherococcus. These are E. pentaphyllum, E. Giraldit, E. Rehderianum, E. cissifolium, E. stenophyllum and E. Wilson.

Koehne made a thorough study of this species from plants cultiv 4 in Germany and published the results in Mitteilungen der Deutschen Dendrologischen Gesellschaft no. 22 (1913). He stated that there are three distinct forms: 1) those Ravi leaves shallowly cleft remaining unchanged through the age of the tree; 2) those having leaves deeply and narrowly cleft when young but shallowly cleft when old; 3) those having leaves shallowly cleft when young but deeply and narrowly cleft when old. As Siebold’s specimens kept in the herbarium of the university of Leyden have the leaves lobed in various forms he took var. Mazimowiczii Schneider as the name for his second and third group, and var. magnificum Zabel for his first group. His classification is principally based upon the plants cultivated in Germany and he paid no attention to the pubescence of leaves jeri is a marked characteristic of the species. There are many in Japan and it is hard to draw any definite distinctions. 1. Leaves pee shallowly lobed and sparsely hairy.

5. Leaves shallowly lobed and sparsely hairy on young, deeply lobed and densely hairy on mature trees.

By Siebold (Florae Japonicae Familiae naturales, n. 410 |1846]) the species was described as with “foliis alternis longe petiolatis e basi sub- cordata vel truncata orbicularibus profunde palmato-quinquefidis, lobis oblongis acuminatis argute serratis glabris coriaceis,”’ and further in the detailed notes below he makes the following statement: “lamina basi subcordata, rotundata vel truncata, orbicularia, ad medium circiter usque palmato-quinqueloba lobis oblongis acuminatis lateralibus parum brevi- oribus, utrinque glabra subtus dense reticulato-venosa. ’

us we readily see that our first and second groups correspond to Siebold’s Panaz ricinifolium, though the specimens at Leyden show a variety of forms. Our first and second groups should therefore be named var. typicum. The third is Acanthopanaz ricinifolium var. magnificum or Acanthopanax acerifolium Schelle. The fourth and the fifth are Aralia Mazimowiczii Van Houtte. The first group is found in Hondo; the second is distributed through Hondo, Korea, Quelpaert, Manchuria, Ussuri and China; the third is distributed in Yeso, Hondo, Korea and China; the fourth and fifth are in Yeso, Hondo and China. Koehne says, “Blii- hende Zweige mit tief geteilten Blittern sind noch nicht bel tg len” thus flowers of var. Marimowiczti have not been seen in Germany. But we have a flowering specimen of the variety collected in the province of Shinano and I myself have seen the same type not rarely in the mountains of the province of Kai. Therefore this should be the type of a distinct variety. In the Arnold Arboretum there is growing a tree of this variety which was introduced from France. It is now of good size but has not yet flowered. There are also in this Arboretum three large trees of this species raised from seed collected by Professor Sargent in Yeso. They cor- respond to our third type. Another tree raised from seed collected by Mr. J. G. Jack in Yeso in 1905 is also of the third type, yet it is less hairy.

The Liukiu type which is just like the figure a of Koehne and as Tafel 5, fig. A of Harms has leaves whose main ribs approximately radiate from the base of the leaves, but the leaves are always 9-lobed. In general the leaves of the flowering branches of this species are 5—7 ribbed. The Chinese plants which have very short lobes belong to var. chinense.

This species is the plant from which the Korean yellow lacquer is obtained. The Koreans ruthlessly slit every trunk which they find in the woods to cause the lacquer to secrete. The lac yuer is insoluble in water and never deteriorates if kept therein. The yellow furniture seen in Korean shops is lacquered with it. Gulibertia trifida, the Japanese species, is similar in its appearance, but the resin found within the bark is color- less. It is of smaller size than the Korean species, and its fruit is spherical.

As H. Harms has already pointed out (in Bot. Jahrb. xxi. 20-21 (1896) ) Pentapanar racemosum and P. subcordatum are better separated from the other species of Pentapanax; they are terrestrial plants with the inflorescence arranged in racemes.

Formosa: Funkiko, B. Hayata; in monte Arisan, prov. Kagi, E. H. Wil- son, no. 10899.

Dr. Hayata seems to have based his description of the flowers on the figures drawn by F. Hayami who mistook the black fungus on the half rotten specimen for hairs. He also overlooked the existence of Pentapanax verticillatum, P. yunnanense and P. Henryi in China and wrote of the genus as new to the East Asiatic flora.

The variety sachalinensis differs from the type in its pubescent calyx. Regel says “‘Bliithenstiele und Fruchtknoten dicht kurzhaarig.”” His Fruchtknoten does not mean ovary but the calyx-tube. In the type the calyx-tube is perfectly smooth. Fr. Schmidt (in Mém. Acad. Sci. St. Pétersb. ser. 7, X11. no. 11. 141 [1868] ) says “Calycibus majoribus oblongis quam petala longioribus.”’ If this character is true for his specimen, it must be a variety distinct from the true sachalinensis; in Regel’s figure the lobes of calyx are small and never exceed the petals. Makino’s var. sachalinensis is the typical Udo, Aralia cordata, as the specimens bearing this name in his handwriting prove.

According to 5S. Sasaki, this shrub grows in dry barren land of the tem- perate mountain region at about 1000-2100 m. above sea-level in Formosa. It is usually found growing in a higher zone than Aralia Decaisneana, rarely coming down to 300-600 m. or even to the plain in the Koshun peninsula.

This species is distinguished from both Aralia spinosa and A. chinensis by the form of the inflorescence. In these two species the main axis of the inflorescence is elongated terminating the branch of the current year. Thus the inflorescence forms a terminal erect panicle. In A. elata the axis of the inflorescence is short and its main branches are well devel- oped and more or less umbellate. The main branches of the inflores- cence become themselves panicled spreading when in flower and drooping in fruit. Aralia spinosa has distinctly stalked leaflets by which it is distinguished from either A. elata or A. chinensis. A. chinensis has or- dinarily finer serrations and more tapering leaflets than A. elata. We have an imperfect glabrescent specimen from Formosa. It lacks the inflorescence and I cannot ascertain to what species it really belongs. According to S. Sasaki this type grows in the whole island of Formosa below 1000 m. above sea-level and does not branch. A specimen from Western China (Wilson’s no. 3692) has the leaflets minutely but sparsely ciliated all over the lower surfaces, but the pubescence is not velutinous as in the type.

Linné’s Panax comprises Panazx trifoliatum, P. quinquefolium and P. fruticosum. The last, however, is a species of Nothopanax with double pinnate leaves and valvate petals. Many authors like Houttuyn, Jussieu, Willdenow, Aiton, Endlicher and others have followed him. But from the time of A. P. de Candolle many species of the Nothopanax-type have been added to the genus and its characters gradually have come to represent the conception of Decaisne & Planchon or Bentham & Hooker. Seemann who made a thorough study of the Araliaceae known at his time reverted to the Linnean conception of the genus and improved it by ex- cluding from it Panax fruticosum. Harms has followed him and this is really the best disposition.

C. A. Meyer remarks:

“‘Erst v. Siebold, dem wir so viel fiir die Sear Japan’s zu verdanken haben, machte auf die Verschiedenheit dieser Pflanzen, sowie des japanischen Ginschen, pea siperobes un ees von Esenbeck sah ch veranlasst, zwei Arten anzuneh-

=e Nee Panazx quinquefolius und den asiatischen P. Schin seng; diese ltztere Art umfasst, nach des Verf mee sagen den Riateanieeet chinesis- n japanishen Ginschen, so nepalischen P. Pseudo-ginseng.’ (See Bull. Phys. -Math. Acad. Sci. St. eee e 339 [1824]).

Though Meyer’s name Panazx japonicum might possibly have been derived from Siebold’s Panaz quinquefolium b. japonicum, his description is based entirely on the figure of Nees, since he says “Plantam non vidi, sed ex icone speciem omnino distinctam esse credo,’’ and Siebold did not have a figure, while Nees von Esenbeck published an excellent colored plate in his Icones Plantarum Medicinalium. According to Meyer’s description “rhizomate repente, fibris lateralibus fusiformibus; squama decidua ad basin caulis; foliolis 5 oblongis acuminatis profunde serratis”’ the plant cannot be any other than this species. Eliminating the synonym P. quinquefolium b. japonicum Siebold, the name P. japonicum becomes the correct name for this species and Panazx repens becomes its synonym. So far as I know there is no yellow-fruited Panar Ginseng. I think Siebold made his note from memory and mistook Panax japonicum and his specimen of Panax schin-seng for the same species.

In agris Japonicis et Koreanis colitur.

Although Panax Ginseng C. A. Meyer is the best name for the Korean Ginseng, P. schin-seng precedes it by ten years. Panaax schin-seng has three varieties of which two belong really to two distinct species. When a species is subdivided into varieties by an author such as a, b, ¢ or 1, 2, 3 or giving names of their own and the co-ordinate descriptions are followed it is natural to adopt the first variety for the type. Panax schin-seng is one of these cases and moreover it is furnished with colored plates which no one can mistake for any other species. This is the reason why the name Panax schin-seng is adopted here.

The author started this investigation at the Tokyo Imperial University and finished it at the Arnold Arboretum of Harvard University. He wishes to express his great appreciation of Professor Sargent ’s courtesy in allowing him to avail himself freely of the library and the herbarium of that institu- tion. The author wishes also to thank Mr. E. H. Wilson for useful help and to Miss Tucker for her courteous assistance in the library. And he wishes especially to emphasize his sense of gratitude toward Mr. Rehder for his valuable criticisms and suggestions.

“The Chinese specimens [of Ehretia acuminata] agree well with Ben- tham’s full description of Brown’s species, and in the absence of Australian material of the typical plant there is nothing to be done but to follow Clarke and others in referring the Asiatic plant to Brown’s species. Never- theless, I am sceptical as to the two being conspecific, since such distri- bution is contrary to all we know of Chinese woody plants.”

This is a note by Mr. E. H. Wilson when he enumerated the Chinese Ehretia in Sargent’s Plantae Wilsonianae. Agreeing in this opinion I have lately studied all the material of Ehretia acuminata and of the allied species in the Arnold Arboretum Herbarium. Fortunately I have been able to see both flowering and fruiting specimens of Ehretia acuminata from Australia and of the related species. They are indeed closely related but have some remarkable distinctive characters. The most important character distinguishing FE. acuminata from allied species is the shape of the anthers. In E. acuminata they are roundish and the connective is not produced while in the other species they are oblong and the connective exceeds the anther-tips. Next to the shape of the anthers, the pubescence and the persistence of the leaves, the color and nature of the fruits are prominent characters of the group. According to these characters the species may be distinguished as follows:—

This is nearest to Ehretia serrata, but the color of the twigs is different. I saw specimens’ taken from a tree cultivated in the Botanic Garden, at Buitenzorg, Java. It seems different from either E. serrata or E. acuminata, but the material is not sufficient to decide this. According to F. Mueller (I. c.) the leaves of E. acuminata are deciduous, but I think this is a mistake. The flowering specimens in the Arnold Arboretum Herbarium were col- lected in the garden of Palace Grounds of Sydney in April and the fruiting specimen on the Blackall Range in January. They show that the flowers appear in autumn and fruit ripens in summer, the leaves remaining through the winter. Ehretia thyrsiflora Nakai, Trees Shrubs Jap. 1. 327, fig. 179 (1922); Fl.

Ehretia Dicksoni has been often mistaken for E. macrophylla from which it differs in its racemosely arranged flowers on the branchlets of the in- florescence. Mr. E. H. Wilson tells me he is now of the opinion that Ehretia Dicksoni is distinct from the Himalayan E. macrophylla. He saw many plants of KE. Dicksoni in Paris where it is quite hardy and flowers and fruits freely and is considered a good tree to plant in streets where small trees are desired. Ehretia Dicksoni is a variable plant and its varieties

Aesculus glabra var. monticola, n. var.

Differing from the type in its dwarf habit, small fruit and often 7 leaflets.

Leaves 5~7, usually 5-foliate, their petioles glabrous, 7-15 cm. in length; leaflets oblong-obovate to elliptic, abruptly or gradually narrowed and long-pointed at apex, cuneate at base, coarsely often doubly serrate with acuminate teeth, glabrous with the exception of a few short hairs early in the season on the upper side of the midrib and principal veins, 10-12 em. long and 4.5-5 cm. wide, their petiolules glabrous or sparingly pilose, 1-10 mm. in length. Flowers rather smaller but otherwise as in the type. Fruit subglobose, 1.5-2 cm. in diameter, usually 1-seeded; seeds subglobose or depressed and often nearly twice as broad as high, dark chestnut brown and marked by an oval or nearly circular hilum 6-7 mm. long.

A shrub 1-2 m. tall.

leaflets and much larger flowers. In the number of leaflets and in their shape and serratum it is nearer to the var. Buckleyi Sarg. than to the type.

X Aesculus arnoldiana (A. glabra X A. hybrida), n. hyb.

Leaves 5-foliolate, their petioles deeply grooved onthe upper side, puberu- lous toward the apex, 8-15 cm. in length; leaflets elliptic, long-pointed and acuminate at apex, cuneate at base, finely, often doubly serrate, sparingly floccose-pubescent early in the season becoming glabrous or nearly glabrous above, pubescent along the under side of the midrib and of the from fifteen to twenty pairs of primary veins furnished in their axils with con- spicuous tufts of pale hairs, dull dark green on the upper surface, pale yel- low-green on the lower surface, 9-14 cm. long and 4-5 cm. wide; petiolules pubescent or puberulous, 5-10 mm. in length. Flowers mostly unisexual by abortion of the ovary, yellow, opening the end of May, on slender pubescent pedicels, in short broad densely flowered clusters, pubescent like the short peduncle; calyx campanulate, slightly pubescent; petals villose and glandular on the margin, those of the upper pair marked with red; stamens nearly as long or slightly longer than the petals, sparingly, villose. Fruit roughened by the scattered prickles and occasional by their bases, subglobose, 2-3 cm. in diameter, 1-3-seeded; seeds light chestnut- brown, up to 2 em. in diameter, hilum 5-6 mm. in diameter.

This tree which sprung up several years ago in the Aesculus Group of the Arboretum in the immediate neighborhood of flowering plants of its supposed parents is a tree from 6.5 to 7 m. high with a slender trunk covered with pale scaly bark. In general appearance it might be taken for a plant of A. glabra from which it differs in the shorter stamens, smaller only slightly roughened fruit and in the presence of glands mixed with the hairs on the margin of the petals showing the influence of one of the Eupa- viae. None of the species of this group had flowered in the Arboretum when the seed which produced this tree germinated and the glands on the margin of the petals can only be accounted for by the influence of A. hybrida D. C., a hybrid it is believed between A. Hippocastanum and A. Pavia, one of the red-flowered Eupaviae.

Aesculus octandra var. vestita, n. var.

Differing from the type in the coating of pale tomentum or pubescence on the lower surface of the leaflets and on the petioles and branchlets. This form of the yellow flowered Buckeye which is widely distributed with the species appears to be more abundant westward than on the southern Appalachain Mountains where Aesculus octandra grows to its largest size and is most abundant.

In the herbarium of this Arboretum are the following specimens of this variety:

Among cultivated plants the Aesculus neglecta Baenitz (Herb. Dendr. without number “Breslau: Goepperthain, 1903’’), not Lindley, and Hort. Goettingen, A. Rehder, no. 1571, belong to this variety.

It has been cultivated in the Arboretum since 1898 when a plant was received from the Meehan Nursery at Germantown, Penn. (no. 8121); in 1900 a plant was received from the Spaeth Nursery at Berlin, Germany (no. 8123); and in 1907 the seeds collected on Craggy Mountain, North Carolina, by T. G. Harbison, produced a number of plants (no. 13276).

The covering of the lower surface of the leaflets of the tree from Pike- ville, Kentucky, (Horsey no. 947), is distinctly tomentose, and similar tomentum occurs on several of the other specimens in this herbarium. On other specimens the lower surface of the leaflets is pubescent, sometimes only slightly so, showing the transition to the normal form of Aesculus octandra in which the lower surface of the leaflets is glabrous or occasionally slightly pubescent early in the season with deciduous hairs except along the under side of the midrib and principal veins. The amount of the pubes- cence on the petioles and branchlets also varies in different individuals.

Lindley’s description of this species was made from a tree growing in the garden of the London Horticultural Society at Chiswick, which had been purchased from a Monsieur Catros of Bordeaux under the name Aesculus ohioensis. Spach took up Lindley’s name and spoke of the tree as common in cultivation in 1834. Koehne in 1893 (Deutsche Dendr. 386) suggested that it was a hybrid of A. discolor and A. octandra, but the margins of the petals in Lindley’s excellent plate show no trace of the glands among the hairs which indicate hybrid origin in Aesculus. The petals are pale yellow marked by small red blotches.

44 JOURNAL OF THE ARNOLD ARBORETUM [VoL. v

I have never seen a wild Buckeye with flowers which resemble those figured by Lindley, but Colonel Henry A. du Pont of Winterthur, Delaware, has recently called my attention to two trees planted by his grandfather the leaves and flowers of which cannot be distinguished from those repre- sented by Lindley’s plate.

Eleuthére Irénée du Pont de Nemours, the founder of the Dupont Family in America, came from France in 1800 to America where he lived first at Hackensack, New Jersey, but in July 1802 moved to Delaware where he established his powder works and built a substantial stone man- sion on the banks of the Brandywine in Christiana Hundred, about four miles from Wilmington at the place which has now for one hundred and twenty-one years been known as Eleutherean Mills.

A family tradition, preserved by the now oldest Du Pont who asa boy gathered nuts from the trees, records the fact that Mr. Antoine Bidermann who had married Du Pont’s second daughter Evelina and had become associated with him in the powder business had gone to New Orleans some time after 1820 to inspect there the agency of the powder mills and had returned home on horseback through Mississippi, Alabama and Georgia, and that during this journey he had picked up the nuts from which the Eleutherean Mills trees had grown.

The soil on the steep slope in the rear of the Du Pont mansion is deep and rich, as is shown by the size and vigor of the native Oak-trees which are growing in it, and the two large Buckeyes on this slope, the trees which in the color of their flowers so closely resemble the flowers of Lindley’s plate, are 32 and 28 metres high with a trunk girth at 3 feet from the ground of 2.35 and of 2.10 metres. The larger of these two trees is the tallest and largest Buckeye of any variety of which authentic measurements have been made.

The conclusion which an examination of these Eleutherean Mills Buckeyes has forced on me is that there are no real characters by which the plant I have named Aesculus georgiana can be distinguished from the Aesculus neglecta of Lindley which, if this view is accepted, becomes the type of the species of the Octandrae which in various forms is widely distributed in the Piedmont region of North and South Carolina and north- ern Georgia, occasionally ascending the Blue Ridge in North Carolina to altitudes of 3000 feet, and is common in central Georgia, ranging east into Richmond County and south into northern and central Alabama, and to an isolated station near Pensacola in Florida.

It varies from a tree 17 or 20 metres tall to a shrub which flowers and produces abundant fruit when not more than 1 metre high. The leaflets of the type and of one variety are glabrous on the lower surface, but in one form they are pubescent, and on another densely tomentose. The flowers of A. neglecta are borne in elongated slender clusters, but in the plants now considered its varieties the flower-clusters are often short and crowded and the petals are yellow, more or less marked with red or entirely red.

1924] SARGENT, NOTES ON NORTH AMERICAN TREES, XII 45

I have not seen specimens of wild trees which exactly resemble the type of A. neglecta as represented in Lindley’s plate and by the two large trees at Eleutherean Mills, but three specimens presented to the Arboretum herba- rium by Mr. W. W. Ashe resemble the type in their narrow elongated flower clusters and in the size and shape of the yellow flowers which, however, are without the red markings of those of the type; these specimens can perhaps be referred to A. neglecta rather than to any of its varieties. Mr. Ashe’s specimens are labeled “Aesculus sp. nov. Alamance County, N. 2 near Saxapahaw, about June 1, 1900, W. W. Ashe;” “A. sp. nov. near Williamsville, Dunham County, N. C., May 13, 1904, and Aesculus sp. noy., Chapel Hill, N. C., April 20, 1915, sent me by Dr. Coker at my request from tree on the Hillsboro road, W. W. Ashe.”

The more distinct forms of Aesculus neglecta may be arranged as follows:

Aesculus neglecta Lindley. Leaflets glabrous on the lower surface; flowers in elongated rather open clusters; petals pale yellow or nearly white, marked by small red blotches.

Aesculus neglecta var. georgiana, n. var. d Shrubs, 1. 359, t. 197 (1913); Man. 22),

Aesculus georgiana Sargent in Trees an rees N. Am. ed. 2, 706, f. 635 (19

Differing from the type in the shorter, broader and more densely flowered corymbs; in the typical form calyx red on the upper side and pale yellow on the lower side; petals bright yellow, passing into forms with entirely red or yellow flowers.

Usually a low broad shrub, occasionally a tree from 14 to 20 metres in height.

The type station for this variety is in De Kalb County, Georgia, near the base of Stone Mountain; it ranges northward in Georgia to the northern border of the state and is very abundant in Banks, Rabun and Habersham Counties; it occurs in Seneca and Oconee Counties, South Carolina, T. G. Harbison, no. 1, May 15, 1915, and nos. 7 and 9, April 9, 1918, and ranges northward in the Piedmont region to Durham County, North Carolina, T. G. Harbison, no. 6, April 22, 1918. It is the form which has been found in Alabama by C. Mohr, Madison Co., Mt. Sano, September 26, 1881, “large tree 80-85 feet high;”’ Tuscaloosa County, Tuscaloosa, rocky banks of the Warrior River, and in Eltowah County, Attalla, by jee Harbison, nos. 198, 209, October 8, 1910, “low shrub.” It is this form with yellow flowers which occurs in western Florida near Pensacola growing as a small shrub, T. G. Harbison, April 11, 1915, March 21, 1916.

Differing from the type and from the var. georgiana in the pubescence covering the lower surface of the leaflets.

The type of this variety was raised at the Arboretum in 1905 from seeds collected by T. G. Harbison in De Kalb County, Georgia, near the base of Stone Mountain.

or slightly villose at the base, petals yellow or yellow slightly tinged with red, their margins glandular and villose.

A tree 29.15 metres in height, with a trunk 2.25 metres in girth at one metre above the ground, covered with scaly bark, stout yellow branch- lets and pale brown winter buds 2 cm. long.

This tree was planted by the fence near the right hand side (facing the house) of the entrance to Eleutherean Mills after 1820 by Eleuthére Irénée du Pont de Nemours and probably sprang from one of the seeds collected by Antoine Bidermann during his journey on horseback from New Orleans. This Buckeye, which is one of the most interesting of the trees which have been planted in the United States, may well preserve among tree lovers the name of a family which in at least four generations has made the neighborhood of Wilmington, Delaware, one of the chief centres of horticulture in the United States.

Xx Aesculus DuPontii var. Hessei (A. neglecta georgiana X Pavia), n.

r.

Leaves 5-foliolate, their petioles stout, puberulous early in the season, 7-15 cm. in length; leaflets elliptic to slightly obovate, gradually narrowed and long-pointed at apex, cuneate at base, usually doubly serrate with slender slightly incurved teeth, glabrous, dark green above, lighter and yellow-green below, 10-13 cm. long and 4-5 cm. wide, with a prominent yellow midrib and from 20-25 pairs of slender primary veins often furnished with small tufts of axillary hairs; petiolules puberulous, 3-9 mm. long. Flowers appearing late in May, up to 3 cm. in length, red or yellow tinged with red, on short villose pedicels in compact densely crowded villose clusters 12 or 13 em. long; calyx narrow-campanulate, slightly villose toward the apex, usually red, the petals yellow more or less tinged with red, villose and glandular on the margin.

This shrub was presented to this Arboretum in 1909 by the Hesse Nur- sery at Weener, Germany, with two other hybrid Buckeyes, under the name of Aesculus (Pavia) nana rosea “de semis.”” The presence of both hairs and glands on the margin of the petals indicates its hybrid origin. The leaves cannot be distinguished from those of Aesculus Pavia, while the inflorescence and the flowers only differ from those of A. neglecta georgiana in the rather narrower calyx and in the glands on the margin of the petals.

This tree was well described by Spach, although the pubescence along the sides of the under surface of the midrib and in a lesser degree of the veins of the leaflets of the Arboretum plants presented by the Spaeth Nursery at Berlin, Germany, are not tomentosae on the veins as Spach de-

scribed it but villose. He failed, however, to notice the glands scattered among the hairs on the margin of the petals which indicate that it is a hybrid between a species of the Eupaviae and one of the Octandrae.

Xx Aesculus mutabilis var. penduliflora (A. discolor mollis < neglecta),

. hyb.

Leaves 5-foliolate, their petioles glabrous, 10-16 cm. long; leaflets oblong-lanceolate, acuminate and long-pointed at apex, gradually narrowed and cuneate at base, finely serrate with gland-tipped teeth, dark green and glabrous except on the midrib and veins above, pale and soft pubescent below, 12-16 cm. long, 4-5 cm. wide, with 22 or 24 pairs of primary veins; petiolules pubescent, 7-10 mm. in length. Flowers opening early in June, on slender glandular pedicels 5-10 mm. long, in narrow slightly pendent sparsely flowered densely pubescent clusters 14-16 cm. in length; calyx tubular, reddish covered with red glands, 5-6 mm. in diameter; corolla yellow, glandular, the margin of the petals covered with hairs mixed with glands. Fruit nearly globose, smooth with a thin pericarp; seed sub- globose, dark chestnut brown and lustrous, 2-2.5 em. in diameter, the hilum oblong or oval, 8-10 mm. in length.

As it grows in this Arboretum this is a narrow slender tree now about 8 metres in height, with a trunk 25 cm. in diameter covered with thin dark brown scaly bark; it was presented to the Arboretum in 1902 by the Spaeth Nursery near Berlin, Germany, under the name of Aesculus humilis X lutea.

The shape of the leaflets and the elongated flower clusters point to the typical form of A. neglecta, while the pubescence on the lower surface of the leaflets and the color of the flowers suggest that A. discolor mollis may have been the other parent. The long narrow leaflets and the elongated and pendent clusters of brilliant flowers make this one of the most distinct and beautiful of the hybrid Buckeyes.

x Aesculus mutabilis var. induta (A. discolor mollis X neglecta), n. b

yb.

Differing from the type in the pale tomentum covering through the season the lower surface of the leaflets.

This variety is based on two of the three plants presented in 1909 to the Arboretum by the Hesse Nursery in Weener, Germany, as Aesculus (Pavia) rosea nana “de semis.”” It is probably the Aesculus neglecta Baenitz (Herb. Dendr. without number “Breslau: Siidpark, 1905’’), not Lindley. It was cultivated in 1904 in this Arboretum under the name of A. octandra hybrida (No. 1636-2) now dead.

CORRECTION

In the second edition of the Manual of the Trees of North America, 806 (December 1921), the Marlberry, a small tree of extreme southern Florida, was transferred from the genus Icacorea to Ardisia and called A. paniculata Nuttall. Nuttall, however, never made such a combination,

which must be credited to Sargent. The name, moreover, is not a valid one, having been used for another plant in 1814 by Roxburgh. The correct name for the Florida tree appears to be Ardisia escallonioides Chamisso & Schlechtendal in Linnaea, vr. 393 (1831). (See C. Mez, Myrsi- naceae in Engler, Pflanzenr. 1v.-236, 81 [1902]).

In 1819 Rafinesque proposed the name Xolisma for Lyonia of Nuttall for the reason that the name Lyonia had been given by him in 1808 (in Med. Rep. N. Y. v. 353) to another genus, but that name was only a new name to replace Polygonella Michaux, which Rafinesque considered in- appropriate; therefore it is not a valid name and will remain a synonym of Polygonella. There is, however, another Lyonia proposed in 1817 by Elliott (Sketch Bot. S. C. I. 316 [1817] ) which antedates Lyonia of Nuttall and is a valid name for a new genus based on Ceropegia palustris Pursh (Cynanchum angustifolium Muhlb.); later the same genus was named Seutera by Reichenbach (Consp. 131 [1828] ) and this name is taken up by Small, as according to the Philadelphia Code Lyonia Elliott is invali- dated by the older homonym Lyonia Rafinesque of 1808, but according to the International Rules the latter name is not valid and therefore Lyonia Elliott remains the oldest and valid name for the genus of Asclepiadaceae, which makes it necessary to take up for Lyonia Nuttall the next oldest name which is Xolisma. The type species of this genus is Lyonia fer- ruginea Nuttall in which the character of the thickened sutures of the valves is most pronounced and the thickened part separates from the rest of the capsule, while in other species as in X. ligustrina, X. mariana, X. lucida and X. ovalifolia the thickened part, though clearly perceptible by its light color is apt to separate more irregularly from the rest of the valves and does not hold together so firmly like a separate valve as it does in X.

ferruginea and its nearest relations. Xolisma mariana, X. lucida and X. ovalifolia have been referred by Bentham and Hooker and other authors to the genus Pieris, but they differ from that genus not only in the thickened sutures of the capsule, but also in the awnless anthers; apparently these authors did not consider the structure of the capsule and did not distinguish between appendaged or awned anthers and the appendaged filaments of these species; they considered the appendages of the filaments as equal in taxonomic importance to the awns of the anthers, but the former consti- tute a less constant character and the appendages may become more or less indistinct or obsolete and are entirely absent in some species of Xolisma as in X. villosa, while the awned anthers constitute a constant and important character.

This variety is nearest to X. ligustrina foliosiflora C. Mohr, which in its typical form has nearly glabrous leaves lustrous above and usually a more leafy inflorescence with a nearly glabrous corolla (Andromeda paniculata var. 2, foliosiflora A. floribus:glabellis Michaux, F]. Am.-Bor. 1. 255 [1803] ), while the variety has the leaves grayish above from a dense covering of short appressed hairs, becoming glabrescent at maturity, loosely or sparingly villose on the surface beneath and densely villose on the midrib and on the prominent veins; the inflorescence is usually less leafy and the corolla densely hairy with short stiff hairs except at the base. The speci- men in this herbarium which shows these characters most markedly is from a cultivated plant collected by H. Zabel in the Botanic Garden at Muenden, Germany; this plant had been received in 1871 from the Booth Nursery at Flottbeck, Germany, under the name Andromeda tomentosa and is no doubt the plant described by Dumont de Courset under that name; by Kirchner (in Petzold & Kirchner, Arb. Musc. 468 [1864] ) it was erroneously referred to Xerobotrys tomentosa Nuttall (= Arctostaphylos tomentosa Lindl. )

This species which is native to the coastal plain from Virginia to Florida and Louisiana and is also found in Cuba has been made by Small the type of the new genus Desmothamnus chiefly distinguished from typical Xolisma by the appendaged filaments and the pair of intra-m arginal veins of its leaves, but the absence or presence of teeth or appendages near the apex of the filament does not seem to be a strong morphological character, and in some species these appendages though present become obsolete; it therefore does not seem wise to use this character for generic distinction.

This form is easily distinguished from the type by the soft pubescence of all its parts except the corolla; the leaves of the type specimen are gen- erally elliptic-oblong and from 4 to 6.5 cm. long and 1.3 to 3 em. wide. The branchlets, calyx and leaves of the typical form are glabrous or some- times the midrib and veins on the under side of the leaves are slightly or rarely rather densely villous and the calyx is sometimes sparingly hairy, but none of the numerous specimens seen from the whole range of the species approach this new form in its densely villose pubescence. I have seen no other material of X. mariana from Texas and I find no record of its range extending as far west; the most western specimens seen are from Jefferson and Pulaski Counties in southeastern and central Arkansas (E. J. Palmer, nos. 8481 and 22999).

This variety differs chiefly in the narrower leaves, usually broadly cuneate at base or sometimes rounded and in the longer and narrower greenish sepals. It seems to have about the same range as the type.

This nee differs chiefly in its thinner leaves and smaller fruits (3-4 mm. in diameter) from the type which has coriaceous leaves and larger fruits 4-5 mm. in diameter; none of the other characters given by Siebold & Zuccarini to distinguish the Japanese plant from that of the Hima- layas holds. This variety is widely distributed through China except in the northern provinces and is also common in central and southern Japan.

This cee is ae aie in general appearance and in most of its characters to the preceding species but is easily distinguished by the pubescence on the under side of the leaves, by the shorter inflorescence, by the lanceolate longer calyx-lobes divided nearly to the base and by the absence of the appendages of the filaments. It occurs at altitudes of from 3000-4000 m. on the Himalayas from Ghurwal to Sikkim and also in western China as far north as western Szechuan. Judging from the des- cription I have little doubt that Léveillé’s Pieris Henryi belongs here.

This variety differs from the type in its pubescent ovary and is known only from western Szechuan.

Of this species I have not seen the type but a specimen collected in the Yunnan Fu district by O. Schoch (No. 145) and determined as P. compta by Schneider agrees well with the original description except that the calyx-lobes are ovate and obtuse rather than ovate-lanceolate and acutish and the ovary is ovoid and not depressed globose; the longest leaves of Schoch’s specimen are up to 3.5 cm. long and the minute dots of the under side are not black. The general appearance of the plant suggests a species belonging in the affinity of X. ovalifolia and an examination of the stamens confirms this opinion; the anthers are without awns or appendages, not

biaristate as described by the authors, but the filaments have near the apex back of the anther-cells a pair of appendages in shape and size like those of P. ovalifolia. Of Pieris bracteata W. W. Smith I have seen no specimens but from the statement “filamentis . . . apice biaristatis” I infer that it also belongs to Xolisma. Piers Forrestit Craib is a true Pieris and so is P. polita W. W. Smith & J. F. Jeffrey to which I refer one of Dunn’s specimens collected in Fokien (Hongkong Herb. No. 2894). Of the numerous species of Pieris proposed by Léveillé I have seen no material and his descriptions are too incomplete to be guided by them. But I may say that P. Bodiniert appears to be a true Pieris judging from his drawing (in his Cat. Pl. Seutchouen, t. 24 [1918] ) and that his P. Henryi probably belongs to Xolisma villosa; some of his species may not belong to the Andromedeae at all, but to Vaccinium as his P. coreana and P. Fauriei which according to Dr. Nakai who has seen the type specimens are both Vaccinium bracteatum, or they belong to other Ericaceous genera.

The species of Xolisma may be divided into several well marked groups as follows:

This section, the type of which is Lyonia ferruginea Nuttall = X. fer- ruginea A. Heller, is characterized by the flowers being borne in dense axillary panicles, by the unappendaged filaments and the lepidote indu- mentum; the leaves are persistent and often toothed or undulate; the capsule is usually ovoid, prominently angled and the thickened part of the sutures separates as a whole from the rest of the capsule. Its many species (24 being enumerated by Small in N. Am. Fl. xxix. 65-72), are mostly natives of the West Indies; two occurring in the southeastern United States and a few in Mexico.

with less thickened sutures; the leaves are deciduous and glabrous or pubescent. This section contains only one variable species native to the eastern States of North America distributed from Maine to Florida and Louisiana. The sectional names Lyonia and Eulyonia cannot be used, as these sections do not contain the type of Lyonia which is L. ferruginea G. Don and belongs to the preceding section. Sect. III.

This section, the type of which is Andromeda mariana L. = X. mariana Rehd., is chiefly characterized by the flowers borne in axillary clusters on the branches of the previous season, by the appendaged filaments, the ovoid or globose-ovoid capsule with prominently thickened sutures; the leaves are entire, persistent or deciduous and glabrous, rarely puberulous or pubescent. The two species are native of eastern North America and are distributed from Rhode Island to Florida and Louisiana; one of the species is also found in Cuba.

This section, the type of which is Pieris ovalifolia (Wall.) Don = X. ovalifolia Rehd., is characterized by the flowers borne in axillary and terminal on-sieded usually elongated racemes, by the less strongly thick- ened sutures and the usually appendaged filaments (without append- ages in X. villosa Rehd.); the leaves are entire, persistent or deciduous and glabrous or more or less pubescent. The species of this section are all Asiatic and distributed from Kashmir through the Himalayas to western and eastern China, to central and southern Japan and to Formosa. The sectional names Pieris and Eupieris cannot be used, as they do not contain the type species of Pieris which is P. formosa Don and belongs to a distinct genus.

This variety differs in its oblong or narrow-oblong less revolute leaves from the type which has linear or linear-oblong leaves. Link’s description of his A. glaucophylla is apparently based on a plant cultivated in the Botanic Garden at Berlin and as he describes his species as with “‘foliis linearibus,” the narrow-leaved form must be considered the type. The citation of Pursh’s A. polifolia 8. as a synonym does not necessarily indicate as Fernald assumes (in Rhodora, xvim. 100 [1916] ) that Link based his species on Pursh’s variety, for in this case Link is describing a plant cul- tivated in the Berlin Botanic Garden and that plant of which possibly specimens are preserved in the Berlin herbarium is to be considered the type. Considering the specific name I fully agree with Professor Fernald that A. glaucophylla Link is the same plant as A. canescens Small which has to be referred as a synonym to it, and that it is notidentical with A. polifolia as Small (in N. Am. Fl. xxrx. 61 [1914] ) has it.

As there can be hardly any doubt that Erica Watsoni and E. Mackai are both hybrids between E. ciliaris L. and E. Tetraliz, they should be united under the oldest binomial designation which is E. Mackati Hook., and FE. Watsoni which differs from typical EF. Mackazi chiefly in its racemose inflorescence and the longer corolla with oblique mouth may be distin- guished as a variety.

The Chinese specimens enumerated above all differ in their smaller much narrower leaves never cordate or subcordate at the base, as they often are in the Japanese type in which, moreover, the petioles and the leaves are always quite glabrous. In its pilose filaments and its narrow leaves the variety resembles V. japonicum var. lasiostemon Hayata (Icon.

1924 REHDER, NEW SPECIES, VARIETIES AND COMBINATIONS 57

Pl. Formos. 1. 115, t. 12 [1912] ) from Formosa, but the leaves of the For- mosan variety are quite glabrous according to the description. Dr. Nakai has proposed for V. japonicum Miq. and V. erythrocarpum Michx. the new genus Oxycoccoides (in Tokyo Bot. Mag. xxx1. 246 [1917] ), but in doing so he overlooked the fact that Small in 1903 (in his Fi. S. E. U. S. 896, 1336) based the new genus Hugeria on V. erythrocarpum and as the two species are undoubtedly congeneric differing only in minor characters, the oldest name for this genus, if separated from Vaccinium or from Oxycoccus, will be Hugeria Small. e name Oxycoccoides pro- posed by Bentham & Hooker (Gen. PI. 11. 574 [1876] ) as a section of Vac- cinium though older than Hugeria, cannot invalidate a properly published generic name.

This form differs only in the glabrous or nearly glabrous under side of the leaves from typical V. molle Michx. which has the leaves densely soft pubescent beneath.

An intermediate form represents a specimen of the co-type of V. Deme- trionis Deane & Robins., a synonym of V. molle, from the Cole Camp Creek, Benton County, in the Herbarium of the Arnold Arboretum, the leaves of which are very sparingly pubescent with mostly forked hairs beneath, except the veins which are more densely pilose with mostly simple hairs; other specimens from the same locality have the leaves densely pubescent beneath as in the typical form, while Trelease’s No. 4 cited above has nearly glabrous leaves. Of the type there are specimens from the following localities in the Arnold Arboretum Herbarium: Danville, Kentucky (type locality), Benton County (type locality of V. Demetrionis Deane & Robins.), Christian, Stone and Boone Counties, Missouri, and Carroll and Ripley Counties, Indiana. This shows that from two localities, Cole Camp Creek, Benton County and Galena, Stone County, Missouri, both forms are represented and that the glabrescent form seems to occur only in the western part of the range of the species.

The variety bears some resemblance to V. affine Bush, but that species may be distinguished by the light brown or grayish brown, not light gray or light grayish yellow, color of the branchlets, the close bark of older

The presence of stipules on many of the petioles of the variety suggests affinity to V. affine Bush and V. molle Michx., but both these species have a very different fruit with a much flattened stone showing two lateral grooves on the ventral side, while this variety agrees exactly in its fruit with the type of V. pubescens Pursh (V. venosum Britt.) which has a globose conical or short ellipsoidal scarcely or slightly compressed stone with a deep groove in the middle of the ventral side. In typical V. pubescens and in its varieties, var. Canbyt Blake and var. longifolium Blake, the petioles are almost always without stipules, but may be occasionally stipulate on any of these three varieties, therefore it does not seem advisable to con- sider the greater or lesser prevalence of stipules a character of sufficient value to separate this and the following variety specifically from V. pu- bescens. In the size and shape of its leaves, at least in its typical form, var. Deamii has some resemblance to V. molle, but in that species the leaves are distinctly cordate at base, the branchlets are light gray or light grayish yellow and the bark on older branches separates in thin flakes. It also resembles V. pubescens var. Canbyi Blake which, however, has somewhat smaller and narrower leaves with fewer veins and glabrescent beneath and pubescent branchlets, though occasionally the under side of the leaves may be more pubescent as in a specimen from Waynesville, N. C. (Bilt-

more Herb. without no. and collector, July 27, 1903). In the pubescent underside of its leaves var. Deamii resembles var. longifolium Blake but that variety has much smaller and narrower, ovate ot ovate-oblong leaves with more numerous veins and longer teeth. From the southern V. scabrellum Chapm. which agrees with V. pubescens in the fruit and stone, var. Deamii is easily distinguished by the glabrous smooth branchlets. The leaves of some specimens resemble those of the following variety in shape and serration but they all have the under surface soft pubescent.

This variety differs from var. Canbyi chiefly in the presence of stipules on most of the petioles, by which character it agrees with the preceding variety; it also differs in the generally coarser serration of the leaves and the glabrous young branchlets, though occasional specimens of the latter variety show the same kind of serration and may have glabrous or glabrate branchlets. Some specimens as nos. 39002, 39971 and 40022 with smaller glabrescent leaves approach V. dentatum L. but may be distinguished by the presence of stipules, larger inflorescence and larger short-ellipsoidal fruit from that species which apparently never has stipules and has smaller subglobose fruit and denser smaller inflorescence.

This is a tree with ascending or upright branches though it becomes low and shrubby on wind-swept rocks. Unlike Raphiolepis umbellata it is not hardy in Tokyo and is easily distinguished from it by the mode of branching and by its leaves. The wood is hard and durable. The dis- covery of this species in Botel Tobago is interesting.

The branches of this species are more robust and more spreading

than those of Raphiolepis integerrima, and the leaves are thicker and broader. This is hardy in Tokyo and is an important plant in Japanese landscape gardening.

The collector states that this species grows in the open places and is very common in the locality cited. This seems to be an entirely glabrous plant, for the specimens collected in August bear still unfolding young leaves at the end of branches which are quite glabrous.

Raphiolepis indica is not a native of India but is widely distributed in China and Cochinchina where there are many varieties and forms, Owing to its polygamy the stamens are longer or shorter than the calyx- lobes or equal to them in length. The petals are roundish or acute at the apex. The serration and broadness of the leaves are individually different.

eee referred Linné’s Crataegus indica here, but there is no testi- mony that this plant had lanceolate petals. Linnaeus says “Corymbis squamosis’’ but nothing about the shape of petals. Loureiro says “Petala 5, subrotunda.’’ Roemer’s conception may have been induced from the remarks of Ker under Raphiolepis salicifolia in Botanical Register, tab. 652. Lindley thought that Linnaeus’s Crataegus indica was the same as Loureiro’s plant which has roundish petals. This may or may not be so but the shape of the petals is not a specific character, and both Ker’s and Lindley’s plant belong to Raphiolepis indica or Crataegus indica.

Sprengel considered this to be the Crataegus indica of Loureiro and wrote that this species had lanceolate leaves and Roemer followed him, but Loureiro’s description—‘‘ Folia cuneiformi-ovalia—apice ovata basi attenuata’’—shows that this (his) type is different and belongs to Raphio- lepis indica.

This is known only in Japanese gardens, especially in temple grounds near Kyoto. I suspect that it was brought from China as Gingko biloba, Magnolia denudata, Magnolia liliiflora, Forsythia suspensa and other plants have been, but the history is unknown. It is strange that this form only was introduced into Japan when there are so many varieties of both Raphiolepis indica and R. rubra in China.

Berthold Seemann adopted Opa as the generic name of Raphiolepis for reason of its priority. Opa includes two species: Opa odorata Loureiro which is Eugenia Millettiana Hemsley and Opa Metrosideros Loureiro which is Raphiolepis indica. The type specimens are said to be in the British Museum. From the generic description of Opa “calyx lacinis rotundatis, petala subrotunda, filamenta corolla duplo longiora,” we can readily understand that it was based on both plants. Now Opa odorata is the first species, so we must take it for the type of the genus. The generic name (pa is thus a synonym of Eugenia (or Szygium in a restricted sense) partly and that of Raphiolepis partly.

Eriobotrya ambigua Merrill (in Philipp. Bur. Governm. Labor. Bull. Xxxv. 19[1904]) has a bony endocarp and an ovary of 5 (3-4) cells, each cell containing 2 suprabasifix ovules. It should be removed to the genus Stranvaesia as Stranvaesia ambigua Nakai, comb. nov.

Eriobotrya Griffithii Franchet, Pl. Delav. 1. 224 (1899), E. lasiogyne Franchet 1. c. 225 and E. prionophylla Franchet 1. ¢. belong to Photinia.

Eriobotrya has affinities with Photinia on one side and with Raphio- lepis on the other. It has a persistent calyx though Decaisne described it as ‘Calyx 5-dentatus, marcescens vel deciduus.’’ All known species of Eriobotrya have a persistent calyx. This persistency of the calyx is an important character in this genus and in Photinia and Pourthiaea, though it is not important in other genera of Pomaceae such as Pyrus, Malus and Sorbus.

Chosenia is a very remarkable genus of Salicaceae only recently dis- covered and without seeing the flowers no one would consider it distinct from Salix. The staminate catkins are drooping, the bracts are imbri- cated and membranaceous and the five stamens adhere halfway to the bracts. The female catkins also are drooping, the bracts are membrana- ceous and caducous and the two distinct styles are subterminal and ar- ticulated at the middle. I would like to make a new subfamily, Cho- senieae, for this genus distinguished from Saliceae which would include Salix and Populus by the two distinct and articulated styles and by the ovary having neither a gland nor a cupula at the base. There is an analytical figure of a fruiting catkin drawn by C. Schneider in the her- barium of Arnold Arboretum, in which the scar of the bract is errone- ously designated as the gland; this explains the fact that in his descrip- tion of this species he attributes a gland to the pistillate flower.

Chosenia grows quickly and its trunk is straight becoming often more than 1 meter in diameter. The wood is the hardest of all known Salica- ceous trees in Korea and is used especially for bridge building. The Japanese make wooden clogs from it. The fibres are used for making rope and sandals by the Koreans.

This Oak is allied to Quercus serrata Thunb. (Q. acutissima Carruth.) but the leaves are glabrous from the beginning, the cupules and acorns are smaller and the involucral bracts are slenderer and shorter. The wood is used for the teeth of hulling mortars, for the spokes and the outer rim of wheels.

This seems to be the most common form of Quercus glandulifera in China. The typical Q. glandulifera growing in Japan, Quelpaert and Korea has long petioles (5-25 mm. long); leaves densely stellate-hairy beneath and the veins and veinlets are covered with silky hairs so that the leaves are silky when young. This typical form has not yet been found in China, but the following glabrescent variety occurs in many localities.

This plant is very common in Bonin Islands where a form of Osteomeles subrotunda K. Koch also grows. The latter, however, is a low procumbent shrub with more densely sericeous twigs and leaves, fewer (11-17) roundish leaflets. Osteomeles boninensis is not as hardy as Osteomeles subrotunda in Tokyo. Of the former there was once a cultivated plant in the Botanical Garden of the Tokyo Imperial University but it died nearly ten years ago.

The specimens sent to the Gray Herbarium from the herbarium of the Botanic Gardens of Petrograd consist of three flowering branches; one being Prunus aequinoctialis var. plena rosea Miyoshi (in Tokyo Bot. Mag., xxxiv. 165 [1920] ) which is a double-flowered form of P. pendule Maxim., and two of this variety. This variety resembles the type of Prunus incisa Thunberg to which Maximowicz has referred it in Bull. Acad. Sci. St. Pétersb. xxrx. 100; in Mél. Biol. x1. 693 [1883] ), but in the type the pedicels are stouter aoe shorter and the calyx-tube is more elongated than in this variety.

rpinia nepalensis Wallich is distinguished from this species by pin- nate (3-9-foliolate) leaves and more hairy inflorescence. Turpinia pomifera De Candolle, too, is distinct, for it has pinnate leaves, more vigorous inflorescence and larger fruits (3-4 cm. in diameter). T'urpinia pomi- fera is an East Indian plant, and 7. nepalensis is distributed over East India, Himalaya, Nepal, China, and the Philippines. There is another new species in China, and one in the Philippine Islands which are described below.

This is nearest to Meliosma Oldhami Miq. but is more glabrous in every respect. The hairs of the leaves are very remarkable; in M. Oldhami the lower surface of the leaves are covered by fine hairs throughout and the axils of the veins are glabrous while in this species the upper surface of the leaves has very short scabrous hairs and the lower surface has none except tufts of brownish hairs in the axils of the main veins.
