LANCASTER, PA. THE ARALIACEAE OF CHINA! Hur-Lin Li with fourteen text-figures INTRODUCTION This is a systematic study of the Araliaceae of China. An attempt is made to account for every published binomial belonging to this family as recorded from China in botanical literature from 1753 to the present date. Sources of all names are cited and an attempt has been made to clarify the often somewhat complicated synonymy. The work is mainly based on the extensive collection of Chinese plants at the Arnold Arboretum, supplemented by collections from other Chinese and American herbaria. The Araliaceae as a group is particularly difficult to study because of constant problems in relation to the delimitation of many genera and species. As it has been impossible for me to consult certain types preserved in European herbaria, because of war conditions, I have been obliged, in certain cases, to accept current interpretations, and thus certain conclusions must be accepted as tentative. In adopting generic limitations generally accepted by most modern authors, seventeen genera’ are recognized as occurring in China. Among them only Panax and some species of Aralia are herbaceous, all others being ligneous vines, shrubs or trees. Diplopanax is a monotypic genus confined to China. Merrillio- panax, herein described as a new genus from Yunnan, is also represented in India. Tupidanthus occurs also in India, Tetrapanax in Formosa, Heteropanax in tropical Asia, and Kalopanax in Japan. Trevesia, Brassaiopsis, Macropana.x, and Acanthopanax are more or less widespread in southern Asia, while Sche flera, Dendropanax, Pentapanax, and Aralia, as herein interpreted, are common to both hemispheres. Panax is found in temperate regions of eastern Asia and North America, and Hedera in Asia, Europe, and North Africa. Nothopanax is chiefly Australian, with some species occurring in China. Besides a few doubtful ones, a total of 121 species, 32 varieties, and 3 forms are recognized in this study. This number is about seven times that known to Forbes and Hemsley in 1888 (13), and twice the number enumerated by Chung in 1924 (6). The family is most highly developed in genera and in species in the south and southwestern parts of China. The numerous botanical explorations made in recent years in these parts of China by the Fan Memorial Institute of Biology, the Botanical Institute of Sunyatsen University, Lingnan University, and the University of Nanking, all in collaboration with the Arnold Arboretum 1A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Biology, Harvard University. 2 Plerandra (Diplasandra) jatrophifolia Hance (Jour. Bot. 19: 275. 1881) was described from a plant cultivated in the Hongkong Botanic Garden. The genus is Polynesian. As the original habitat of this plant is unknown, this genus is not treated here. Fatsia japonica (Thunb.) Dene. & Planch. is also found only in cultivation in China. I have seen only one single fruiting specimen from China: Chekiang, Hangchow, Chi Pan Shan, Chekiang Univ. LU77622, in LU. 2 SARGENTIA [2 of Harvard University, have greatly enriched our reference collections and thus added to our knowledge of this family. The classification of the Araliaceae has been treated by Baillon (1), Seemann (32, 33), Bentham and Hooker (3), Harms (17), and Viguier (36). In the present work, the systematic order of the genera follows that of Harms in Engler and Prantl, Die Naturlichen Pflanzenfamilien (17). Genera described since Harms’ work was published are placed in accordance with his general arrange- ment. In characterizing the accepted genera, the original descriptions and later ones by other authors have been consulted, and these descriptions have been studied in association with extensive collections of Chinese and other Old World material. On account of the lack of sharp and well defined characters, various authors have at times tended to subdivide larger groups, but it is felt that at least some of those who advocate small generic segregates have lacked accessibility to comprehensive collections of reference material. In this treatment, it has been thought desirable to follow generic interpretations as accepted by most modern authors ; in other words, I have adopted a conservative attitude. It is to be noted that between closely related genera, such as Aralia and Pentapanax, Brassaiopsis and Acanthopanax, etc., species apparently transitional in nature are often found. In cases of doubt or those of special interest, more or less detailed discussions are given under each species. The descriptions of the species herein presented are based on the original diagnoses, supplementary data provided by later authors, and an actual examination of all available specimens. The generic descriptions, in general, have been limited to the characters presented by the Chinese species. In connection with this study of the Chinese Araliaceae, I have found the practice of pasting original descriptions and critical notes in the form of clippings or typed data into the herbarium to be extremely useful. It not only saves time in searching for references in widely scattered literature, but also enables one to detect many bibliographical errors by checking the complete series of assembled data regarding a given species. My study was greatly facilitated by having access to the very large amount of published data incorporated in the Britton Her- barium, New York Botanical Garden, and the less extensive assemblage in the herbarium of the Arnold Arboretum. In both institutions this task of inserting published data in the herbarium was initiated by Dr. E. D. Merrill, in 1930 and 1935 respectively. Where this work has been extensively done, the student con- sulting the herbarium finds a great deal of his needed bibliographical data readily available in juxtaposition with the actual herbarium specimens. For the tech- nique of inserting published data in the herbarium, see Merrill, Jour. Arn. Arb. 18: 173-182. 1937. In the course of this study, it is found desirable to describe some new species and varieties and to make some new combinations; at the same time I have re- duced to synonymy certain species proposed by various authors. One new genus is proposed. The types of the new species and varieties, unless otherwise indi- cated, are deposited in the Herbarium of the Arnold Arboretum, Harvard Uni- versity. It is to be noted that most of the new species are found in Yunnan, with a fair number from Kwangsi. These subtropical regions have been intensively ex- plored only in recent years. Most of the new species are in the genera Sche fflera and Dendropanax, both of which are mainly tropical in distribution. Species of the large and more temperate genera Acanthopanax and Aralia have been col- lected more frequently and are fairly well known. The mountainous south- 1942] LI, THE ARALIACEAE OF CHINA a western parts of China still furnish a wealth of botanical material, with numerous novelties in all major groups of plants. As the floras of the adjacent regions, such as Siam, Burma, and Indo-China are, as yet, imperfectly known, a closer coordination of our knowledge of the elements of these closely related floras is highly desirable for a better understanding of the relationships and geographic distribution of the species occurring within the contiguous areas. HISTORICAL NOTE Three genera of the family Araliaceae were recognized by Linnaeus in 1753 (24). They were placed separately, Aralia in Pentandria-Pentagynia, Hedera in Pentandria-Monogynia, and Panax in Polygamia-Dioecia, in the Linnaean system. Ventenat in 1799 (35) first established the Araliaceae as a family, followed by Jussieu in 1816 (22) and D. Don in 1825 (9). DeCandolle (4) monographed the family in 1830, and later Endlicher (12) treated it in 1840 and Decaisne and Planchon (8) in 1854 respectively. From 1864 to 1868, Seemann (32, 33) revised the whole group by recognizing two ‘orders,’ the Hederaceae, those with flowers having valvate petals, and the Araliaceae, those with flowers having imbricate petals. Later treatments on the classification of the family were by Baillon (1) in 1880, Harms (17) in 1894, and Viguier (36) in 1906. No monographic study of the entire family has been made in recent years. The first species described from China were Aralia chinensis Linn. and Zan- thoxylum trifoliatum Linn. (the basis of Acanthopanax trifoliatus (Linn.) Merr.) published in 1753 (24). Other authors, such as Loureiro (25), Cham- pion (5), Hance (15), Bentham (2), Seemann (32), and others, and later on Franchet (14), Harms (17, 18, 19, 20, 21), and others described many species of Chinese Araliaceae. In 1888, Forbes and Hemsley (13), in their enumera- tion of Chinese plants, recorded nine genera and twenty-two species of Araliaceae, including one species of the genus Helwingia, which is now placed in the family Cornaceae. Since that time a number of new genera and species have been added to the Chinese list as a result of successive botanical explorations in the more remote provinces. In 1924, Chung (6), in his catalogue of Chinese woody plants, listed fourteen genera, seventy-two species, and seven varieties of aralia- ceous plants. This number has since been increased considerably. Among the more recent authors who have contributed most to our knowledge of the Chinese Araliaceae are Handel-Mazzetti (16), Harms (17, 18, 19, 20, 21), W. W. Smith (34), Rehder (21), Merrill (26, 27, 28), and Chun (28). GENERAL AND DIAGNOSTIC CHARACTERS The Araliaceae are for the most part woody plants, Panax and some species of Aralia being herbaceous. The ligneous representatives vary from low shrubs to tall trees or vines, sometimes climbing by means of aerial roots. Some of them are epiphytic or pseudoepiphytic. The herbaceous species are perennial, with fleshy rootstocks. Some of the herbaceous species of Aralia have suffru- tescent stems. Many of the plants are prickly. The length, shape, abundance, and distribu- tion of these prickles are important diagnostic characters. In addition to prickles, the plants may be covered with indumentum ranging from bristles or setose hairs to a well defined tomentum. The hairs may be simple, scaly, furfuraceous, or 4 SARGENTIA [2 more commonly stellate, and in color the indumentum varies from white to brown, ferruginous or red. The leaves are alternately arranged and are sometimes more or less clustered at the ends of the branchlets. They may be simple and entire or palmately lobed, or digitately or pinnately compound or decompound. There are considerable variations in the size, shape, indumentum, serration, etc., and all are important diagnostic characters for delimiting genera as well as species. The number, prominence, and arrangement of the nerves are useful as specific characters in many cases. Some of the species of Dendropanax have characteristic trans- lucent glands in the leaves, which vary in size, color, and distribution. The petioles are generally long and slightly enlarged and thickened at the base. The stipules are either adnate to and scarcely distinguishable from the base of the petiole or prominent, intrapetiolar, and united. They are occasionally absent. The inflorescence is very important in the classification of the genera as well as species. It may be terminal at the end of long or short branches or axillary. The flowers of most species are arranged in umbels, occasionally in racemes. The umbels or racemes may again be organized into compound umbels or panicles. Some species have sessile flowers compactly arranged in globose heads. The inflorescence is frequently covered with indumentum. The number of flowers in the umbels, the length of the peduncles, the shape and size of the bracts and bracteoles, and the length of the pedicels are useful in differentiating some of the species and varieties. The presence or absence of articulations on the pedicels just below the flowers is an important generic character. The flowers are regular, commonly very small, and perfect, polygamous, or dioecious. They are mostly 5-merous, but 4-merous and other variations are found. In Tupidanthus, the number of certain floral parts is indefinite. The calyx is superior, enclosing the ovary. It is usually short, infundibular or cup- shaped, and glabrous or hairy. The margin may be entire or distinctly or indis- tinctly dentate. The petals are inserted at the edge of the epigynous disk. They may be valvate or imbricate in the bud, a character that separates the two tribes of the family that are found in China. They are either free or they may cohere at their tips, thus at times being almost calyptrate and falling together. The petal-bases are generally broad, while their tips may be slightly thickened and incurved. The stamens are generally of the same number as the petals and inserted alter- nately with them, rarely twice as many as the petals or indefinite in number. The filaments are distinct, short, as long as or sometimes slightly longer than the petals. The anthers are oblong or ovate, introrse, versatile, and consist of 2 locules dehiscing longitudinally. The ovary is inferior, with one or more cells. The ovules are solitary in each cell, anatropous, and pendulous from the apex. The ovary is crowned by an epigynous disk or stylopodium which is either flattened or hemispherical and confluent with the styles. The styles correspond in number to the cells of the ovary and are distinct or more or less cohering into a column or short cone, rarely absent. The stigmas are simple, insignificant or slightly capitate. The fruit is a berry or drupe mostly small in size, usually longitudinally ridged and sulcate. The shape, size, number of cells, and other characters are of diag- nostic importance. The fruit is frequently crowned by the persistent styles or style-column and by the calyx-teeth. The exocarp is usually fleshy. The endo- carp is sometimes hardly distinct from the exocarp or forms distinctly carti- 1942] LI, THE ARALIACEAE OF CHINA 5 laginous or membranaceous pyrenes. The seeds are solitary in the pyrenes, in- verted, usually laterally compressed, with a minute straight embryo and a fleshy, copious endosperm. The endosperm may be uniform or ruminated, a character of generic value. SYSTEMATIC POSITION AND SUBDIVISIONS The family Araliaceae is one of the three of the order Umbelliflorae (Umbel- lales), which is generally regarded as the most highly specialized group of the Archichlamydeae. This order is characterized by the commonly umbellate in- florescences and the usually small, epigynous flowers, with generally constant numbers of floral parts. The other two families are Umbelliferae and Cornaceae, the latter sometimes split into more than one family. The Araliaceae and Umbelliferae are considered as phylogenetically closely related, while the Corna- ceae is not very closely allied to the other two. The Araliaceae differs from the Umbelliferae in that its habit is prevailing woody, the carpels 1-5 or sometimes more, and the fruit a drupe or berry; in the Umbelliferae the plants are all herbaceous, the carpels invariably two in number, and the fruit is a schizocarp. The Chinese genera of Araliaceae can be arranged in two very clearly distinct tribes, the Schefflereae and the Aralieae. The former has the petals valvate in the bud, and the latter has imbricate petals. A third tribe, the Mackinlayeae, has no representative in China. RELATIONSHIPS OF THE CHINESE GENERA Tupidanthus is unique in the Araliaceae and seems to be only remotely related to the other genera. Its primitiveness, however, as indicated by the numerous stamens, ovary-cells, and styles, is unquestionable. By reduction in the number of its floral parts, its ancestral form may have evolved toward such a genus as Plerandra, an Indo-Polynesian genus, and thence on to other genera of higher positions. Among the other genera, Trevesia is one of those of a more primitive nature, but in its 7-12-merous flowers it is distinctly more advanced than Tupidanthus. Nevertheless, it is still more primitive than the other genera in its more numerous petals, stamens, and ovary-cells. Reduction in the number of floral parts is a definite and clearcut sequence of evolution in this family. Tetrapanax may be the result of further reduction from Trevesia. All of the three genera mentioned, Tupidanthus, Trevesia, and Tetrapanax, have a uniform endosperm, digitately lobed or palmately compound leaves, inarticulate pedicels, and entirely umbellate flowers. Schefflera may represent a center of development culminating at this level. This large genus has closely related species, but variations within the genus are already manifest in the several directions that eventually lead to the development of other genera. The number of petals, stamens, and ovary-cells in the Chinese species varies from 5 to 7. The flowers, although mostly in umbels, are some- times capitate or racemose ; where the flowers are umbellate the umbels are often arranged in racemes. The leaves are prevailingly digitately compound in the Chinese species, but in certain extra-Chinese species they may be simple. The endosperm is mostly uniform, but in a few cases slight ruminations are present. Those species of Schefflera with capitate flowers and ruminate endosperm point to the development of such a genus as Oreopanax. Those with ruminate 6 SARGENTIA [2 endosperm, by further reduction especially in the number of ovary-cells, may lead to the development of such a genus as Brassaiopsis, a group which is also appar- ently related to certain species of Acanthopanax. There may also be relation- ships between some species of Brassaiopsis and Tetrapanax and other genera with palmately lobed leaves. On the other hand, Dendropanax, also apparently close to Schefflera, may have been evolved from the latter by a reduction of its vegetative parts, as it always has strictly simple leaves. Hedera is apparently derived from Dendropanax, but is more specialized in its climbing habit, often dimorphous leaves, and ruminate endosperm. The true alliances of Diplopanay are somewhat doubtful, as its single-celled ovaries, spicate inflorescences, and unique fruits are all outstanding and indicate little relationship to the other genera discussed. It is apparently closer to Dendropanax or perhaps Schefflera than any of the other genera. Acanthopanax is another large group that may have been a center from which other genera have been derived. It represents a higher level than Schefflera, as evidenced by its smaller number of floral parts and the slight articulation of the pedicels in certain species. The genus is heterogeneous and may ultimately require certain segregations. Some species of Acanthopanax are apparently related to Brassaiopsis, parti- cularly those species with a reduced number of ovary-cells. The articulation of the pedicels is further developed in Nothopanax and Macropanax, the latter being further specialized by its ruminate endosperm. Merrilliopanax may represent another line of specialization from Acanthopanax, particularly in the direction of Nothopanax. Kalopanax, which has been included in Acanthopanax by some authors, is unquestionably closely related to the latter. It 1s, however, possibly equally close to Brassaiopsis, for some species of Brassaiopsis may have been Panax ff y \ Macropanax / Aralia . 9 Z Ne Nothopanax \. / rq ™ / Pentapanax | | se / i athe 9 57 .

The different genera so far discussed are all members of the tribe Schefflereae, characterized by having valvate petals. They bear either simple or palmately lobed or digitately compound leaves. Heteropanax, however, differs from all others in having pinnately compound or decompound leaves. In floral char- acters, it is close to Brassaiopsis and Macropanax. It may represent a highly specialized line derived out of some genera with pinnately lobed leaves, that are not at present represented in China. The tribe Aralieae has imbricate petals and evidently represents a higher devel- opment than the tribe Schefflereae, as evidenced by the herbaceous habit in some of the species. Pentapanax is even more primitive than Aralia, as may be judged by its prevailingly woody habit and generally more numerous ovary-cells. Pana+ is entirely herbaceous and represents a more specialized development. Its digi- tately compound leaves, however, indicate little relationship with the other two genera with pinnately compound leaves and it may even be remotely connected with Acanthopanax or other genera of the tribe Schefflereae. A schematic representation of the relationships of the Chinese genera is pre- sented on p. 6 to summarize the above discussion. The extra-Chinese genera mentioned are indicated by their names being in parentheses. Solid lines indi- cate more definite relationships, while broken lines indicate doubtful ones. Ar- rows are used to show probable directions of evolution. GEOGRAPHICAL DISTRIBUTION The family Araliaceae is mainly tropical, with very few of its genera extending to the north. In China the maximum development is in the southwest, with the province Yunnan yielding over half of all the known Chinese species. It is well represented in all the southern provinces, with 30° N. as the northern boundary of most of its genera. Among the seventeen genera known to occur in China, only five, Acanthopanax, Kalopanax, Aralia, Hedera, and Panax, have species that extend to the Yellow River Valley or occasionally even as far north as Manchuria. The distribution of the different genera may be summarized briefly as follows: 1. Tupidanthus. This monotypic genus is found in India and Burma. In China it is known from Yunnan only. 2. Trevesia. The one species and variety of this genus found in southwestern China occur in the provinces Yunnan and Kweichow. This genus is widespread in tropical Asia. 3. Tetrapanax. A single species of this genus occurs in southern and western China, in the provinces Hunan, Szechuan, Yunnan, Kweichow, Kwangsi, and Kwangtung. It has also been recorded by other authors from Anhwei and Hupeh. Outside of China it occurs in Formosa only. 4. Scheffilera. This large genus is common to the warmer parts of both hemi- spheres. Twenty-eight species and two varieties are recorded in the present study. Yunnan is the chief center of occurrence in China, with twenty-two species. From five to seven species are found in each of the provinces Kweichow, Kwangsi, and Kwangtung, and one to three in Chekiang, Fukien, Hainan, Kiangsi, Szechuan, and Sikang. 5. Diplopanax. This recently established monotypic genus is endemic in Kwangsi. 8 SARGENTIA [2 6. Dendropanax. This genus is common to the tropical regions of Asia and America, a few species extending beyond the tropics. It is essentially tropical and southern in China. Of the thirteen species and one variety found in China, eleven are recorded from Kwangsi, nine from Kwangtung, three from Hainan, and three from Kweichow. One or two are found in each of the following provinces: Fukien, Yunnan, Szechuan, Hunan, Kiangsi, Anhwei, and Chekiang. In China this genus extends to about 30° N., but it occurs north of this in Korea and Japan. 7. Hedera. This genus is found in Asia, Europe, and North Africa. The one variety found in China is fairly widespread. It is found mainly in western China from Kansu and Shensi in the north to Yunnan in the south and along the Yangtze Valley in central and eastern China. 8. Brassaiopsis. This is a tropical genus which extends from India to Malaysia. In China it is entirely confined to the southwestern part of the country. Of the thirteen species, almost all are found in Yunnan, while a few extend to the neighboring provinces, such as Szechuan, Kweichow, Kwangsi, and Hainan. 9, Macropanax., The two species of Macropanax are mainly characteristic of India. In China they are found in Yunnan and Hainan only. 10. Merrilliopanax. This new genus contains two species. One of them is common to northeastern India and Yunnan. The other is known from a single Yunnan collection. 11. Nothopanax. This genus is chiefly Australian.. The three Chinese species are localized in the southwest, mainly in Yunnan, but the group is also repre- sented in Hupeh, Szechuan, Sikang, and Kweichow. 12. Acanthopanax. ‘This large eastern Asiatic and Himalayan genus is distinctly temperate in distribution and is well represented in all parts of China. It is found in all provinces from Manchuria south to Hainan Island, with the maxi- mum development along the Yangtze Valley. Twenty-two species, twelve varie- ties, and three forms are recorded in this study. These are more or less evenly distributed throughout the different provinces. Ten or more are found in both Yunnan and Szechuan (including Sikang). About five species and varieties are found in each of the following provinces: Shensi, Kansu, Hopei, Chekiang, Anhwei, Kiangsi, Kwangsi, Kwangtung, and Kweichow. The other provinces have from one to three each. 13. Kalopanax. The single species (with two varieties) of this genus is wide- spread in China. Records are found in all provinces from Manchuria to Kwang- tung except Hainan and Kwangsi in the south and Kansu and Shensi in the north. It also occurs in Japan. 14. Heteropanax. The three species and two varieties so far known in this genus are found in the southern provinces, Kiangsi, Yunnan, Kwangsi, Kwang- tung, and Hainan. The genus is southern Asiatic in distribution. 15. Pentapanax. ‘This genus occurs in southern Asia, Australia, and in tropical America. Seven species and one or two varieties are known in China. They are all confined to Yunnan except one or two from Szechuan, Sikang, and Anhwei. 16. Aralia. This large genus is characteristic of the temperate and tropical regions of Asia and America. Twenty species and two varieties are known in China. The genus is widely distributed all over China from Manchuria to Hainan. The species are especially well dispersed in the provinces along the Yangtze River and south to it. The maximum development is in Yunnan, Kwangtung, and Kwangsi. 1942] LI, THE ARALIACEAE OF CHINA 9 17. Panax. This genus is found in the temperate regions of eastern Asia and North America. Of the two species known in China, one is probably confined to Manchuria, while the other, with its several varieties, is found mainly in southern, western, and central China. ECONOMIC USES The family Araliaceae yields a number of important drug plants. The ginseng, Panax schin-seng Nees, is a very famous Chinese tonic. The root bark of Acanthopanax gracilistylus W. W. Smith, its varieties, and possibly some of the related species, known as wu-chia-pi, is used in making a well known medicinal wine. The root of Aralia cordata Thunb., and the stems, leaves, and fruits of Hedera nepalensis var. chinensis Rehder are also used in Chinese medicine. The pith of Tetrapanax papyriferus Koch produces the rice paper, tung-tsao, which is used in medicine and is very extensively employed in making artificial flowers and for other purposes of decoration. A number of timber trees are found in this family. Kalopanay pictus (Thunb.) Nakai is an important timber tree in China. It is widely scattered and common throughout most parts of China. A few species, such as Schefflera octophylla Harms, produce lumber that is used for making furniture and for other purposes. Many shrubs, particularly those of the genera Acanthopanax, Nothopanax, and Aralia, are valued as ornamentals. NOMENCLATURE AND CITATIONS In this treatment, Panax and all Panax compounds are treated as masculine, as this is provided for specifically in the last edition of the International Rules of Botanical Nomenclature. Panax classically is masculine, but Linnaeus (24) used it as neuter. Most botanists did the same until Franchet in 1886 and Harms in 1894 (17) consistently used the masculine form for Panax and all the Panax compounds; this latter usage is correct and should be universally adopted. The citations of specimens at the end of the descriptions are given in chrono- logical order. The dates of the specimens cited are omitted to conserve space. Series numbered by institutions are cited after the collector whenever the collector is indicated on the labels. Geographic subdivisions are based on provinces, with Hainan separated from Kwangtung. They are generally given in the following order: Kansu, Shensi, Shansi, Honan, Hopei, Jehol, Manchuria, Shangtung, Kiangsu, Chekiang, Anhwei, Kiangsi, Hunan, Hupeh, Szechuan, Sikang, Tibet, Yunnan, Kweichow, Kwangsi, Kwangtung, Hainan, and Fukien, beginning from the northwest along the Yellow River, extending to the east and then along the Yangtze River to the west and finally along the Pearl River, ending in the south- east. In this sequence phytogeographically related provinces are generally held together. Precise localities are given according to what data are available in the field notes. However, no attempt is made to standardize the local place names, as Chinese characters are mostly not available. Sikang, recently established as a province, was formed from the special District of Sikang and parts of western Szechuan. In many instances it has been considered expedient to enumerate plants from Sikang and Szechuan together, as from the place names originally given in the field notes it is often difficult or impossible to make out their exact locations according to the new provincial boundaries. Some doubt may thus be 10 SARGENTIA [2 found in places quoted as southeastern Tibet, western Szechuan, and northern Yunnan.

Lastly I am indebted to the curators of the several herbaria listed above, who courteously loaned material for this study. Particular thanks are due to Dr. H. A. Gleason, Curator of the Herbarium of the New York Botanical Garden, for his generosity in loaning not only all the eastern Asiatic herbarium specimens of Araliaceae, but at the same time permitting me to borrow all the specimen covers with the majority of published items appertaining to the Asiatic species of the family actually in place in the herbarium. ARALIACEAE Calyx-tube adnate to the ovary, the margin undulate or denticulate. Petals 5-10, valvate or imbricate, usually free, sometimes connate or calyptrate. Sta- mens usually as many as the petals and alternate with them, or twice as many as the petals, or indefinite, inserted with the petals at the edge of the disk, the fila- ments filiform or ligulate, the anthers oblong or ovate, versatile, introrse, the locules 2, longitudinally dehiscent.

ADDITIONAL DISTRIBUTION: India. The leaves are variable in size and shape. C. B. Clarke (in Hook. f. FI. Brit. Ind. 2: 732. 1879) distinguishes the form with palmate leaves and entire-winged petiolules as var. cheirantha, which is also recorded from China by Hemsley (Jour. Linn. Soc. Bot. 34: 476. 1899). Rock 2402 and Wang 76594 are inter- mediate in the general shape of the leaves between the variety, represented by such specimens as Henry 11757 and Wang 76744, and the typical form. Thus the status of Clarke’s trinomial is questionable and his variety is not accepted as appertaining to Chinese forms. The material from Kweichow has the leaves generally smaller, more coriaceous, and with margins more lobulate than those of the specimens from other regions. 14 SARGENTIA 2 la.

Flowers in umbels, racemes, or globose heads, these arranged in panicles or com- pound racemes, the bracts hairy, deciduous or persistent, the pedicels not articu- lated under the flower. Calyx-margin entire or 5-dentate. Petals 5-7, valvate. Stamens as many as petals, the anthers ovate. Ovary 5-7-celled, rarely less. Styles united into a column or none, the stigmas distinct, sometimes sessile. Fruit globose or ovoid, 5—7-seeded, angled or not; seeds laterally compressed ; endosperm uniform or slightly ruminated. Between 300 and 400 species widely distributed in the tropics of both hemi- spheres. Type species: Schefflera digitata J. R. & G. Forst. of New Zealand. The name Schefflera is now generally accepted by most authors for species of both the Old and New World tropics. While some authors continue to retain some of the subdivisions, such as Heptapleurum Gaertn., as of generic rank, the characters are such that for practical purposes it seems best to retain Schefflera in the wider sense. Attention is called to the fact that Sciodaphyllum P. Br. is the oldest valid name for this group, it having been based on specimens from Jamaica. Since it seems to be desirable to unite all species in a single more or less collective group, the name Schefflera should be conserved, as it is very well known and extensively used. For a consideration of the matter, see A. C. Smith, Trop. Woods 66: 3. 1941. . Key To SPECIES AND VARIETIES - A. Flowers sessile or short-pedicellate, arranged in compact heads. (Section I.

Inflorescence in a terminal panicle, 30 cm. long, densely tomentose, the lateral branches to 15 cm. long, the flowers subsessile or short-pedicellate, attached to the tip of the peduncle among a group of small hairy bracteoles, in compact globose heads, the heads 1.4 cm. across, terminal or few racemosely arranged on the branches, the peduncles 2 cm. or more long, spreading, the bracts caducous. Calyx densely tomentose, the margin subentire. Petals 5, densely tomentose outside, glabrous inside. Sta- mens 5. Ovary 5-celled, the styles 5, erect, connate below. Fruit subglobose, angular, 5-celled, sparsely tomentose to glabrous, about 5-6 mm. across, the pedicels 3-5 mm. long, tomentose, the disk small, 2.5 mm. across, the styles 5, united halfway below and radiating and reflexed above, the endosperm ruminate. YuNNAN: Szemao, Henry 12939 (1sotypr, NY, W) ; Shang-pa, H. T. Tsai 59089 (AA). Dunn describes this as a species of Oreopanax, a genus confined mainly to tropical America. This plant, together with Schefflera Wangii Li, differs from other Chinese species of Schefflera in having globose heads of compactly ar- ranged short-pedicellate fruits. In my judgment, these two species belong to Schefflera rather than to Oreopanax, in spite of the fact that the endosperm in both cases is ruminate, as noticed by Dunn for S. chinensis. Though the endo- sperm of Schefflera is generally considered as uniform, I have found certain other species, such as S. Bodinieri (Lévl.) Rehder, having slight ruminations. The endosperm of the two species under discussion is only slightly ruminate.t In these characters and in general habit, these two species clearly belong to the genus Sche filera. Schefflera chinensis and S. Wangii are related to S. cephalota (Clarke) Harms of India and Malacca, but differ from it in the slender petiolules, the presence of bracteoles in the heads, and the smaller disks. Henry mentions having col- lected only small leaves. The specimens at the herbarium of the New York Botanical Garden, although bearing the same number as those at Kew (photo- graphs by R. C. Ching in NY), are under different labels and may represent distinct collections. Dunn states that the leaflets are entire, but I note that most of them are remotely serrulate, which is also borne out by the photographs of the Kew specimens taken by Ching. Tsai 59089 is a young flowering specimen with 2 leaflets measuring 30 X 16 cm. The margins are entire and revolute. Description of the flower given above is based on this specimen. 2.

Yunnan: Shun-ming Hsien, C. W. Wang 71952 (AA); Cheng-kang Hsien, C. W. Wang 72364 (typr, AA), March 1936. This species is closely related to S. chinensis (Dunn) Li, which differs from other Chinese species of the genus in the fruits being arranged in compact heads. It can be distinguished from the latter by its seven leaflets with entire margins, more ascending lateral nerves, and tertiary veins conspicuous beneath ; the leaflets are generally broadest above the middle. Moreover, the heads are smaller and with fewer fruits, and arranged in subterminal racemes. In the other species, the heads are arranged in a large terminal panicle with the branches mostly com- pound. Wang 71952 is similar to the type except that some of the leaflets have a few deep incisions and are somewhat less pubescent beneath. 3. Schefflera hypoleucoides Harms, Rep. Sp.

ADDITIONAL DISTRIBUTION: From Indo-China to Formosa and the Liukiu Archipelago. The leaves of this species are sometimes very variable. The ovary is generally 5-celled, but variations between 6-8 cells are not infrequent. The styles are united into a very short but distinct column. Occasionally a few flowers are developed on the peduncles under the umbels and the umbels imperfectly formed, illustrating the transition from a racemose arrangement to an umbellate one. 5.

The Chinese specimens agree well with the available Indian material except that the leaflets are generally sparsely pubescent to glabrescent and sometimes glaucous beneath. As a group, the Chinese plants may deserve varietal standing to sep- arate them from the Indian ones. More material is needed for this decision. 8. Schefflera producta (Dunn) Viguier, Ann. Sci. Nat.

ADDITIONAL DISTRIBUTION: India to Indo-China. Schefflera venulosa (Wight & Arn.) Harms is considered to be a synonym of S. elliptica (Bl.) Harms by C. B. Clarke, Handel-Mazzetti, and Rehder, the type of the latter being from Java (Sciadophyllum ellipticum Bl. Bijdr. 878. 1826). Craib, in his consideration of the Siamese species of Schefflera (FI. Siam. Enum. 1: 798. 1931), considers that the two species are distinct, and after comparing our Asiatic and Javan material I am convinced that he is correct. The Chinese material certainly represents the same species as the Indian form originally described by Wight and Arnott and as illustrated by Wight. It differs from the Javan species, S. elliptica, in the numerous umbels which are racemosely arranged on the elongated 10-15 cm. long panicle branches, while in Javan material the umbels are few in number and are subcorymbosely arranged on the rather short panicle branches. The typical form of S. elliptica (Bl.) Harms is excellently illustrated by Keorders and Valeton, Atlas Baumart. Java 4: t. 688. 1916.
