Genera Nova vel Minus Cognita Familiae Compositarum,I. Vladimiria Ilj., Diplazoptilon Ling et Dolomiaea DC.

The present paper concerns itself with three Composite genera of the tribe Cynareae (subtribe Carduinae), Vladimiria Ilj., Diplazoptilon Ling and Dolomiaea DC., all ranging throughout the Sino-himalayan region, These genera have in the past always been as sociated with the Eurasiatic genus Jurinea Cass., though there is hardly anything that can indicate such a relationship. Jurinea, according to the conception of Iljin, is a clearly deliminated natural genus, while the three genera now in question are all closely allied to Saussurea DC., being quite remote from Jurinea in the corolla forms, the structure of receptacle and pappus, and also in the morphology of pollen grains. Vladimiria was founded by Iljin, based on Jurinea salwinensis Hand.-Mzt. The genus is a close relative of Saussurea from which it differs chiefly in the usually many seriate pappus which are composed of scabrous or partly barbellulate bristles. As a re sult of our study, a tentative scheme of classification is here proposed, in which Iljin's original generic concept has been amplified to include a dozen of species previously re ferred to Jurinea by Franchet, Diels, Anthony and Handel-Mazzetti from the flora of south-western China and adjacent countries. Two sections, namely, sect. Sorocephalos Ling and sect. Vladimiria (Saussurea sect. Carduella Franch., Mazzettia Ilj.), are being proposed. Diplazoptilon, a new monotypic genus based upon Jurinea picridifolia Hand.-Mzt., is here proposed. It occupies an intermediate position between Vladimiria and Saussurea with a closer affinity to the former, from both of which it is, however, distinguished chiefly by the biseriate pappus with equal plumose bristles. Dolomiaea, a natural genus early founded by De Candolle on the basis of the Himalayan D. macrocephala DC., was considered by Bentham and Hooker f. as not different from Jurinea, a treatment having being followed since by most botanists of the past. But, as mentioned above, its relationship with Saussurea is obvious. It seems to differ from that genus in the two to many seriate pappus, consisting of numerous barbellulate bristles, and in the short style branches. In view of its affinity with Saussurea rather than with Jurinea, the generic status of Dolomiaea should be maintained accordingly. As construed above, the genus is now represented by about 5 species, most of which werepreviously referred to Jurinea by different botanists.     

Taxonomic Study on Genera of Tribe Lactuceae (Compositae) from China

The Present paper is a preliminary result of study on three genera, Dubyaea, Syncalathium and Soroseris of the tribe Lactuceae (Compositae) in China. The genus Dubyaea in China so far known consists of 14 species, of which six are described here as new: D. pteroponda Shih, D. lanceolate Shih, D. muliensis Shih, D. panduriformis Shih, D. cymiformis Shih and D. jinyangensis Shih. In addition, one new combination, i.e.D. bhotanica (Hutch.) Shih, is made. There are six species in the genus Syncalathium in Chinese flora, of which one species is described here as new. This is S. orbiculariforme Shih. A new combination, S. pilosum (Hand.-Mazz.) Shih, is made in the paper. The genus Soroseris comprises nine species, of which three are described here as new, S. teres Shih, S. chrysocephala Shih and S. qinghaiensis Shih. Three new combinations, i.e.S. trichocarpa (Franch.) Shih, S. hirsuta (Anth.) Shih, and S.erysimoides (Hand.-Mazz.) Shih are made in the present paper.

A Revision of Ajania potaninii ( Krasch.) Poljak. Group (Compositae)

In 1983, in Flora Reipublicae Popularis Sinicae 76 (1) Ajania potaninii (Krasch.) Poljak. was treated broadly by the present author. At that time, Chrysanthemum potaninii (Krasch.) Hand.-Mazz. var. amphiseriaceum Hand.-Mazz. , Chrysanthemum truncatum Hand. -Mazz. and Ajania hypoleuca Ling in shed were treated as synonyms of Ajania potaninii (Krasch.) Poljak. Evidently, the treatment of the three taxa was not suitable. It seems neccessary to make further revision in the present paper. Abovementioned three names treated as synonyms should be regarded as three different species of Ajania. However, these three species are closely related to Ajania potaninii (Krasch.) Poljak. They are keying as follows: 1. Leaves undivided. 2. Leaves discolour, green, glabrous above, cinereous-white, densely white-tomentose beneath ............................................. 1. Ajania potaninii (Krasch.) Poljak. 2. Leaves concolour on both sides, cinereous-white, densely white-tomentose ......... ................................................ 2. Ajania amphiseriacea (Hand. -Mazz. ) Shih 1. Leaves pinnatipartite or pinnatisect. 3. Leaves pinnatipartite, discolour, green, glabrous above, cinereous-white, densely white-tomentose beneath ....................................... 3. Ajania hypoleuca Ling 3. Leaves pinnatisect, concolour on both sides, cinereous-white, densely white-tomen- rosa ............................................. 4. Ajania truncata (Hand.-Mazz. ) Ling     

Notulae de Plantis Tribus Cynarearum Familiae Compositarum Sinicae (II)(Cont.)

Since the 19th century many botanists have studied the Chinese Cirsium and a great number of taxa or names has been reported, of which many still need to be reviewed critically This work is a preliminaxy result of study on Chinese species of Cirsium. As many as 65 taxan or names in the literature are reduced to synonym in this paper. The Cirsium in China so far known comprises 49 species, of which 9 are described as new, 1 is a new combination and 4 are new records in Chinese flora. These new species are: C. subulariforme Shih, S. muliense Shih, C. fanjingshanense Shih, C. periacanthaceum Shih, C. racemiforme Ling et Shih, C. vernonioides Shih, C. chrysolepis Shih, C. tenuifolium Shih and the new combination is C. viridifolium (Hand. -Mazz.) Shih. The new records in China are C. serratuloides (L.) Hill., C. incanum (S. G. Gmel.) Fisch. ex MB., C. lanatum (Roxb. ex Willd.) Spreng and C. alatum (S. G. Gmel) Bobr. The Chinese Cirsium is divided into 8 sections in the present paper, of which 3 are new, namely, Sect. Isolepis Shih, Sect. Tricholepis Shilh and Sect. Hymenolepis Shih, and I is a new combination, namely, Sect. Spanioptilon (Cass.) Shih. In addition, a new species of the genus Alfredia, A. aspera Slih, is described.     

Xizangia bartschioides (Hand.-Mazz.) D. Y. Hong,a new combination in Scrophulariaceae

Evidence is provided in the present article to confirm the generic status of Xizangia. This genus is distinctly different from Pterygiella in having rhizomes with winter buds, serrate leaves, unequally cleft calyx (up to 2/3 in length at anterior), and bubblelike and smooth seed-coat. A new combination, Xizangia bartschioides (Hand.-Mazz.) D. Y. Hong is thus made, and Xizangiaserrata D. Y. Hong and Pterygiella bartschioides Hand.-Mazz. are treated as synonymy.     

Revision of Lactuca L. and Two New Genera of Tribe Lactuceae (Compositae) on the Mainland of Asia (Cont.)

Having mixed extremely various patterns of achenes for a long time in the genus Lactuca L., especially showed in the classification of it on the mainland of Asia, Lactuca L., the primary unnatural genus, becomes more nuclear in its limit. The present paper makes a revision to attempt providing a clear cline between Lactuca L. and its relative genera. On my opinion, only plants, represented by Lactuca sativa L., which have ovoid capitulum during its fruiting, numerous (7-25), yellow ligular florets and longitudinal 1-10 ribs or striae on each side of achenes, acute into filiform beak at its apex, should be defined as Lactuca L. In view of the present concept of Lactuca L., another group of plants, embodied by Lactuca indica L., having its broadening, thin winged-margin of, 1-3 striae on each side of achenes, black, dorsi-ventral compressed, acute into thick and short beak at its apex, evidently, should not be placed into Lactuca L., but be regarded as genus, i.e. Pterocypsela Shih, gen. nov. Pterocypsela Shih distributes in Eastern and southern Asia, where Lactuca L. does not occur. In China there is all of species, seven species, of Pterocypsela Shih. They are P. raddeana (Maxim.) Shih, P. indica (L.) Shih, P. elata (Hemsl.) Shih P. lacciniata (Houtt.) Shih, P. triangulata (Maxim.) Shih, P. sonchus (Lévl.) Shih and P. formosana (Maxim.) Shih, But in Mediterranean regions and Middle and Western Asia mainly distributes Lactu ca L., in which there are only seven species from western China, Xijiang autonomic district. They are L. dolichophylla Kitam., L. sativa L., L. altaica Fisch. et Mey., L. serriola Torner, L. dissecta Don, L. auriculata DC. and L. undulata Ledb. With the combination of violet-purple ligular florets non-ovoid capitulum during its fruiting, a little thick achenes, acuminate into longer. or short beak at its apex and 4-6 ribs on each side of it, Mulgedium tataricum (L.) DC. is evidently different from Lactuca sativa L. with combination of ovoid capitulum during its fruiting, yellow ligular florets and compres sed achenes, acute into filiform beak at its apex. There seems to be no point in refusing Mu lgedium Cass. as a genus. Strictly speak, Mulgedium Cass. seems to be reminiscent of Para prenanthes Chang (see bellow) without beak at the apex of its achenes. In Hengduan moun tains and mountain range of Himalayas M. tataricum (L.) DC. discoveries its relative par tners. They are M. bracteatum (Mook. f. ex. C. B. Clarke) Shih, M. lessertianum (Wall. ex C. B. Clarke) DC., M. monocephalum (Chang) Shih, M. umbrosum (Dunn) Shih, M. meridionale Shih and M. polypodifolium (Franch.) Shih. Having broadering and thickening margin and 4-7 striae on each side of achenes, grey, dorsi-ventral compressed, truncate and beakless at its apex, Lactuca sibirica (L.) Benth. ex Maxim. (Sonchus sibiricus L.) is not only different from Lactuca sativa L. with the combination of yellow ligular florets and filiform beak at apex of its achenes, but also from the genus Mulgedium Cass. with beak at apex of its achenes. Therefore, Lagedium Sojak, established by J. Sojak (1961), should be restored. It should be point out that Lagedium Sojak is monotypic genus excluding Mulgedium tataricum (L.) DC. with beak at the apex of its achenes, non-marginated. Lagedium Sojak widely distributes in temperate and frigid zone ofvnorthern hemisphere. In our country, Lagedium sibiricum (L.) Sojak, sole species of the genus, restricts its northeast region. Paraprenanthes Chang, the new genus, established by Ch. Ch. Chang (1950) based on Lactuca sororia Miq. and Lactuca yunnanensis Franch. seems to be a distinct genus. This genus is characterized by 4-6 ribs on each side of achenes, black, fusiform, a little thick and beakless at its apex. Besides above-mentioned two species, assigned by Chang, in forest of tropic and subtropic zones on the mainland of Asia there are many species with same structure in achenes like L. sororia Miq. and L. yunnanensis Franch. The genus Paraprenanthes Chang seems to be reminiscants of Mulgedium Cass. and Lagedium Sojak, but differs from the former in its beakless achenes, from the later in its non-marginated achenes and 4-6 ribs on each side of it. In our country, there are all species of the genus known in the tropic and subtropic zones on the mainland of Asia. They are P. sororia (Miq.) Shih, P. yunnanensis (Franch.) Shih, P. longiloba Ling et Shih, sp. nov., P. heptontha Shih et D. J. Liou, sp. nov., P. prenanthoides (Hemsl.) Shih, P. pilipes (Migo) Shih, P. thirionii (Lévl.) Shih, P. sylvicola Shih., sp. nov., P. multiformis Shih, sp. nov., P. auriculiformis Shih, sp. nov. and P. sagittiformis Shih, sp. nov.     

Xizangia bartschioides (Hand.-Mazz.) D. Y. Hong——玄参科一新组合

虽然玄参科的马松蒿Xizangia serrata D．Y．Hong与齿叶翅茎草Petrygiella artschioides Hand．-Mazz．系同物异名,但齿叶翅茎草与翅茎草属其余4种植物在习性、叶、花萼等外部形态上有显著差异,在种皮方面的差异尤为突出。马松蒿属Xizangia 作为属的地位是合适的。因此,本文作了一个新组合,即XI-zangia bartschioides(Hand．-Mazz．)D．Y．Hong,而把Ptertrygiella bartschioides Hand．-Mazz．和Xizangia serrata D．Y. Hong均作异名处理。

四川乌头属的修订

四川是我国乌头属Aconitum L.植物的重要分布区。本文对该地区的乌头属植物进行了分类修订。通过文献查阅、野外观察和标本室研究,对乌头属的形态性状在居群间和居群内的变异式样进行了比较分析,发现叶分裂程度、上萼片的形状和花梗毛被等性状是较为可靠的分种依据,但是在个别情况,这些性状也会在同一种的同一居群内或不同居群间发生变化。花瓣和种子的特征对于属下划分有重要意义。本文承认四川乌头属植物有46种11变种,另有2种和1变种暂存疑。29种和22变种降为异名;作出新组合2个,其中包括1个改级新组合。紫乌头A. delavayi Franch.和保山乌头A. nagarum Stapf为四川新分布记录。对康定乌头A. tatsienense Finet &; Gagnep.、川鄂乌头A. henryi Pritz.和狭裂乌头A. refractum (Finet &; Gagnep.) Hand.-Mazz.进行了后选模式的标定。初步澄清了东俄洛乌头A. tongolense Ulbr.和狭裂乌头等种类中长期存在的名实混乱。还给出了各个种的形态描述、地理分布以及分亚属、分系和分种检索表。
