苦竹亚族的修订

This paper deals with the taxa of tribe Arundinarieae Steud. subtribe Pleiobalastinae Keng and Keng f. which comprised three genera (Pseudosasa Makino, Pleioblastus Nakai and Brachystachyum Keng) when it was established in 1957. With the analysis of morphological characters and geographical distribution, a number of revisions connected with the taxon are made as follows:      (1)  Genus Brachystachyum Keng is transferred to the tribe Shibataeeae Nakai ac- cording to its false inflorescence.      (2)  Genus Pseudosasa Makino is transferred to subtribe Sasinae Keng f. according to our study on the numerical taxonomic method.      (3)  Some species of Pleioblastus Nakai established by Keng and Keng f. should be revised. Pleioblastus actinotrichus (Merr. and Chun) Keng f. should be Ampelocalamus actinotrichus (Merr. and Chun) S. L. Chen, T. H. Wen and G. Y. Sheng in subtribe Tham- nocalaminae Keng f.; Pleioblastus dolichanthus (Keng) Keng f. is the synonym of Sinobam- busa tootsik (Sieb.) Makino, belonging to tribe Shibataeeae Nakai. The rest species remain in this genus. Since the genus Pleioblastus is related to genus Arundinaria Michaux., subtribe Pleioblastus Keng and Keng f. does not seem to have a reason to be retained as a subtribe in tribe Arundinarieae Steud., according to the newest Code (1978). A part of it should be a synonym of subtribe Arundinariinae and we may cite it as follows: Subtribe Arundinariinae——Subtribe Pleioblastinae Keng and Keng f. pro parte, syn. nov. The other parts of it should be transferred to other subtribes or tribes.       In addition, one new variety in Branchystachyum, two new species, one new variety in Pseudosasa and six new species, three new varieties in Pleioblastus, are described in this paper.

藏香芹属的修订

石笔木的学名考正：Tutcheria championii 还是 T. spectabilis?

为何Tutcheria championii Nakai (1940) 发表较晚, 却被《中国植物志》等志书作为正确学名；而 T. spectabilis (Champ. ex Benth.) Dunn (1908)这更早发表的名称却成了异名？ 笔者在本文解释，根据《国际植物命名法规》，因T. championii这后出替代名发表时曾引用Camellia spectabilis Champ. ex Benth.，而主模式标本因此已包含在内，所以在Tutcheria属内，具相同主模式的T. spectabilis是合法名也具有优先权，应为正确学名。

中国禾本科植物志资料之一，国产柳叶箬属的重订

This paper is here presented as a material for a flora of the Chinese grasses.  At the beginning, it chronologically gives a brief historical sketch on the study of the sub- tribe Isachninae.  The category which this group should constitute is here delimited, and its position in the natural system of grass-classification is also discussed.       Secondly it deals with a taxonomic treatment on the genus Isachne which comprises 16 species and 7 varieties in China, amongst which two species (I. hoi and I. hainanensis) and four varieties (I. albens var. glandulifera, I. truncata vars. crispa & maxima, and I. nipponensis var. kiangsiensis) are published here as new to science.  In addition, a new combination, I. hirsuta, (Hook. f.) Keng, f., based upon I. albens var. hirsuta Hook. f., is made here.  The two species (I. ciliatiflora Keng, and  I. tenuis  Keng)  published in Chinese only in the “Flora Illustralis Plantarum Primarum Sinicarum Graimeae 1959”, arehere supplemented with Latin diagnoses for validation.

菊科莴苣属订正及亚洲大陆菊科植物二新属(续）

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 capitu- lum 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, evident- ly, 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. meridi-  onale 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 combi-  nation 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, establi-  shed 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 ache-  nes, non-marginated.   Lagedium Sojak widely distributes  in temperate  and  frigid  zone  of  northern hemisphere.  In our country, Lagedium sibiricum (L.) Sojak, sole species of the ge- nus, restricts its northeast region.        Paraprenanthes Chang, the new genus, established by Ch. Ch. Chang (1950) based on La- ctuca sororia Miq. and Lactuca yunnanensis Franch.  seems to be a distinct genus.  This ge- nus 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 tro- pic 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 sub- tropic zones on the mainland of Asia.  They are P. sororia (Miq.) Shih, P. yunnanensis (Fra- nch.) 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. sagitti- formis Shih, sp. nov.
