瓦韦属植物的系统学研究

根据瓦韦属植物根状茎上的鳞片及隔丝的形状、结构、颜色,参考叶片的形状、质地及根状茎、叶柄的横切面等特征,把瓦韦属植物划分为6个组,分别为瓦韦组Sect．Lepisorus、扭瓦韦组Sect．Pleioomma S．L. Yu、革质叶组Sect．Sclerophyllon S．L. Yu、大叶瓦韦组Sect．MacrophyllonS．L.Yu、纸质叶组Sect．Pachyphyllon S．L.Yu和薄叶组Sect．Hymenophyton Ching。     

中国产瓦韦属植物叶柄与根状茎的比较解剖研究

详细观察了已发表的60种瓦韦属植物叶柄和根状茎的横切面。瓦韦属植物叶柄维管束条数最多7条,最少2条,其中2个较粗,其余较细,排成一字型、三角型、四角型、半轮型等。根状茎上的维管束条数最少5条,最多16条,属于网状中柱,维管束不规则环形排列,夏绿种类厚壁组织较少或没有,常绿种类厚壁组织较多。叶柄与根状茎的研究对瓦韦属组的划分和种的确立有重要的参考价值。参考这些特征,瓦韦属相应地划分成六个组,即:大叶瓦韦组、扭瓦韦组、瓦韦组、革质叶瓦韦组、纸质叶瓦韦组、网眼瓦韦组。一些种类相应地进行了合并。     

Taxonomic revision of Lepisorus （J. Sm.） Ching sect. Lepisorus （Polypodiaceae） from China

The taxonomy of Lepisorus （J. Sm.） Ching sect. Lepisorus in China was revised based on herbarium specimen examinations, field observations, and microscopic study of rhizome scales, soral paraphyses, leaf epidermis, and spores. As a result, nine species were recognized： Lepisorus macrosphaerus （Baker） Ching, Lepisorus asterolepis （Baker） Ching, Lepisorus marginatus Ching, Lepisorus kuchenensis （Y.C. Wu） Ching, Lepisorus megasorus （C. Chr.） Ching, Lepisorus kawakamii （Hayata） Tagawa, Lepisorus subsessilis Ching ＆ Y.X. Lin, Lepisorus affinis Ching, and Lepisorus nudus （Hook.） Ching. Lepisorus kawakamii （Hayata） Tagawa was reinstated; Lepisorus gyirongensis Ching ＆ S.K. Wu and Lepisorus longus Ching were reduced to synonyms ofL. nudus and L. affinis, respectively. The subdivision ofLepisorus macrosphaerus was not accepted. Rhizome scales and paraphyses are the most useful characters for species delimitation as well as for infrageneric classification. Characteristics of the leaf epidermis and spore ornamentation are usually stable and thus of great significance in understanding the relationships among groups within the genus.

On the taxonomy of Phlegmariurus (Herter) Holub sect. Huperzioides H. S. Kung et L. B. Zhang (sect. nov.) with notes on the infrageneric classification of the genus Phlegmariurus in China

After the genus Phlegmariurus (Herter)Holub was proposed by J. Holub 1964, the repercussions are different, with some botanists accepting it, while others refusing. We take it as a separate genus since the related species from China are distinctly different from those of Huperzia Bernh. The plants of this genus in China are classified into three sections: Sect. Huperzioides H. S. Kung et L. B. Zhang, sect. nov.; Sect. Carinaturus (Herter)H. S. Kung et L. B. Zhang, comb. nov. and Sect. Phlegmariurus. A key to sections is given. The taxonomy on the new section, Sect. Huperzioides, is presented. Thirteen species are reported in China, involving 4 new combinations: Ph. petiolatus (Clarke)H. S. Kung et L. B. Zhang, Ph. cryptomerianus (Maxim.)Ching, Ph. ovatifolius (Ching)W. M. Chu, Ph. nylamensis (Ching et S. K. Wu)H. S. Kung et L. B. Zhang; and 7 names are considered for the first time as synonyms: Huperzia formosana Holub [ = Ph. taiwanensis Ching ], H. austrosinica Ching [ = Ph. petiolatus ], Lycopodium mingchgense Ching [ = Ph. mincheensis Ching ], Ph. mincheensis var. angustifolius C. Y. Ma [ = Ph. mincheensis ], Ph. longyangensis C. Y. Ma [ = Ph. fordii ], Ph. nanus C. Y. Ma [ ＝ Ph. fordii ], Ph. yandongensis Ching et C. F. Zhang [ ＝ Ph.fordii]. One new record in China is found: Ph.hamiltonii.

A preliminary study on the classification,distribution and ecological nature of genus Stipa L. of China

24 species and 4 varietes of genus Stipa L. of China have been studied and described in this paper. It has been noted that these different species have various geographical distributions, depending on the changes of climatic and edaphic factors of their environments. Based on the study of floral morphology together with ecological and distributional factors, the genus have been divided into 5 sections: 1. Sect. Regelia Tzvel. 2. Sect. Leiostipa Dum. 3. Sect. Barbatae Junge 4. Sect. Stipa 5. Sect. Smirnovia Tzvel. It should be pointed out that the section Regelia as well as two members of section Barbatae, S. purpurea and S. roborowskyi, belong to frigori-xerophilous ecotype, distributing over Qinghai-Xizang Plateau above the forest line. The section Leiostipa belongs to euxerophilous and mesoxerophilous ecotype, distributing widely in northwest, southwest, northeast and east and extends to the forest-steppe vegetational Zone of China. The section Smirnovia and other two members of section Barbatae, S. breviflora and S. orientalis, belong to euxerophilous ecotype, with the latitudinal distribution as far as Nei-Mongo and the yellow soil plateau, with the altitudinal distribution as far as the desert steppe of Sinkang and Qinghai-Xizang plateau. The section Stipa belongs to euxerophilous ecotype, only distributes to the mountain steppe of north Xingkang and the last, section Barbatae is an artificial group having plumes overof the awn only, and its four species have already been mentioned above.
