黑轴凤丫蕨复合群的分类修订

凤丫蕨属(Coniogramme Fée)种间界限模糊,存在过渡类型,是蕨类植物中分类比较困难的类群之一。黑轴凤丫蕨(C.robusta(H.Christ) H.Christ)是凤丫蕨属植物中比较特殊的种类之一。本文在标本考证、野外考察和微形态研究的基础上对该种的分类进行了订正。将假黑轴凤丫蕨(C.pseudorobusta Ching et Shing)和新黑轴凤丫蕨(C.neorobusta Ching et Shing)归并到黑轴凤丫蕨。同时对该种下的两个变种黄轴凤丫蕨(C.robusta var. splendens Ching et Shing)和棕轴凤丫蕨(C.robusta var. rependula Ching et Shing)重新定义模式标本。     

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.

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, L. asterolepis (Baker) Ching, L. marginatus Ching, L. kuchenensis (Y. C. Wu) Ching, L. megasorus(C. Chr.) Ching, L. kawakamii (Hayata) Tagawa, L. subsessilis Ching & Y. X. Lin, L. affinis Ching and L. nudus (Hook.) Ching. Lepisorus kawakamii (Hayata) Tagawa was reinstated; L. gyirongensis Ching & S. K. Wu and L. longus Ching were reduced to synonyms of L. nudus and L. affinis respectively. The subdivision of L. macrosphaerusis 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.

Taxonomic revision of and supplement to the Tectaria Cav. (Aspidiaceae) from Yunnan,China

Tectaria Cav. is a large fern genus of ca. 150 species distributed in the tropic and subtropic regions of the world, of which 27 species and two varieties occur in China. These species are mostly distributed in the southern part to the Yangtze River, mainly concentrated in Yunnan, only two species spreading northwards to Sichuan located in the northern part to the Yangtze River. Based on examination of specimens deposited in KUN and PE, many of which are recent collections, a new species is described, one species and one variety are recognized as new records for China, one species as new record for Yunnan, one species as new record for Guizhou, and four specific names, i. e., T. cosimilis Ching et C. H. Wang, T. decurrenti-alata Ching et C. H. Wang, T. fengii Ching et C. H. Wang, T. simaoensis Ching et C. H. Wang are reduced to synonymies. As a re-suit, 22 species and two varieties are recognized in the genus Tectaria from Yunnan.     

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.     

云南叉蕨属(Tectaria Cav.)的增补与订正

叉蕨属是蕨类植物的大属之一,全世界约150种,分布于世界热带及亚热带地区。据记载,中国 有27种、2变种,分布在长江以南,仅有2种北达长江以北四川境内,而大部分种类集中分布在云南。近 来,笔者主要对保存在中国科学院昆明植物研究所标本室的标本进行了清理,也参考了中国科学院植物 研究所标本馆的标本,这些标本不少是近年来所采集,其中,发现1新种并有1种和1变种为中国新记 录,1种为云南新记录,1种为贵州新记录,有4个种名是新异名,即Tectaria cosimilis Ching et C．H．Wang, T．decurrenti-calata Ching et C．H．Wang,T．fengii Ching et C. H．Wang,T．Simaoensis Ching et C.H．Wang。至此,所知云南产叉蕨属有22种、2变种。     

A Monographic Revision of the Fern Genus Neolepisorus Ching

The genus Neolepisorus Ching was proposed in 1940 and then consisted of five species including the type, Polypodium ovatum Wall. ex Hook. et Grev. The generic sense of Neolepisorus is now more homogenour than originally constructed. Strictly speaking, the genus then had only three species: Polypodium ovatum Wall. ex Hook. et Grev. of the Himalayas and China, P. ensatum Thunb. of Japan, and China, and P. lastii Baker of Africa (Madagascar). Since then our knowledge of the genus has substantially been enriched, as there are now 10 species known from China as described in the present paper. Phylogenetically, the genus Neolepisorus is a natural one in the family Polypodiaceae, beiny closely related to Nicrosorium Link, Calysis Presl and Tricholepidium Ching in general habit, scale structure, spores and chromosome numbers (x = 36), while its affinity with the genus Lepisorus (J. Sm.) Ching is much less close in these respects. From its related genera Neolepisorus differs in terestrial habit,typically long-stipitate simple fronds, distinct lateral main veins with 1--3(4) striate and irregularly dispersed sori covered when young with angular, clathrate and long-stalked paraphyses. One marked morphological peculiarity of the genus Neolepisorus is, however, that the fronds in many species from Guizhou and Sichuan are so divided into more or less similarly pinnatifid or lobed monstrous shapes that their proper identity is frequently indiscernible--a character not yet seen in ferns of other genera in China at least. It offers an interesting research subject for the morphologists. Geographically, the genus Neolepisorus is mainly Chinese. Except one species endemic to Afrira (Madagascar), one in Indo Himalayas, upper Burma, nothern Thailand, Indo-China and China and the third species in Japan and China, all are found endemic to China,northwards to the southern part of Shaanxi (Shensi) Province, south of the Tsing-ling Range. Ecologically, they all prefer half-sunny floor under secondary forests or among shrubberies.     

云南产凤尾蕨属植物(凤尾蕨科)的新修订

在《中国植物志》和《云南植物志》的基础上,对云南产凤尾蕨属植物进行新的分类修订。文中澄清了8个混淆类群,其中新等级1种,即高原凤尾蕨Pteriscuspigera(Chingex Ching et S.H.Wu)X.Q.Song;云南分布新记录1种,即假指状凤尾蕨Pteris psudodactylina Ching et S.K.Wu;新异名3个,即Pteris asperi-caulis var.cuspigera Chingex Ching et S.H.Wu,Pteris inaequalis Bak.及Pteris wallichiana var.yunnanensis(Christ)Ching et S.H.Wu。还列出了新修订种类的文献引证、标本引证、生境和地理分布。经该文研究确认,现知云南有该属植物48种。
