薄鳞蕨属的分类研究

在野外考察和室内标本研究的基础上,对薄鳞蕨属（中国蕨科）的分类进行了研究。 将2种 (华西薄鳞蕨和察隅薄鳞蕨) 和2变种（大叶薄鳞蕨和宽叶薄鳞蕨）进行了归并处理, 承认该属有4种1变种。     

薄唇蕨属的分类研究

薄唇蕨属是水龙骨科星蕨类植物中的一个小属,其范围时大时小,没有稳定的概念。我们在编 写《中国植物志》的过程中,分析了该属植物和星蕨类其它属植物的形态和地理分布,扫描了全部种类的孢子,认为薄唇蕨属不同于线蕨属,它包括了过去分出的似薄唇蕨属和树舌蕨等属。     

中国及邻近地区线蕨属的分类研究

在野外考察和植物标本研究的基础上,结合孢粉学、细胞学和植物地理学资料,对中国及邻近地区的线蕨属植物进行了修订,初步鉴定出9种和1杂种。在线蕨C．elliptica下划分出5个变种。首次发现褐叶线蕨Colysis wrightii的孢子囊中有鳞片状隔丝。     

薄鳞蕨属(中国蕨科)植物的孢子形态研究

对薄鳞蕨属5种3变种的孢子形态进行了光镜和扫描电镜观察。该属植物的孢子明显地分为两种类型：薄叶薄鳞蕨和杜氏薄鳞蕨的孢子为近球形,周壁为鸡冠状或拟网状纹饰;而华北薄鳞蕨、华西薄鳞蕨和绒毛薄鳞蕨的孢子为四面体状球形,周壁表面近光滑。第一种类型的孢子也存在于粉背蕨属,因此薄鳞蕨属和粉背蕨属的关系仍需进一步的研究。     

中国的骨碎补科

本文讨论了骨碎补科属的划分问题,承认了骨碎补属、钻毛蕨属、雨蕨属和大膜盖蕨属。小膜盖蕨属和阴石蕨属的种类被并入到了骨碎补属。中国计有骨碎补科植物3属14种,其中骨碎补属12种,雨蕨属1种,大膜盖蕨属1种。

薄鳞蕨属(中国蕨科)一新组合

承认中国蕨科薄鳞蕨属的独立性,把喜马拉雅地区分布的Cheilanthes duthiei 新组合到了该属。     

中国特有蕨属扇蕨属（水龙骨科）的系统学研究

扇蕨属（Neocheiropteris）为中国蕨类植物4个特有属之一。自Christ建属以来,不同的分类学者对本属的范畴以及系统位置一直存有争议。本研究对扇蕨属和盾蕨属进行了形态解剖观察,并对扇蕨属及其近缘类群共14个种的4个叶绿体DNA片段：rbcL、rpS4 ＆ rpS4-trnS IGS、trnL intron ＆ trnL-trnF IGS以及atpB ＆ atpB-rbcL IGS进行测序,应用最大简约法（Maximum-parsimony）、最大似然法（Maximum-likeli-hood）和贝叶斯推断（Bayesian inference）对序列进行联合矩阵分析,并构建系统树。该研究从形态学和分子系统学方面都提出了支持扇蕨属和盾蕨属分立的证据。形态学研究显示扇蕨属和盾蕨属叶片分裂方式、叶被和侧脉特征迥异,支持扇蕨属和盾蕨属的分立;但两属根状茎鳞片的共同特征则反映了两属问的紧密联系。分子系统学研究表明扇蕨属与毛鳞蕨属和鳞果星蕨属构成姐妹群,其集合与盾蕨属构成姐妹群。综合形态学和分子系统学的证据,对扇蕨属的系统位置以及范畴进行了深入探讨,扇蕨属包括扇蕨和三出扇蕨,结合形态学和分子系统学证据对三出扇蕨的系统位置进行了初步探讨。     

云南产轴鳞蕨属（三叉蕨科）植物的分类研究

采用R．E．Holttum与P．J．Edwards1986年提出的轴鳞蕨属Dryopsis的概念,对云南产的轴鳞蕨属植物进行分类研究。云南产轴鳞蕨属植物共有8个种,其中,独立江轴鳞蕨Dryopsis dulongensis(S.K.Wu et X.Cheng）S．Y．Dong为新组合,Dryopsis fengiana(Ching)Holttum et Edwards为新异名。并列出了分种检索表、种的文献引证、标本引证和地理分布。     

Taxonomic studies of the fern genus Lepidomicrosorum Ching et Shing (Polypodiaceae) from China and neighboring regions

The genus Lepidomicrosorum was separated from Microsorum Link by Ching and Shing in 1983. It is characterized by minute scattered sori covered with peltate and subsessile paraphyses when young. Tagawa detected that Polypodium subhastatum Baker, the type of this new genus, has this kind of paraphyses and thus transferred this species to Neocheiropteris Christ in 1952, a genus with divided lamina. During our study of the Microsoroideae, a revision of Lepidomicrosorum from China and neighboring regions is made on the basis of field and herbarium observation and evidence from anatomy, spore morphology, ecology, and distribution. Lepidomicrosorum is recognized as an independent genus and the demarcation line of its species is reconfirmed. Species with peltate scale-like paraphyses in Microsorum were transferred to Lepidomicrosorum. As a result, two species are recognized in this species, i.e.L．buergerianum (Miq.) Ching et Shing and L. hymenodes (Kunze)L. Shi et X. C. Zhang.

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.     

宽带蕨属（水龙骨科）的系统学研究

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, 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.
