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。     

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。     

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。     

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。     

中国肿足蕨科一新记录属——翼囊蕨属（英文）

报道了中国肿足蕨科一新记录属——翼囊蕨属(Didymochlaena Desv.)。该属为泛热带分布的单型属,在中国为首次记录。本文结合原始文献对该属及其折囊蕨种的特征进行了详细描述。

中国鳞毛蕨属泡鳞亚属的分类研究

鳞毛蕨属ＤｒｙｏｐｔｅｒｉｓＡｄａｎｓ．泡鳞亚属ＳｕｂｇｅｎｕｓＥｒｙｔｈｒｏｖａｒｉａｅ（Ｈ．Ｉｔｏ）Ｆｒａｓｅｒ－ＪｅｎｋｉｎｓｉｎＢｕｌ．Ｂｒ．Ｍｕｓ．Ｎａｔ．Ｈｉｓｔ．Ｂｏｔ．１４（３）：１９５．１９８６．Ｔｙｐｅ：Ｄｒｙｏｐｔｅｒｉｓｅｒｙ...     

国产毛蕨属（金星蕨科）六新异名

将乐清毛蕨（ Cyclosorus luoqingensis ）处理为德化毛蕨（C．dehuaensis）的异名,南岭毛蕨（C．narlingensis）和少羽毛蕨（C．paucipinnus）处理为[梣]叶毛蕨（C．fraxinifolius）的异名,倒披针毛蕨（C．oblanceolatus）处理为南平毛蕨（C．nanpingensis）的异名,雁荡毛蕨（C．yandongensis）和寻乌毛蕨（C．xunwuensis）处理为华南毛蕨（C．parasiticus）的异名,并作了相应的讨论。     

A new combination in Leptolepidium (Pteridophyta: Sinopteridaceae)

The genus Leptolepidium (Sinopteridaceae) is maintained and the species Cheilanthes duthiei from the Himalayas is transferred to it.     

A new species of Polystichum (Pteridophyta: Dryopteridaceae) from South Africa

A new Polystichum (Pteridophyta: Dryopteridaceae) species, P. incongruum J.P.Roux sp. nov. from the Western and Eastern Cape Provinces from Soudi Africa is described. This variable species is related to P. pungens (Kaulf.) C.Presl but differs from it in pinnule morphology, the frequent occurrence of glandular cells along the sporangium stalk, the (more rare) occurrence of clavate unicellular glands along the indusium margin and a chromosome number of 2 n = 164.     

A new combination in Maranthes (Chrysobalanaceae)

Maranthes, previously known in the Neotropics only from Panama, has recently been collected in Nicaragua and Costa Rica. Prior to publication of the Chrysobalanaceae of theFlora de Nicaragua, the new combinationMaranthes panamensis (Standl.) Prance & F. White is made and based onCouepia panamensis, previously considered conspecific with the AsiaticM. corymbosa Blume.     

Six new species and two new records of (Pteridophyta) from Costa Rica

Six new species of Pteridophyta from Costa Rica are described: Dryopteris flaccisquama A. Rojas, Hypolepis lellingeri A. Rojas, H. moraniana A. Rojas, Melpomene alan-smithii A. Rojas, Selaginella osa?nsis A. Rojas and Terpsichore esquiveliana A. Rojas. Blechnum stoloniferum (Mett. ex E. Fourn.) C. Chr. and Trichomanes micayense Hieron. are new records for the country. Only D. flaccisquama and M. alan-smithii are present outside Costa Rica.     

Nineteen new species of Elaphoglossum (Elaphoglossaceae, Pteridophyta) from Bolivia

We describe and illustrate 19 new species ofElaphoglossum from Bolivia:E. ayopayaense, E. carrascoense, E. choquetangae, E. cotapatense, E. crispipalea, E. cruzense, E. elkeae, E. ellenbergianum, E. gonzalesiae, E. inquisitivum, E. madidiense, E. murinum, E. neei, E. palmarum, E. pannosum, E. paucinervium, E. puberulentum, E. pulchrum, andE. sunduei.     

A new nomenclatural combination inPortulacaceae (Centrospermae)

Examination of type specimens of the monotypic genera,Grahamia (G. bracteata) andTalinaria (T. palmeri) together with detailed palynological, morphological and seed anatomical evidence have shown that these two species are very similar. These two genera are subsequently grouped into one genus,Grahamia. A new combination,G. palmeri is now proposed.     

杆孢赤壳属一新组合(英文)

长期以来,杆孢赤壳属被视为丛赤壳属的异名,最近才恢复其属级分类地位。臧氏丛赤壳在形态特征上与杆孢赤壳属的模式种Allantonectria miltina很相似,在子囊壳解剖结构、近圆柱形至柱棒状子囊、腊肠形子囊孢子等方面均表现出共性。二者间形态相似性得到了6个基因序列分析的支持,因而将臧氏丛赤壳转入杆孢赤壳属,建立新组合臧氏杆孢赤壳。
