摘要: 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。

Abstract: The fern genus Coniogramme Fée is one of the ferns which are difficult in classification as there are many transitional types. C.robusta(H.Christ) H.Christ is a special kind among them. In this paper, the taxonomy of this species is revised based on examination of its herbaria specimens, fieldwork, and observation of spore morphology. C.pseudorobusta Ching et Shing and C.neorobusta Ching et Shing are reduced to C.robusta(H.Christ) H.Christ. Meanwhile, the type specimens of C.robusta var. splendens Ching et Shing and C.robusta var. rependula Ching et Shing are redefined.

Key words: Coniogramme Fé, e, C.robusta var. robusta, C.robusta var. splendens Ching et Shing, C.robusta var. rependula Ching et Shing, taxonomic revision
