摘要：

本文概述了岩蕨类植物研究简史，承认岩蕨科是独立的科，在细胞学和比较形态解剖学

研究基础上，提出岩蕨科系统演化模型，讨论了科内系统发育和种间亲缘。岩蕨属Woodsia的

甘南岩蕨W．macrospora是本科最原始的种。岩蕨科可能起源于里白科植物祖先，演化成

现代岩蕨属和膀胱蕨属Protowoodsia两大分支。本文还探讨了多倍化和种系发生的关系，滇

蕨Cheilanthopsis indusiosa (Christ) Ching、高山岩蕨W．alpina Gray、心岩蕨W．subcordata

Turcz．和蜘蛛岩蕨W．andersonii (Bedd．) Christ可能是异源多倍体。

Abstract:

The history of the study on the woodsiodes is briefly surveyed in the paper.

The family Woodsiaceae is recognized by the present author. The relationships among the spe-

cies and the probable evolution of the family are discussed based on author's cytological and

comparative morphological studies, and are indicated by Wagner's method, with numerical

values as the indices. Woodsiaceae may have originated from the common ancestor of modern

Dicranopteris and Sticherus of Gleicheniaceae, and evolved from it into two main branches, i.e.,

Woodsia and Protowoodsia. The origin of species through polyploid series are discussed, and

W. andersonii, W. subcordata, W. alpina and Cheilanthopsis indosiosa considered as fertile al-

lopolyploids; the probable way of speciation is also suggested for these species.

Key words: Woodsiaceae, phylogeny, polyploid
