摘要:

本文研究了华南地区羽枝藓属（Ｐｉｎｎａｔｅｌｌａ）和凋叶藓属（Ｃａｄｕｃｉｅｌｌａ）植物．简要讨论了羽枝藓属和凋叶藓属的系统位置．确认华南地区产羽枝藓属４种，即爪哇羽枝藓（Ｐ．ａｎｂｉｇｕａ）、纤细羽枝藓（Ｐ．ａｎａｃａｍｐｔｏｌｅｐｉｓ）、嵌边羽枝藓（Ｐ．ｉｎｔｒａｌｉｍｂａｔａ）和东亚羽枝藓（Ｐ．ｍａｋｉｎｏｉ），凋叶藓２种，即广东凋叶藓（Ｃ．ｇｕａｎｇｄｏｎｇｅｎｓｉｓ）和凋叶藓（Ｃ．ｍａｒｉｅｉ）．其中爪哇羽枝藓为广东、贵州、海南岛之新记录，纤细羽枝藓为中国大陆（广东、广西）和海南岛之新记录，东亚羽枝藓为福建、广西和海南岛之新记录，广东调叶藓为海南岛之新记录，暂将Ｐ．ａｌｏｐｅｃｕｒｉｏｉｄｅｓ处理为存疑种。本文还包括分种检索表、各种的简要识别特征、产地及生境资料．

Abstract:

A taxonomic reunion reveals that four spevies of the genus, P. ambigua, P. anacamptolepis, P. intralimbataand P. makincli two species of Caduciella, C. guangdongensis and C. mariei occur in South China. P. ambigua in Guangdong, Guizhou and Hainan Island, P. anacamplolepis in mainland China (Guangdong, Guagnxi) and Hainan Island,P. nakinci in Fujian, Guangxi and Hainan Island, C. guangdongensis in Hainan Island are reported for the first time.P. alopecuroides is treated as a doubtful species. Diagnostic charaders, distributions, laslitiot, habitsts and a key to the studied species are provided.
