河北省绢藓属(Entodon)植物的分类与地理分布

A preliminary study on the taxonomy and distribution of Entodon in Hebei Province,China

在研究文献和标本的基础上 ,简要回顾了绢藓属 (EntodonC .Muell.)植物在中国以及在河北省的研究背景。对采自河北省的 2 1 0余号绢藓属植物标本进行了研究鉴定 ,整理出河北省绢藓属植物 1 4种 2变种 ,其中有河北省新记录 2种 :细疣绢藓 (Entodonverruculosus)和中华绢藓 (E .smaragdinus)。按照吴征镒先生对中国种子植物属的分布类型划分原则[1 ] ,河北省绢藓属植物可划分为 4个类型 ,其中 ,密叶绢藓短柄变种 (E .compressusvar.zikaiwiensis)、亮叶绢藓 (E .aerugi nosus)、陕西绢藓 (E .schensianus)、中华绢藓、短柄绢藓 (E .micropodus)、和细疣绢藓 6种为中国特有分布。作者根据标本编制了河北省绢藓属植物分种检索表 ,并概述了每一种的生境、识别特征和地理分布。最后 。

In views of the advance of research on the genus Entodon and according to the specimens about 210 packets collected from Hebei Province, 16 species (including 2 varities) are recognized currently. Among them, two species (Entodon verruculosus, E. smaragdinus) are newly mosses recorded to Hebei Province. All the 16 species can be classified into 4 elements based on Z Y Wus \ thesis differentiating the areal-types of Chinese genera of seed plants. Among them, E. compressus C. Muell. var. zikaiwiensis, E. aeruginosus, E. schensianus, E. smaragdinus, E. micropodus and E. verruculosus are endemic to China. The general data on habits, diagnostic, geographic distributions and illustrations about these taxon are discussed. A key to the species of Hebei Province is provided.
