报道了浙江省乌岩岭国家级自然保护区12种凤尾藓属(Fissidens)植物,其中内卷凤尾藓济州岛变种(F.involutus Wilson ex Mitt.var.jejuensis Y.-J.Yoon,B.C.Tan&B.-Y.Sun)为中国首次报道,该变种此前只分布在日本和韩国,其特征是背翅基部明显下延,鞘部细胞的每个角都有1个不明显的疣.异形凤尾藓(F.anomalus)和锐齿凤尾藓(F.serratus)为浙江省新记录.在该保护区,凤尾藓属植物物种多样性随海拔升高呈单峰分布.与我国东南部地区其它保护区相比,乌岩岭的凤尾藓多样性仅次于广西的雅长自然保护区.而且,这一地区凤尾藓的多样性并没有表现出随着纬度的降低而增加的趋势.因此,建议进一步加强对我国东南部地区凤尾藓的调查和研究.
Diversity of Fissidens in Wuyanling National Nature Reserve, Zhejiang Province, China
Twelve species of Fissidens are reported for Wuyanling National Nature Reserve, Zhejiang Province, China. Fissidens involutus Wilson ex Mitt. var. jejuensis Y.-J. Yoon, B.C. Tan & B.-Y. Sun, a new variety previously known only from Japan and South Korea, is reported here for the first time from China. This species is characterized by the bases of dorsal leaves are distinctly decurrent, and cells of vaginant lamina have single indistinctly papilla at each corner. Detailed description and illustrations of F. involutus var. jejuensis are provided. In addition, two species, viz. F. anomalus and F. serratus are new provincial records for Zhejiang Province. In Wuyanling, a humped distribution is observed of the Fissidens species diversity with the elevation. Compared with other nature reserves in southeastern region of China, the number of species of Fissidens in Wuyanling is the second only to Yachang Nature Reserve (Guangxi). Furthermore, species diversity of Fissidens does not increase as the latitude decreases in this region. Hence, it is recommended to carry out further investigation and study on the diversity of Fissidens in southeastern region of China.
