摘要:

马尾杉属植物因含治疗阿尔茨海默症的特效药成分石杉碱甲而具有重要的经济价值和保护价值,全属为国家重点保护植物。该文基于形态学、生态学和地理学等证据,对中国分布的马尾杉属植物进行了分类修订,承认我国有马尾杉属植物21种,将该属植物划分为4个单系的组,即金丝条马尾杉组(Sect. Fargesiani X. C. Zhang & R. H. Jiang,sect. nov.)、喜马拉雅马尾杉组(Sect. Hamiltoniani C. Y. Yang, emend. X. C. Zhang & R. H. Jiang)、马尾杉组(Sect. Phlegmariurus)和粗糙马尾杉组[Sect. Squarrosurus(Herter)X. C. Zhang & R. H. Jiang,comb. & stat. nov.],并将Huperzia medogensis、Phlegmariurus austrosinicus、P. changii、P. nylamensis、P. cancellatus var. minor、P. qiongzhongensis和P. shangsiensis的名称作为异名处理。

Abstract:

Plants of the lycophyte genus Phlegmariurus contain the chemical compound Huperzine A, the effective medicinal component treating Alzheimer's disease, thus with huge economic value. To protect the natural resources, plants of the whole genus are listed as the National Key Protected Wild plants in China. In this paper, we revised the taxonomy of Phlegmariurus distributed in China based on morphological, ecological, and geographical evidence. We recognized 21 species from China, and organized them into four sections. Sect. Fargesiani X. C. Zhang & R. H. Jiang is newly established, and the other three sections were revised based on previous studies, i.e., Sect. Hamiltoniani C. Y. Yang, emend. X. C. Zhang & R. H. Jiang; Sect. Phlegmariurus; and Sect. Squarrosurus(Herter)X. C. Zhang & R. H. Jiang, comb. & stat. nov. We reduced the following taxon names to synonymies of various species of Phlegmariurus: Huperzia medogensis, Phlegmariurus austrosinicus, P. changii, P. nylamensis, P. cancellatus var. minor, P. qiongzhongensis, and P. shangsiensis.
