摘要
本文根据中国石松目植物的形态演化及各科属间的进化关系,提出了中国石松目植物的分类系统。结果在石杉科的石杉属中建立了锯齿组和无齿组,马尾杉属中建立了腋生组、马尾组和绳索组;在石松科的石松属中建立了杉蔓石松组、石松组和玉柏石松组;并考证了各科属的文献来源及学名的沿革,阐明了国产石松目植物的种数、分布及资源情况,为进一步开发利用本目植物提供了分类学基础。
The Lycopodiales comprise about 220 species,of which 63 species and 10 varieties oc- cur in China.In this paper a classification system of Lycopodiales based on its morphology and characteristics in evolution is described. The genus Huperzia could be divided into 2 sections,ie the section Serratae (13 spe- cies,2 varieties) and the section Huperziae (15 species,1 variety),the genus Phlegmariurus, 3 sections:the Hamiltonianae (11 species),the Phlegmaria (3 species,1 variety) and the Fu- niformes (5 species) and the genus Lycopodium,also 3 sections:the Annotinae (3 species,2 varieties),the Clavatae (3 species,2 varieties) and the Obscurae (1 species,1 variety). The family Lycopodiaceae consisting of Lycopodium,Palhinhaea,Diphasiastrum,Lyco- podiella and Lycopodiastrum is more advanced than the family Huperziaceae (consisting of the genera Huperzia and Phlegmariurus) in phylogeny.
