摘要:

青藓科是侧蒴藓类植物中种类最为丰富、分类学问题较多的类群之一。以青藓科19属、44种,594份标本为研究对象,对其假鳞毛特征进行了系统研究。结果表明:①青藓科假鳞毛均为三角形至半圆形的叶状假鳞毛;根据其顶端特征又可划分为两种类型:顶端平截或钝,顶端具毛尖;②除青藓属(Brachythecium)外,其余18属内不同种间的假鳞毛形态基本一致;③假鳞毛形态特征在青藓科植物属级水平分类上具有一定的分类学价值。

Abstract:

Brachytheciaceae is one of the most diverse and problematic taxonomic families in pleurocarpous mosses. In this paper, the morphology of pseudoparaphyllia of 594 specimens in Brachytheciaceae, which belonged to 19 genera and 44 species, were studied. Results were as follows: ①In Brachytheciaceae, pseudoparaphyllia was triangular to semicircular foliose. According to its apical characteristics, pseudoparaphyllia could be divided into two types: truncate or obtuse, and acuminate. ②Except for the genus Brachythecium, morphology of pseudoparaphyllia among the different species in the other 18 genera was basically the same. ③Morphology of pseudoparaphyllia had taxonomic significance in the genus level.

Key words: pleurocarpous mosses, Brachytheciaceae, morphology, taxonomy
