摘要: 本文对5种中国产瘤蕨属植物的孢子形态的进行了光镜和扫描电镜的观察,其中2种的扫描电镜观察是首次报道,对形态特征和分类学意义进行了讨论,阔鳞瘤蕨与瘤蕨孢子表面纹饰的明显区别为新种阔鳞瘤蕨的成立提供了有力证据。

关键词: 瘤蕨属, 孢子形态, 扫描电镜, 分类学意义

Abstract: Spores of 5 species of Phymatosorus from China were examined under LM and SEM, 2 species are reported for the first time under SEM, the morphological characters of each species are described, with discussion of its implication on the systematics and paly nology in Microso rioideae(Polypodiaceae). The evidence from spore morphological characters supports Nooteboom's(1997) treatments of new species(P. hainanensis).

Key words: Phymatosorus Pic. Serm., spore morphology, SEM, taxonomic significant
