摘要:

利用光学显微镜和扫描电子显微镜对云南产水龙骨科水龙骨亚科4 属8 种1 变种植物的孢子进行了
详细观察, 其中篦齿蕨Metap olypodium manmeiense 以及扫描电镜下观察的蒙自拟水龙骨Polypodiastrum
mengtzeense 为首次报道。研究结果表明, 该亚科植物孢子形态较为一致, 均为单裂缝, 两侧对称, 极面观
为椭圆形, 赤道面观为豆形, 具周壁或不具周壁, 外壁正面观均为较整齐的疣状纹饰。本文还就孢子形态
及其与该亚科植物的系统分类和演化关系进行了讨论, 为水龙骨科的系统分类及孢粉学研究提供了资料。

Abstract:

The spores of 8 species and 1 variety belonging to 4 genera of Polypodiaceae subfam. Polypodioideae in Yunnan,
China were examined under LM and SEM. Of the species it is the first time to study the spores of Metapolyp odium
manmeiense and Polypodiastrum mengtzeense under SEM. The results show that the spores of this subfam. Polypodioideae
are morphologic uniform; they are monolete, bilaterally symmetric, ellipsoidal in polar view, bean- shaped in equatorial
view, and with or without perispore. The surface ornamentation is regularly verrucate. In addition, the relationship of the
spore morphology and taxonomy in Polypodiaceae subfam. Polypodioideae was discussed in this paper, providing more informative
data for the systematics and palynology of Polypodiaceae.

Key words: Spore morphology, Polypodiaceae subfam. Polypodioideae, Yunnan
