摘    要:利用光学显微镜和扫描电子显微镜对水龙骨属(PolypodiodesCh ing)植物11种(包括1变种)的孢子进行了观察和比较研究。其中,大部分种为首次报道。水龙骨属植物的孢子单裂缝,两侧对称,极面观椭圆形,赤道面观豆形或超半圆形,表面具疣状纹饰,多不具周壁。对光茎水龙骨(P.wattii)和日本水龙骨(P.niponica)、栗柄水龙骨(P.m icrorhizoma)与篦齿蕨(M etapolypodium manm eiense)亲缘关系进行了讨论,为该属植物的系统分类提供了孢粉学方面的证据。根据水龙骨属植物孢粉形态上的证据,水龙骨属植物是一个自然的分类群,赞成秦仁昌1978分类系统的分类处理。

关 键 词:水龙骨属  孢子形态  中国西南地区

Abstract:The spores of 11 species(including 1 variety) of Polypodiodes Ching were examined under LM and SEM,and most of the species were studied for the first time.The spores of Polypodiodes are monolete,bilaterally symmetric,elliptic in polar view and kidney shaped or semirounded in equator view.Based on the spore morphology,the relationships between P.wattii and P.niponica,P.microrhizoma and Metapoly-(podium) manmeiense were also discussed,providing the palynological to the systematics of Polypodiodes.According to the study at the palynology of this genus,we concluded that Polypodiodes is a natural taxon and agreed with Ching's point in 1978.
Keywords:Polypodiodes Ching  Spore morphology  SW China
