| 摘要: |
| 利用光镜和扫描电镜,对石韦属(Pyrrosia)19种植物的孢子纹饰进行了研究。结果表明:19种石韦属孢子都为黄色,形态均为肾形,两侧对称,单裂缝,说明该属植物是一个自然类群。表面纹饰类型有3种,即瘤状、瘤状—疣状和瘤状—网脊状。孢子表面纹饰特征性状稳定,在种间存在较大差异。该研究结果可以为形态近似种的分类提供参考依据,同时也为石韦属属下分类系统的建立提供了重要证据。 |

| Abstract: |
| The spores of nineteen taxa of genus Pyrrosia were examined by means of light microscopy(LM)and SEM. It was showed the color of the spores was yellow. There were three main ornamentation types, tuberculate, verrucate-tuberculate and tuberculate-murus. The evidence from spore ornamentations was stable, and can be used to differentiate the affined species in this genus. |
