摘　　要：利用光学显微镜和扫描电子显微镜详细观察了松叶蕨科 (Psilotaceae) 2属 3种植物的孢子形态 ,即松叶蕨属(PsilotumSw .)中的 2个种 :P .nudum(L .)Beauv .和P .complanatumSw .,梅西蕨属 (TmesipterisBernh .)中的 1个种 :T .elongataDang .。The spores of three species of Psilotaceae were observed under LM and SEM. The morphological characters of them were described in detail.The spore morphology of Psilotum Sw. and Tmesipteris Bernh. is different from each other and there are differences in spore morphology between the two species of Psilotum Sw.
