摘　　要：本文用扫描电子显微镜较详细地观察了中国产卷柏科Selagincl aceae植物的28种小孢子和26种大孢子的形态特征。该科孢子纹饰复杂而较稳定,较大的纹饰往往由较小的规则的纹饰构成;个别种的大孢子有单裂缝类型;同种内大小孢子纹饰不相似;作者据孢子形态学特征支持将卷柏科分为两类(相当于两个属或一个属的两个亚属),即同型叶类和异型叶类,并将异型叶类分为五个种组;根据孢子纹饰等讨论了科属内的演化关系。The morphological characteristics of the microspores of 28 species andthe megaspores of 26 species in the family Selaginellaceae from China wereobserved in detail by using scanning electron microscope. The ornamenta-tions cf both spores of different species in the Selaginellaceae are diver-sified and stable. The larger ornamentations are always composed of theregular smaller ones. The o? namentations of both spores in the same spe-cies are not similar. Acconding to the morphological characteristics of thespores the authors support the view that the Selaginellaceae divide into 2groups (2 genera or one genus divide into 2 sub genera) i. e. Homeophyllumand Heterophyllum, and suggest that Heterophyllum may be subdivided into5 group. On the basis of the ornamentations of spores the relationship inthe family are discuused.
