摘 要 ：对国产耳橛属(Polystichum)后生耳橛组(Sect．Metapolystichum)26种的孢子形态进行了研究。结果表明，后生耳蕨组的孢子周壁纹饰可大致分为粗糙、翅状、脊状、疣状、穴状和网状6类。各种的周壁纹饰均有一定差异，同种的孢子形态较为稳定。从孢子形态特征看，支持Polystichum yunnanense Christ和 P.jizhushanense Ching为独立的种。本文还结合其它特征，讨论了后生耳蕨组孢子形态的演化趋势，进而从孢粉学的角度推测本组线鳞系Ser．Linearia可能是较为原始的一群，失盖Ser．Exindusiata则可能为较为进化的一支。本文还以孢子形态特征编制了后生耳蕨组分种归类检索表。

Abstract:The spores of 26 species of Scet. Metapolystichum(Polystichum) in China have been studied under LM and SEM. The results show that the spores are monolate, elliptic in polar view, reniform in equatorial view, all with perines, (24.3-45.6) x (28.2-61.4) x (24.3-57.1)/xm in size. The perine sculptures of 26 species almost are different from one another and can be divided into 6 types: scabrate, wing-like, cristate, verrucate, foveolate and reticulate.
