摘 要 ：本文采用光镜(LM)、扫描电镜(SEM)相结合的方法，对产于我国的13种苏铁的表皮特征进行了比较研究。篦齿苏铁、攀枝花苏铁、台东苏铁及苏铁的气孔为一种类型，明显不同于另外9种苏铁的气孔。结果支持C. taitungensis（台东苏铁）成立。根据叶表皮特征，作者还对这边13种苏铁的系统位置进行了初步探讨。

Abstract:The leaflet epidermal characters of thirteen species of Cycas in China were comparatively analysised. Based on the resemblance of stomata and cuticle characters, C. pectinata, C. panzhihuaensis, C. taitungensis, C. revoluta were assigned in one group, which possess stomata Type II (with elongated stomatal margin cells, more than 10 accessory cells), and other nine species in another group, which possess stomata Type I (with normal stomatal margin cells, about 7 accessory cells). Our result also told the difference of stomata between C. taitungensis and C. taiwaniana.
