【摘要】 在光镜下观察了泽米铁科分属于 3个属的 3种植物叶表皮特征 ,结果表明 :3种植物叶表皮细胞及气孔器差异显著 ,一定程度上证实了 3属是自然的分类群。在鳞秕泽米铁(Zamiafurfuracea)中发现了气孔簇。本文还对 3种植物之间的系统演化关系及它们对环境的适应性进行了讨论更多还原

【Abstract】 The leaf epidermal characters of three species ( Dioon holmgreii;Macrozamia moorei;Zamia furfuracea ) in Zamiaceae were oberserved under LM.The results showed that they are quite different each other.To some extent, they proved that the division of three genera was natural.Stomatal cluster was discovered in Zamia furfuracea .In addition,the relationship of systemtic evolution among three genera and their adaptability to enviroment were discussed.更多还原
