| 摘 要： | 对紫玉盘属８种，杯冠木属３种和Ｅｌｌｉｐｅｉａ属 １种进行了叶的比较研究，以调查不同种之间解剖 学的不同点，这对种的鉴别和了解它们的分类学意义可能是有用的。有意义的解剖学特征是：末端石细 胞，表皮细胞的晶簇，毛状体，在中脉和叶柄的薄壁组织内的短石细胞以及中脉和叶柄横切面的形状。 有某些特征仅出现在某些种中，这对种的鉴别是有用的。结果亦显示这三个属的联系十分紧密。

| Abstract: | A comparative study was undertaken on the leaves of eight Uvaria, three Cyathostemma and one Ellipeia species in order to investigate interspecific anatomical differences which could be useful in species identification and their taxonomic significance. Anatomical characters that are of significance are terminal sclereids, druses in epidermal cells, trichomes, brachysclereids in parenchymatous tissues of midribs and petioles, and the shape of midribs and petioles in transverse sections. Certain features are present in certain species only and are thus useful for species identification. The results also show that the three genera are quite closely related. |
