摘要
对绞股蓝属（Ｇｙｎｏｓｔｅｍｍａ）植物的１３种和１变种的种子进行了扫描电镜观察，结果表明本属植物种子表皮特征有光滑型和具纹饰型两大类。且以具纹饰型种类为主。就种的特征而言，每种在种子表皮细胞的形态、大小、纹饰等特征又各自有别，是较好的分类性状。
The epidermal surfaces of seeds from 13 species and 1 variety of the genus Gynostemma were examined by Scanning Electricity Microscope (SEM). The results showed the microstructural features of seeds surfaces can be divided into smooth and ornamentation types. And most species are ornamentation type, these features and size of epidermal cell are quite distinct in different species. It has high taxonomic significance.
