对中国薯蓣属(Dioscorea L.)40个种类地下茎的淀粉粒形态进行了显微观察.结果表明,中国薯蓣属植物地下茎淀粉粒主要有单粒和复粒2种形态.单粒淀粉粒以类圆形为主,脐点多为点状.复粒淀粉粒可分为2类:A型由2～3个淀粉小粒构成,以卵圆形和三角形为主,脐点点状且大多不明显,少数种类层纹清晰;B型由10个以上的淀粉小粒构成,以圆形为主,脐点不明显,无层纹.根状茎组(Sect. Stenophora Uline)、基生翅组(Sect. Opsophyton Uline)和周生翅组(Sect. Enantiophyllum Uline)均为单粒淀粉粒;顶生翅组(Sect. Shannicorea Prain et Burkill)为复粒淀粉粒A型;丁字型毛组(Sect. Combilium Prain et Burkill)和白薯莨组(Sect. Lasiophyton Uline)为复粒淀粉粒B型;复叶组[Sect. Botryosicyos (Hochst.) Uline]兼有单粒和复粒淀粉粒.淀粉粒形态特征支持白薯莨(D. hispida Dennst.)由复叶组分出单列成组及毛芋头薯蓣(D. kamoonensis Kunth)和高山薯蓣(D. delavayi Franch.)互为独立种的分类学处理.
