摘　　要：目的:观察长柄山姜(傣草蔻)、宽唇山姜、云南草蔻3种姜科山姜属植物根茎的显微特征,制定显微鉴别指标。方法:采用石蜡切片、徒手切片和粉末显微特征进行鉴定。结果:3种山姜属植物根茎的显微比较可从表皮有无非腺毛及细胞结构、内皮层是否明显及细胞结构、维管束纤维是否木化、维管束数量及存在方式、导管数量及大小等方面差异来区别。粉末鉴定主要依据非腺毛的有无、螺纹导管的有无、淀粉粒形状等特征加以区别。结论:根茎的显微特征可为3种山姜属植物的鉴定提供参考依据。Objective：To observe microscopic characteristics of rhizome of Alpinia kwangsiensis ,Alpinia platychilus ,Alpinia blepha- rocalyx ,and to provide basis for their identification. Methods：Microscopic identification of root transverse section by paraffin tissue section and free-hand section and powder were carried out to distinguish them. Results：The microscopic identification can be made by cell structure of epidermis and endodcrmis, the existence of nonglandular hair, the lignification degree of vascular bundle fiber, the number and existence style of vascular bundle fiber, the number and size of tube, and so on. The powder identification can be made mainly according to the existence of nonglandular hair and spiral vessel, the shape of starch grain, and so on. Conclusion ： The microscopic characteristics of rhizome can provide basis for the identification of three Alpinia species.
