摘　　要：目的:对龙胆科三种地格达类蒙药材扁蕾、椭圆叶花锚、肋柱花的粉末及茎的横切片进行显微鉴别研究,为地格达类蒙药材的鉴定和开发利用提供参考。方法:用光学显微镜观察。结果:在三种蒙药材粉末中观察到了相同的气孔轴式、螺纹导管和纤维,及各不相同的花粉粒、叶表皮细胞和腺毛。在三者的茎横切片均可见表皮、皮层、韧皮部、木质部和髓,但构造形态有较大差异。结论:以上显微特征对龙胆科地格达类蒙药的鉴别具有一定意义。Objective：Study the microscopical characters of Gentianopsis barbata,Halenia elliptica and Lomatogonium carinthiacum which are the resource of ＂Digeda＂,to provide the reference for the identification and utilization of this Mongolian medicine.Methods：Microscopic identification.Results：In the three kinds of Mongolian medicinal powder,stomata type,spiral vessel and fiber have the same characteristic;pollen grain,epidermal cells,trichome have the different characteristic.All the three kind of the stem have epidermis,cortex,phloem,xylem and pith,but their structure and characteristic is different.Conclusion：The microscopic characteristics of the three Digeda species is tipycal.
