摘　　要：应用植物形态分类和区系地理的方法,研究了蒙古高原八宝属植物的种类及其区系生态地理的分布特征和规律。修改了《内蒙古植物志》(第二版)中一些种图版的错误说明和产地的不确切分布,认为所记载的库布齐八宝应为华北八宝[Hylotelephium tatarinowii(Maxim.)H.Ohba],且在鄂尔多斯没有分布。确认蒙古高原现共有5种八宝属植物,编制分种检索表,并分别绘制了分布区图。The classification, geographical distribution features and rules of the Hylotelephium plants in Mongolia Plateau were identified by the methods of shape taxonomy and modern botany ecological geography. The results showed that.（1） actually Hylotelephium almae （Froederstroem） K. T. Fu ＆ G. Y. Rao recorded in Flora of Inner Mongolia （ed. 2） ,is H. tatarinowii （Maxim.） H. Ohba and it dose not distribute in Ordos; （2） There were totally five species of Hylotelephium in Inner Mongolia Plateau, and a new claves Plantarum of Hylotelephium was given and their distribution areas were mapped according to the sites of collected specimens and records derived from a variety of flora; （3） The indefinite distributional areas and the wrong accounted pictures of some Hylotelephium species in Flora of Inner Mongolia （ed. 2） were corrected.
