摘　　要：本文试图澄清内蒙古究竟有多少种景天属植物,这些植物在内蒙古的生态分布情况。我们应用形态—地理分类的方法,对内蒙古景天属Sedum植物进行认真研究。研究认为:《内蒙古植物志》第二版记载的北景天(Sedum kamtschaticum Fisch.)和兴安景天(Sedum hsinganicumChu.)应为费菜;确定了兴安景天(Sedum hsinganicum Chu.)和费菜(Phdeimusaizoon L.)为温带亚洲分布种;阔叶景天(Sedum roborowskii Maxim.)为青藏高原东部分布种;藓状景天(Sedum polytrichoides Hemsl.)为中国-日本分布种;内蒙古景天属植物从东部渗入了1种东亚成分,从西南部渗入了1种青藏高原成分。The purpose of this study is to make clear how manySedum plants are there in Inner Mongolia？ Where are the ecological distribution of these plants in Inner Mongolia？ The results show thatSedum hsinganicum Chu. and Sedum kamtschaticum Fisch. in （F1. Inner Mongolia） （ ed. Second Version Vol. 3. 1989 ） should bePhdeimus aizoon L. ;It is confirmed thatSedum hsinganicum Chu. andPhdeimus aizoon L. distribute in Aisa temperate zone Sedum roborowskii Maxim. is distributive specie of east of Qing Zang plateau ;Sedum polytrichoides Hemsl. is distributive specie of China - Japan .,Sedum in Inner Mongolia permeated two members of eastern Asian from east part and one member of Oing Zang plateau from southwest part.
