中国帕米尔高原黄耆属的分类学研究

通过野外考察、查阅文献和标本鉴定,对中国帕米尔高原黄耆属(Astragalus L.)植物进行形态分类学研究。结果表明:中国帕米尔高原有黄耆属植物23种,其中神圣黄耆(Astragalus dignus)是中国新记录种,高山黄耆(A.alpinus)是中国帕米尔高原新记录种。对物种学名的考证发现,以前国内文献记载的产于本区的A.mendax,A.alatavicus,A.laspurensis分别是A.charguschanus,A.pamirensis,A.petraeus,同时也采集到了A.laspurensis的标本,证实本种在该区确有分布。同时还给出了23种黄耆属植物的分种检索表,并对其生境和分布作了介绍。
