通过对黄芪组的分类和系统发育研究，我们从伊朗西北部鉴定出一新种，命名为A.emotispicatus spc.11月，在此进行了描述和说明。它在形态上类似于A.Karlheinzii，具有疏松的花序。核糖体DNA内转录间隔区(ITS)区域的系统发育推断支持A.Remotispicatus作为这一组疏松花序群中一个明显不同的物种。此外，还对松材线虫的位置进行了研究。亚会话属被发现是错误的，并且这个分类单元应该被视为在A.kohrudicus内的一个异名。
As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov., which is described and illustrated here. It is morphologically similar to A. karlheinzii in possessing a lax inflorescence. Phylogenetic inference of the nuclear ribosomal DNA internal transcribed spacer (ITS) region support A. remotispicatus as a clearly distinct species within the lax-inflorescence group of this section. Also the placement of A. sciureus var. subsessilis was found to be wrong and this taxon should be treated as a synonym within A. kohrudicus.
