title: [A taxonomic study on the original plant of radix astragali].
abstract: There are dispute about the status of taxonomy among Astragalus membranaceus (Fisch.) Bge, A. membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao. and A. pallidipurpureus stat. nov. The varieties and taxa of the complex are still in need of revision. With molecular biology study used trnH-psbA intergenic region, the taxonomic revision of Radix Astragali has been made. A. pallidipurpureus stat. nov is suggested as a new species.
