Abstract	Introduction The sect. Hymenostegis Bunge seems to be a disagreement section with its number of species in the genus Astragalus. The first revision of this section with 26 species established by Bunge (1868). Later on, present author during the local revision for Astragalus in Iran increased the number of species to 35 distinct taxa (Maassoumi 1995). This critical work was not also confidence for specialists, in this reason the section was revised again (Zarre & Podlech 1996), unfortunately, these authors without studying of the type of recent species, unreasonably reduced the number of taxa. Finally for preparing Flora Iranica treatment (Podlech & Maassoumi 2001) revised the section again with new collections. In this work with describing more new taxa, the number of species increased to about 40 distinct species. Recently three more new species were described (Podlech 2003; Ghahremani nejad 2004). Finally, another new species is described by the author. So, with this short historic introduction it seems that with new collections, the number of taxa will be increased. Recently the new molecular analysis of the section on some species, showed that this section is a monophyletic and homogenous section in the genus. The sect. Dissitiflori DC. for flora Iranica area was recently revised (Podlech, unpublished). This work covered a great number of species in which the majorities belong to Afghanistan territory. According to Fl. USSR sect. Corethron Bunge is closely related to sect. Disitiflori DC. But the shape of fruit with having oblong elliptic pods and long spreading hairs seems to be a distinct section, but new molecular analysis (Kazempour & Maassoumi, unpublish) with using A. dendroproselius Rech. f. in cladogram nested with other species of sect. Dissitiflori DC. So, it will be reasonable to reduce sect. Corethron as a synonymous of sect. Dissitiflori DC. as Podlech treated.
