Hymenocoleus Bunge, sect. Hymenostegis Bunge, and sect. Macrophyllium Boiss. belonging to Astragalus L. in Turkey is given based on a revisional study carried out in Turkey. As a result of this study, an account of 19 species including keys and general distribution as well as their conservation status in Turkey is given. It is determined that A. narmanicus Karaman & Aytaç is new to science and A. expetitus Maassoumi, A. pereshkhoranicus Maassoumi & ., and A. marivanensis Maassoumi & Podlech do not exist in Turkey. Additionally, the name of the sect. Hymenocoleus is preserved. Key words: Astragalus, section, conspectus, Turkey 1. Introduction The genus Astragalus L. (Fabaceae) has approximately 3000 taxa around the world. The genus is known to spread vigorously in cold, semiarid, and arid regions of the Old World (approximately 2400 species); in western regions of North America (about 450 species); and especially along the Andean Mountains in South America (about 100 species) (Maassoumi, 1998; Podlech and Zarre, 2013). Astragalus section Hymenostegis was first named by Bunge (1868–1869) in his revision, entitled “Generis Astragali species gerontogeae” under the subgenus Calyphysa. This section was revised by Rechinger et al. (1958) and then was included in the Flora of Turkey (Chamberlain and Matthews, 1970), Flora of USSR (Gontscharov, 1946)
