Abstract
Astragalus Linnaeus (1753: 755) (Fabaceae), with about 240 sections and 3000 species, is the largest genus of flowering plants (Podlech & Zarre 2013). Sect. Hypoglottidei De Candolle (1825: 281) with 46 species is one of the taxonomically most problematic sections. The majority of these species grow in Turkey and Iran (Chamberlain & Matthews 1970; Podlech et al. 2010; Podlech & Zarre 2013). Astragalus saganlugensis Trautvetter (1858: 323) is common in both countries, but also in Armenia and Azerbaijan. Trautvetter (1858) described this species as a member of section Hypoglottidei, but did not designate type material for the species. Podlech and Sytin (1996) were the first to choose a lectotype for this species.
