Astragalus is one of the largest genera of angiosperms and a characteristic component of the steppes and mountains of North Asia. Here, we used scanning electron microscopy to investigate the seed morphology of 56 species of the genus from North Asia. In Astragalus , seed color varies from yellow-green, greenish brown, reddish brown to grayish brown. Seed shapes include reniform- globose, rombiform, and oblong-elliptical. Seed sizes vary from 1.25 x 0.88 mm to 4.94 x 3.29 mm. Anticlinal walls are straight, undulate, or slightly thickened, and the periclinal walls are aveolate, stellate, pectinate, or rugose. We recognized two main types …

The present study is focused on several species from the genus Astragalus L. with the aim to clarify the taxonomic status of Ukrainian local endemic species Astragalus borysthenicus Klokov, which is sometimes considered a synonym to A. onobrychis L. In this study, the morphological features, current taxonomy, taxonomical history, and phylogenetic analysis based on rDNA Bayesian inference, as well as comparative analysis of ITS1 and ITS2 secondary structures, were investigated. It was found that A. borysthenicus is distant from A. onobrychis according to phylogenetic analysis. Moreover, A. borysthenicus has differences from the investigated taxa in its secondary structures of ITS1 …
