Asymmetrical karyotype

The karyotype analyses and chromosomal data of 25 taxa belonging to the sections Macrophyllium, Hymenostegis, Hymenocoleus, and Anthylloidei of the genus Astragalus naturally distributed in Turkey are described. The cytogenetic data obtained were evaluated systematically. The following somatic chromosome numbers were found: 2n = 16 for A. oleaefolius, A. dipodurus, A. cephalotes, and A. yukselii; 2n = 32 for A. longifolius; and 2n = 48 for A. isauricus in the sect. Macrophyllium; 2n = 16 for A. zohrabi, A. sosnowskyi, A. velenovskyi, A. trifoliastrum, and A. uraniolimneus; 2n = 18 for A.
