| Astragalus kolymensis Jurtz. | |
| Publ. & Syn. | Jurtz., Fl. Suntar-Khayata: 182 (1968). Holotype (LE): Siberia: Yakutia, "ad fl. Kolyma, in ripa dextera, 130 leucas ross. infra Sredne-Kolymsk, in loco docto Banski kamen", 19. June 1875, leg. Th. Augustinovicz. |
| Notes | Murray and Elven: We found Astragalus kolymensis morphologically close to A. tugarinovii and also sympatric with it in Chukotka. Yurtsev confirmed the sympatry but stated that the former sharply differs from the latter in very short, flat, appressed and scale-like scattered hairs and almost filiform calyx teeth, in edaphic preference (A. kolymensis on acidic rocks, A. tugarinovii on circumneutral to basic rocks) and also in ploidy levels. He considered, however, A. kolymensis to have been derived from A. tugarinovii. |
