| Astragalus alpinus subsp. alaskanus Hultén | |
| Publ. & Syn. | Astragalus subpolaris Boriss. & Schischk., Fl. URSS 12: 44 (1946). Nomen novum for Phaca lapponica DC., Prodr. 2: 274 (1825), non Astragalus lapponicus Burnat (1912). Described from arctic Europe and Siberia. Type probably in G-DC. |
| Notes | Elven and Murray: We consider subsp. alaskanus in the restricted meaning of Hultén (1947), excluding the majority of Asian plants until they are better documented, and also excluding the more northern North American plants. Hultén considered subsp. alaskanus to be a Cordilleran race and to be absent from northern Alaska and the Yukon Territory. The material in ALA suggests otherwise. The race is nearly confined to Alaska and the Yukon Territory and replaced by subsp. alpinus in the Wrangell-St. Elias mountains in eastern south-central Alaska and the southwestern and southeastern Yukon Territory, and in the Rocky Mountains farther south. |
