Astragalus lentiginosus var. iodanthus, synonym Astragalus iodanthus, is a variety of Astragalus lentiginosus, a flowering plant in the legume family, Fabaceae.[1] It is known by the common names Humboldt River milkvetch[2] and violet milkvetch.[3] It is native to the western United States, where its range includes California, Idaho, Nevada, Oregon, and Utah.[3] It grows on hills and in valleys[4] in barren sandy and volcanic soils[5] in habitat such as sagebrush.[6]

This perennial herb produces several prostrate stems up to 40 centimeters long. The compound leaves are made up of 9 to 21 rounded or teardrop-shaped leaflets each up to 1.8 centimeters long. The inflorescence is a raceme of flowers in shades of reddish purple or white to cream with a purple tip on the keel petal. There are up to 25 flowers in a raceme, and they are crowded when first blooming but spread out over time. The fruit is a legume pod up to 4 centimeters long, becoming dark, mottled, and papery to leathery with age.[7][8]
