Mulford’s Milkvetch (Astragulus mulforidiae)
Discovered by Isabel Mulford in the Boise foothills in 1892, this rare member of the pea family is now known from three widely separated areas in southwestern Idaho and adjacent Oregon (Kennison 1980; Moseley 1989). It is, however, declining in all areas, with the destruction of its habitat in the Boise Foothills being particularly acute.
