Montana distribution: Carter, Cascade, Choteau, Fergus, Golden Valley, Powder River, and Rosebud counties. Carter County distribution: One population was found in 1997 on BLM land along the Powderville Road west of Chalk Buttes. Psoralea hypogaea Little Indian Breadroot. HABITAT: The Carter County population is in a small blowout below the crest of a sandy ridge. It is associated with prairie sandreed (Calamovilfa longifolia) and sand bladderpod {Lesquerella arenosa). SPECIES BIOLOGY: Little Indian breadroot is a long-lived perennial with a deeply buried root that enables it to survive burial or loss of surface material associated with wind erosion. This species is now known from seven counties in Montana, a relatively large number, with many new records wince it was first reported to the BLM (Heidel 1994). But its population numbers are usually very low. The Carter County population had only six plants. OTHER COMMENTS: The breadth of speciesi distribution and its occupancy in tiny areas of suitable habitat suggests that this species may not be warranting the S2 (state imperiled) rank. Its state rank is likely to change in the future, but this change will be made based on documentation rather than projection. This is one of several sand-loving species in the county that are often found with other species of special concern where the habitat is extensive and/or in good condition. 103.
