Psoralea is a genus in the legume family (Fabaceae). Although most species are poisonous, the starchy roots of P. esculenta (breadroot, tipsin, or prairie turnip) and P. hypogaea are edible. A few species form tumbleweeds.

Common names include tumble-weed (P lanceolata),[1] and white tumbleweed.[2]
