Orbexilum, commonly called leather-root, is a genus of flowering plants in the legume family (Fabaceae). They are native to North America, where they are found in the United States and Mexico, south to Chiapas.
This genus can be distinguished from other genera in the Psoraleeae by its "thick glabrous pod walls that are distinctively rugose and by [a] calyx that is scarcely accrescent."




Taxonomy


The genus was described by Constantine Samuel Rafinesque in 1832, with the type species O. latifolia, moved from Psoralea. (O. latifolia is now considered a synonym of O. onobrychis.) Rafinesque differentiated Orbexilum from Psoralea largely on the basis of features of the calyx.
