Orbexilum, commonly called leather-root, [2] 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. [3]

Contents

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." [4]

Taxonomy

The genus was described by Constantine Samuel Rafinesque in 1832, with the type species O. latifolia, moved from Psoralea . [5] (O. latifolia is now considered a synonym of O. onobrychis. [6] ) Rafinesque differentiated Orbexilum from Psoralea largely on the basis of features of the calyx. [7]

Species

Orbexilum comprises the following species: [1] [4]

Notes

  1. ↑ The specific epithet is sometimes incorrectly spelled lupinellum, but is a noun in apposition, so is correctly spelled lupinellus. [9]
