Rhytidomene Rydb. (1919)

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]

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[edit]

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[edit]

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

Notes[edit]

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