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]
- Orbexilum chiapasanum B.L.Turner
- Orbexilum lupinellus (Michx.) Isely[note 1]
- †Orbexilum macrophyllum (Rowlee) Rydb. – bigleaf scurfpea[8]
- Orbexilum melanocarpum (Benth.) Rydb.
- Orbexilum oliganthum (Brandegee) B.L.Turner
- Orbexilum onobrychis (Nutt.) Rydb.
- Orbexilum pedunculatum (Mill.) Rydb.
- Orbexilum psoralioides (Walter) Vincent, syn. Orbexilum gracile (Torr. & A.Gray) B.L.Turner
- Orbexilum simplex (Nutt. ex Torr. & A.Gray) Rydb.
- †Orbexilum stipulatum (Torr. & A.Gray) Rydb.
- Orbexilum virgatum (Nutt.) Rydb.
Notes
[edit]- ^ The specific epithet is sometimes incorrectly spelled lupinellum, but is a noun in apposition, so is correctly spelled lupinellus.[9]
