Orbexilum ( Anglèis )

fornì da wikipedia EN

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

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]

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

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