Sylva Tellur.,111. 1838
Introduced; South America, introduced worldwide in tropical and warm-temperate regions.
Species 33 (2 in the flora).
Traditionally included in a broad circumscription of Cleome, Tarenaya is distinguished by its stipular and petiolar spines, absence of arils, and seeds with a large cleft cavity. All species are native to tropical America, with the exception of T. afrospina (H. H. Iltis) H. H. Iltis, of western Africa. Tarenaya hassleriana, long known as C. spinosa (and commonly by the misapplied name C. houtteana) and more recently as C. hassleriana, is a popular garden ornamental and, probably, the most widely distributed member of the family.
