Xiphotheca

Xiphotheca is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae. The name of the genus is a compound of Ancient Greek ξίφος (ksíphos), which means "sword", and θήκη (thēkē) which can mean "box" or "sheath"—a reference to the shape of the legume pods.[3] Members of this genus can be distinguished by:

"(1) the presence of bracteoles in most species; (2) the fusion of the bracts with the base of the pedicel; (3) the laterally compressed pods; and (4) the accumulation of anabasine as a major alkaloid."[3]
