Xerocladia is most closely related to Prosopis. They both have stipular spines, leaves with few pairs of pinnae, and 10 stamens. In contrast to Xerocladia, Prosopis usually has a spicate inflorescence instead of a capitulum, an elongate straight or spiral legume pod which is not winged. Prosopis also has more (18-30) leaflets per rachilla, and leaflets opposite or sub opposite rather than alternate. (from
