--><p>Senegalia is separated from related genera by the presence of prickles, the absence of stipular spines, a nectiferous disk at the base of the stipitate ovary, and portate pollen. Based on morphological evidence, L. Pedley (1978, 1986) separated Senegalia from other members of Acacia in the broad sense. The separation was further supported by phylogenetic analysis of chloroplast matK and trnl sequence datasets, in which species of Senegalia formed a monophyletic clade (D. S. Seigler et al. 2006b).</p>
