Nomenclature
By 2005, taxonomists had decided that '' Acacia sensu lato'' should be split into at least five separate genera. The ICN dictated that under these circumstances, the name of ''Acacia'' should remain with the original

Description
The members of ''Vachellia'' are trees or shrubs, sometimes climbing, and are always armed. Younger plants, especially, are armed with spines which are modified stipules, situated near the leaf bases. Some (''cf''. '' V. tortilis'', ', '' V. luederitzii'' and '' V. reficiens'') are also armed with paired, recurved prickles (in addition to the spines). The leaves are alternate and bipinnately arranged, and their pinnae are usually opposite. The racemose inflorescences usually grow from the leaf axils. The yellow or creamy white flowers are produced in spherical heads, or seldom in elongate spikes, which is the general rule in the related genus ''
Senegalia
''Senegalia'' (from Senegal and ''Acacia senegal'' (L.) Willd.) is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of ''Acacia.''
The genus was considered polyp ...
''. The flowers are typically bisexual with numerous stamens, but unisexual flowers have been noted in '' V. nilotica'' (''cf''. Sinha, 1971). The calyx and corolla are usually 4 to 5-lobed. Glands are usually present on the rachis and the upper side of the petiole. The seed pod may be straight, curved or curled, and either dehiscent or indehiscent.
