Vachellia Hebeclada
''Vachellia'' is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus ''Acacia'' until 2009. ''Vachellia'' can be distinguished from other acacias by its capitate inflorescences and spinescent stipules.

The wide-ranging genus occurs in a variety of open, tropical to subtropical habitats, and is locally dominant. In parts of Africa, ''Vachellia'' species are shaped progressively by grazing animals of increasing size and height, such as gazelle, gerenuk, and giraffe. The genus in Africa has thus developed thorns in defence against such herbivory. Nomenclature By 2005, taxonomists had decided that ''Acacia sensu lato' ...
