The plant figured by T. R. Sim (Forest Flora of Cape Colony, t. 59)

Plukenet’s type of Mimosa madraspatana, upon which Linnaeus 
partly founded his Mimosa horrida ( Acacia horrida, Willd.), is a form 
of the Indian species, A. eburnea, Willd. It has therefore been 
necessary to find another name for the South African plant, and 
A. Karroo, Hayne, the next available name, has been reinstated.
