A somewhat gregarious, flat- neared tree 15-20 ft. high, with 
smooth bark, closely allied to A. heteracantha, Burch., but with 
spirally twisted pods, and bracts close to the base of the peduncle. 
Flowers creamy-w ite, “ very sweetly scented.” The tree An 
a gum; the wood is considered to be fit only for fuel. In t 
Waterberg District of the Transvaal, the ‘ steenbok ’ are said to me 
very fond of the pods and also Bi eat ee leaves; but cattle do 
not appear to eat the pods, as far as my observation goes, 
though very fond of those of A. giraffae, Burch., and A. Benthamii, 
Rochebr. 
In the winter of 1912, the centenary of Burchell’s visit, 
I went to Litakun, partly with a view to re-collecting Acacia 
litakunensis, Burch., in the type locality. 
ee species of Acacia were common there, including the 
well-known A. giraffae, Burch. and A. robusta, Burch. There 
were also large, old trees of a flat-crowned species with dimorphic 
spines and much twisted pods which agrees with Burchell’s 
description and figure and with the scrappy type-specimen of 
A. litakunensis, so there can be no doubt that it is the tree 
described by Burchell. It agrees also with A. spirocarpoides, 
Engl., which therefore becomes a synonym.
