This is very likely identical with Z. lucida var. hispida, Hallier (see p. 59). 
The latex is worthless.

_ According to De Wildeman and Gentil, this is one of the commonest rubber 
vines of the Congo Free State, extending westwards to Boma. The caoutchoue 
prepared from the latex is black and said to be of excellent quality. Dawe, who 
found it in the Dumu Forest, Buddu, at 4000 ft., also considers it as one of the best 
rubber plants of Uganda.
