 or scabrid on the branchlets as in the type, and they are sometimes 

 bifariously hairy on the branches.

Engler, loc. cit., retains A. Richard's name of this species, and thereby 

 implicitly rejects that of De Candolle ; the latter name, however, 

 properly stands for the plant so named and characterized by Cruse, 

 Rub. Cap. p. 8 (1825).
