Lower Guinea. Angola: Mulondo, on the River Cunene, Newton ! 
This has the habit of D. radicans, and may be a wet-forest form of it. 
7. D. multicaulis, 0. Kuntze, Rev. Gen. 486. Branches many, 
16 in. long, rather stout, hairy; leaves up to 2 by ? in. Stamens 4,

Except by the stouter straighter stems and larger leaves, this hardly differs from 
D, radicans, 
8. D. nobilior, C. B. Clarke. Sparingly shortly hairy, branches 
34 ft. long, stout, straight, little-divided. Leaves 13 by 3-1 in. (exclu-

Lower Guinea. Angola: Pungo Andongo, Welwitsch, 5107! 5158! 
Mozamb. Dist. German East Africa: Usambara; Duga, Holst, 3204a! 
Welwitsch (5158) has small flowers and cannot be united with D. Hildebrandt, 
and with this the other examples (without flowers) cited match, 
9. D. nudanthera, C. B. Clarke. Scabrous; branches 8-14 in. 
Leaves 14 by } in., lanceolate, subacute at both ends, hispid : petiole
