suture, the marginal keels scarcely exceeding the upper suture im 
height, valves coriaceous, somewhat acuminate, sparingly ferru- 
ginous-pubescent, shehtly horizontally suleate between the seeds ;.

British North Borneo, Sandakan, Ramos 1511 (type), Septem-— 
ber, 1920. In damp thickets at low altitudes. The same species 
rs represented by Native Collector 367, 1693, Bur. Sci. from the 
vicinity of Kuching, Sarawak. A species well characterized by its. 
ferruginous indumentum: its conspicuously bracteolate flowers; 
and its compressed, comparatively narrow, transversely sulcate,,. 
sparingly ferruginous-pubescent pods, the keels along the upper: 
suture being exactly marginal,
