Flowers of B. ugandensis were found in whieh the filaments 
of three or of all four stamens were short (8-9 mm. long), thick, 
and densely tomentose ; the anthers were slightly broader (2 mm. 
broad) than in the normal flowers; both ovary and dise were 
larger than in normal flowers, aud the dise was densely tomentose 
instead of being glabrous.
