those on the flowering part of the stem reduced to linear rudiments, 
1-1} lin. long, densely puberulous. Flowers from the axils of the upper 
part of the plant or axillary and terminal, solitary or in pairs or on

the middle of the base of the corolla-lobes are 5 small fleshy tubercles, 
Stamens much exserted, 3 as long as the coronal-lobes ; filaments 1} lin. 
long, broadly dilated at the base and rather broad in the upper part 
where attached to the dilated part of the style; anthers 1 lin. long;
