leaflets submembranous, flat, ascending, glaucous green beneath, 
dull darker green on the upper surface, glabrous, 12.5 mm. 
long, 4 mm. wide, entire, oblong elliptic, both ends rounded,

Inflorescence terminal or from the uppermost leaf axils,

693 
sprinkled with white lenticels especially toward the base, |
