with 2 or 3 pair of leaflets; petioles clothed with short
hairs, mostnumerous in the axils of the leaflets; channelled
on the upper side and rounded on the lower, terminated beyond

sessile, broadly ovate, oblique, rounded at the base, taper-
pointed, smooth and glossy, but bearing a few short hairs,
slightly fringed at the edges, pennately nerved with strong
nerves, that are much branched. Stipules broadly ovate, obliquely
cordate at the base, sometimes semisagittate, taper-
pointed, entire, much veined, the veins branching, the margins
fringed with short hairs. Peduncles axillary, about the length
of the leaves, nearly cylindrical, slightly pubescent. Racemes
