 leaflets (1' long) thick and rigid, oblong-oval, obtuse or emarginate at both ends,

 cle nearly to its base; corolla 2-3 times the length of the acuminate hairy calyx- 

 lobes ; legume coriaceous, compressed, falcate, thickened at tiie sutures, sprinkled 

 wth short appresscd hairs, 6 - 10-seeded. — Varies with a stouter more pubescent 

 and almost villous stem, larger (1^' - 2'), thinner, and mostly acute leaflets, longer

 the upper ones acute; racemes single, about twice the lengtli of the leaves, the
