along with 4. pachypus. Apparently loosely czespitose from a 
much branched woody base, two to five inches high or more, 
stems rather slender though not for the size of the plant, nodes 
one-fourth to one-half inch apart, or even closer; stipules 
rather large for the plant, scarious, ovate, almost connate, free; 
stems three to five inches long, ascending or some of them 
horizontal, almost glabrous; leaves two to three inches long with 
petiole which is nearly one-half the length; leaflets eight to 
twelve pairs, one-fourth inch or less apart, truncate or emar- 
ginate, oblanceolate to oval, one to four lines long, very decidedly 
petiolulate, very sparsely pilose, or almost glabrous, the leaves 
are so small that though the hairs are short they are still long 
for the size of the leaf; peduncles slender, shorter than the 
petiole and far overtopped by the uppermost leaves which are not 
at all reduced but are the largest of all; flowers subcapitate, five to 
twelve, on slender pedicels which are one to one and one-half lines 
long and twice the length of the ovate, hyaline, rather pilose bract; 
flowers horizontal, four lines long, ochroleucous in the dried 
specimen; calyx tube campanulate, one and one-half lines long, 
a little longer than the subulate lobes, whitish, rather densely 
short-hairy and canescent; banner very wide at base and narrower 
upwards, emarginate, bent at a right angle and erect, a line 
longer than the keel; keel nearly straight but tip incurved at a 
right angle and acuminate, the erect part nearly as long as the 
rest of the blade; wings apparently lanceolate, ascending and 
little exceeding the bend in the keel; pod apparently horizontal 
or reflexed, fleshy, coriaceous, one-celled, neither suture 
impressed but both very thick and prominent and rounded 
externally, pod minutely and sparsely pubescent when mature, or 
glabrous, faintly corrugated, abruptly acute with a stout beak 
and almost acute at the sessile base, six lines long or less, half 
oval to almost elliptical, ventral suture nearly straight, dorsal 
arched, apparently a little compressed when young but nearly 
round thereafter in cross-section, faintly bisulcate on the ventral 
side but the obcompressed appearance is doubtless due to the 
pressing, as other pods are as markedly compressed from the same 
cause. The flowers and pods lie among the leaves but are not 
concealed by them, usually only two to four pods mature on the
