mm. long, wide, spreading. Banner about 4 mm. long, oval, arched’ 
abruptly at calyx tips to 45°, with sides reflexed about 1 mm. wide,. 
about 2 mm. longer than keel. Wings obliquely lanceolate and 
arched a little, about 1 mm. wide, much narrower than keel and. 
about as long. Keel large, nearly 4 mm. long and high, a little con- 
vex along the base and much rounded and very obtuse, the whole 
forming almost a half circle, much separated from banner. Calyx 
tube about 3 mm. long, acutish and narrowed at base, about equally 
inserted, oblique and deeper cleft above, with rather sharp sinuses. 
and triangular teeth fully half as long as tube, very closely ap- 
pressed hoary. Pedicels stout, about 1 mm. long and as long as the 
triangular bracts. Peduncles axillary, slender, 5-7 cm. long, shorter 
than the leaves, ascending as are the leaves, the floral rachis much - 
shorter. Leaves about 1 dm. long or less, the petiole about half 
the whole, the rachis tapering but litile. Leaflets 3-5 pairs, about 
oval-obovate, rounded, thick, ftat, shortly cuneate below, about 1 em. 
long, distant, silvery-hoary with flat, broad, rough, tapering and. 
closely appressed hairs. Stipules deltoid, very small and green, 
2-3 mm. long. Stems very many from the crown of the slender and. 
erect root, rather stout for the plant, flexuous, the many internodes 
rarely 3 cm. long, prostrate, a few inches to 2 ft. long. Winter an- 
nuals. Whole plant hoary. In rocky gulches along creek beds, In- 
dian Spring Charleston Mts. to the Mojave desert. Tropical.

Pods including stipe fully 3 cm. long, abruptly contracted at both 
ends and then tapering into a long tip and base, triangular-cordate 
in cross section to broadly deltoid, mostly as wide as high, shallow- 
sulcate dorsally, completely 2-celied, chartaceous, with a flat and 
ensiform tip a little declined, the ventral suture concave in the 
middle and convex a little above, raised and thickened and with a 
thin and slightly raised edge aiong the middle, the body finely 
reticulated, minutely woolly at first, half-narrowly-elliptical, becom- 
ing smooth, the beak 3-6 mm. long and straight, the stout stipe as: 
long as to 3 times as long as calyx tube. Flowers dirty white, be- 
coming yellowish, about 1 em. long, several. Banner about 7 mm. P 
long, oblong-oval, arched abruptly to 457-60? from calyx tips, with —— 
sides reflexed, about 2 mm. longer than wings. Wings 2 mm. longer 
than keel, oblong-lanceolate, obtuse, arched to 45°, about 2 mm. 
wide. Keel very wide and blunt, about 4 mm. long and 3 mm. 
high, the tip only a little higher than the rest and rather truncate, | 
~ erect and rounded sharply from near the base, not purple, with a — 
minute out-turned boss at the end. Calyx tube about 4 mm. long 
and 3 mm. high, a little narrowed at base and acutish, and attached - 
. to the slender pedicel near the corner, oblique at tip, cleft deeper — 
. above and with broad sinuses, the teeth triangular and a little shor- 
ter than the tube, nigrescent.  Pediceis in truit 2-3 mm. long, re- | 
curved, mostly longer ¿han the minute bracts.. Peduncles in the type. 
longer than the leaves, strict and stout, about 1 dm. long, the fruit- 
ing rachis hardly half as long. Leaves 5-7 cm. long, the upper ses- 
sile, with 8-9 pairs of linear-elliptical leaflets nearly contiguous 
- and obtuse and long-petiolulate and cuneate, at base. Stipule 
ves er thick, about 7 — a hatin ascending, ze u. sle
