ascending, ashy. Flowers 4-5 mm. long. Banner oval, about 3 
mm. long, with sides reflexed about % mm. wide below, abruptly 
erect at end of tube, waterlined, often seemingly fiddle-shaped; 
groove U-shaped and very broad and filling the whole banner above. 
Wings oblong, arched 30°, about 1 mm. wide, about as long as ban- 
ner, or 2 mm. shorter, oblique and obtuse at tip, the right hand 
one incurved over keel, the other flaring, tips connivent, 2 mm. 
longer than keel. Keel half-oval-obovate, about 2 mm. long, obtuse. 
Calyx a little over 1 mm. long, reddish, with acutish base, ashy, 
' rather shorter than the subulate and curved teeth, on a slender 
pedicel about 1 mm. long which equals the linear and thin bract.' 
Peduncles axillary throughout, often twin, about 2 cm.-long, filiform. 
Leaves 3-4 cm. long, wide, the upper ones sessile. Leaflets about 
6 pairs, seemingly linear but narrowly to broadly elliptical, obtuse, 
rather thin, slender-petiolulate and rather cuneate at base, about 1 
em. long above, appearing green especially above but minutely pu- 
bescent. Stems 1-3 ft. long, prostrate in wide mats, many, simple 
above, freely branched below, straight, with internodes a little 
shorter than the leaves. Stipules triangular, green, about 4 mm. 
long, not connate. Root thick, rather fleshy and erect. Stems 
herbaceous to the very base. From Chat to Yreka California, grow-

mucro, obcompressed below, with cross section reniform, shining 
when ripe and finely cross-nerved, opening throughout at both su- 
tures, reflexed, broadly sulcate dorsally to the middle. Flowers 
linear to cuneate-linear, blunt, about 8-15 mm. long, ashy with very
