the leaves; cross section, reniform. Flowers many, closely racemose, 
horizontai. Calyx campanulate-cylindric, 3-4 mm. long, a little oblique 
at the rounded base, not oblique above, with teeth minute and deltcid 
shortly pubescent. Pedicels rather slender, in fruit 2-3 mm. long and 
rather longer than the triangular bracts. Banner oval, about 8 mm. 
long, abruptly erect remote from calyx, with sides reflexed most below. 
` Wings obliquely oblong-oblanceolate and very obtuse, about 3-4 mm. 
shorter than the banner and a trifle longer than the keel. Keel 
with straight base, then abruptly arched to erect at the end and tip 
triangular and acute. Leaves 1-1.5 dm. long, narrow, nearly sessile 
with 12-15 pairs of elliptical and obtuse and rather distant leaflets 
about 1 cm. long, thick and green, smooth. Stems 4-6 ft. high, branched 
above and flexuous and rather slender. Growing in the alkaline val- : 
leys east of San Diego California, seldom seen. Tropical.

(1864). Phaca macrodon H. & A. Bot. Beech, 333 (1841). A. holo- 
sericeus Jones. Pods oval-ovate to half-oval, 2-3 cm. long and about 
2 cm. wide, the oblique tip deltoid and short, a little sulcate at both 
sutures, chartaceous, spreading to reflexed, the cross section about 
round. . Flowers ascending, nearly white, about 7 mm. long, 10-20 in a 
short and close raceme. Banner round, gently arched to erect from 
the calyx tube, with sides reflexed above, about 4 mm. long, barely 
longer than wings. Wings half-oval, a trifle longer than keel. Keel 
arched to a half circle from base, the triangular and produced tip as 
long as base and erect, about 4 mm. high. Calyx tube campanulate, 
about 3 mm. long, with subulate and curved teeth nearly as long. 
Bracts ovate, minute, shorter than the pedicels which are 2-3 mm. long. 
Peduncles slender, about half as long as leaves, the fruiting rachis 
at least as long. Lower leaves much reduced, the upper 1-1.5 dm. long, 
with petioles mostly 2-3 cm. long. Lower leaflets 5-7 pairs, linear-el- 
liptical, acute, 7. mm. long, and petiole as long as leaf rachis; upper 
leaflets about 10 pairs, linear-lanceolate, very acute, 1-2 cm. long. Stip- 
ules subulate-filiform, 7 mm. long, reflexed, thick, not connate. Inter- 
nodes 2-5 cm, long. Stems rather flexuous and slender. Pubescence 
very soft and short-shaggy throughout with very fine wavy hairs and 
seeming woolly but hardly so. Stems and pods less pubescent. Mon- 
tery Co., San Luis Obispo and the coast region, also at Fresno and 
around the San Joaquin valley.

(1864). Phaca T. & G. Fl. 1 346 (1838). A very variable species. 
Pods papery, 2-4 em. long and about 3 cm. wide, in the type, gibbous- 
ovate to half oval, apiculate. Flowers cream-colored, rather reddish 
in. bud.- Banner oval-ovate, about 7 mm. high, abruptly arched at 
end of calyx to erect, with sides reflexed near the base and 1 mm. 
wide; groove sharply widened at end of keel till it fills the whole 
banner, the banner tips not reflexed. Wings sharply arched to 
pearly erect and exposing keel, very obliquely cuneate obovate, about 3 
mm.: wide near tip, very blunt, the right hand one flaring below, the 
other close pressed to keel, about 1 mm. longer than keel and 3 mm. 
shorter than banner. Keel as high as long and abruptly rounded to 
a little more than erect and sharp, about 3 mm. high, not dark-tipped. 
Calyx nearly hemispherical, oblique. at both ends ,inserted near the 
lower corner and fleshy at corner, at mouth obcompressed and deeper 
and broader cleft. Upper teeth the longer, subulate, rather deltoid, 
hardly one-third as long as tube. Flowering pedicels about equaled 
by the ovate bracts, 1-2 mm. long. Peduncles slender, rarely 1 dm. 
long. Leaves narrow, 1-1.5 dm. long, all somewhat petioled. Leaflets 
10-13 pairs, 7-20 mm. long, narrowly elliptical to linear-oblong, obtuse, 
_ rather thick, about 4 mm. wide, shortly petiolulate, inclined to be sil- 
_ very below with very fine straight and closely appressed hairs, but
