none but shorter than the obscure and ovate bract.  Peduncles

41. Astragalus metanus Jones. Cont 7 666, 733 (1895). Pods 
decidedly laterally compressed, lenticular, much the shape of the 
montanus group, obliquely ovate-elliptical, upper one third vetchlike, 
lower part swelled out by the few seeds, minutely puberulent, 10 mm. 
long, 5 mm. high, tip deltoid to triangular-acute, ventral suture nearly 
straight, narrowed at very base, cross section oval near the: base. 
Flowers racemose, nearly sessile, purple at tip, horizontal, about 7 mm. 
apart. Banner 7 mm, iong, bent abruptly 2 mm. beyond the calyx 
teeth to 45 to 90 degrees, oval, sides reflexed 1 mm. wide, most at 
base. Wings arched 30 to 60 degrees exposing the keel, oblong to 
oblong-lanceolate, 2 mm. shorter than the banner, narrower than the 
keel. Keel abruptly bent at tip to 110 degrees, about 1 mm. shorter 
than the wings, produced to a point, 3 mm. high, light-colored, with 
base a little arched. Calyx broadly campanulate; tube 2 mm. long, 
scarcely oblique at mouth; teeth triangular, about a third to half as 
long as tube. Pedicels not slender, 1 mm. long. Peduncles including 
rachis about a foot long, sulcate, normally 3-4 times as long as the 
leaves, often 5 dm. Jong. Leaves 10-15 cm, long with proper petiole 
23 cin long on the lower leaves and absent on the upper ones. 
Leaflets linear lanceolate, barely acute, not contiguous, 3-4 cm. long, 
thin. Internodes 7-10 cm. long. Stipules very small, green, 2 mm. 
long, reflexed, adnate, not connate. Stems prostrate from perennial 
roots, 2-3 ft. long, rather stout, sulcate. Plants minutely pubescent 
throughout with fine and appressed hairs fixed by the base. Hansen’s 
ranch, Lower California near the boundary, Orcutt, 
42. Astragalus Vaseyi Watson Proc. Am. Acad. 17 370 (1882). 
Pods obliquely ovate, often a little obcompressed below, flattened 
only at very tip which is short and deltoid, about 1 cm. wide, spicate, 
all on one side of the floral rachis as if pendent on ascending stems, 
2 cm. long, usually with a little boss at base, when inmature then 
often somewhat laterally compressed. Flowers spicate, the same as 
in A. metanus except that the calyx is campanulate and teeth as long 
as the tube. Peduneles with floral rachis rarely over twice as long as 
the leaves, not over 1.2 dm. long. Leaves rarely over 1 dm. long. 
Leaflets elliptical to narrowly so, flat, apiculate, rarely over 2 em, long. 
Internodes seldom over 2-3 cm. long. Plants slender, flexuous, (said to 
be) shrubby at base, silvery throughout with closely appressed hairs 
except the minutely puberulent pods. On the California desert south 
of the Mojave river and east of the Sierras, Tropical. 
43. Astragalus Thurberi Gray Pl. Thurber 312 (1855). Pods only 
minutely pubescent, about 6-8 mm. long, papery, faintly sulcate dorsally, 
nervose, rounded at base, widely spreading, with both sutures evi- 
dent, jointed to a minute stipe. Flowers 4-7 mm. long, purplish to 
ochroleucous, many. Calyx tube campanulate, not gibbous, about 2 
mm. long, teeth subulate and about as long as the tube. Bracts subu- 
late, 2 mm. long longer than the pedicels, leaves many, rather appres- 
sed. Petioles one third to one half the whole. Leaflets 5-7 pairs, 2-10 
mm. long, rather distant or crowded, narrowly oblong, obtuse, fleshy, 
retuse. Stipules triangular, adnate. Stems many spreading, rather 
| stout, about a foot long, with short internodes, wih many z
