lescent. Peduncles nearly always shorter than the leaves. 
Flants with conspicuous stems. Flowers red-purple. 
180 inflexus. 
Plants almost stemless. Flowers mostly white. 181 Purshii. 
161 Astragalus Webberi Gray Bot. Cal. 1154 (1876). Pods with 
both sutures raised externally and the ventral much thickened when 
dry, narrowly-oblong but a little narrowed at both ends, smooth, 5-7 
mm. high, 10-12 mm. wide, generally sulcate to the middle but not at 
the ends, tips broadly triangular and a little laterally flattened, cross- 
section reniform to oblately obovate. Flowers white, 1.5 cm. long, 
spreading. Banner elongated and almost erect, narrow, 8-9 mm. long. 
Wings narrowly oblong, arched to 45 degrees, rounded, about 4 mm. 
shorter than banner and as much longer then keel or less. Keel about 
4 mm. high, straight the end abruptly erect and forming nearly a right 
angle, purple. Calyx tube about 7 mm. long, attached in line with the 
base, the upper side a little arched, the lower side straight, the teeth 
subulate and nearly half as long as the tube. Bracts as long as to a 
half longer than the short pedicels, lanceolate to ovate. Peduncles 
longer than the leaves. Heads rather densely 9-20 flowered. Proper 
petioles rarely as long as the lowest leaflet. Leaflets 5-10 pairs, nar- 
rowly oblong-oblanceolate, with cuneate and long-petiolulate base, 
not over 2 cm. long, not retuse, variably silvery-pubescent. This oc- 
curs sparingly on hillsides in the Sierras near Sierra Valley California 
in the Middle Temperate life zone. It is probably only a marked form 
of A. cibarius. 
152 Astragalus cibarius Sheldon Minn, Bot. Stud. 9 149 (1894). A. 
iodanthus Watson in part, as to Utah material. Pods puberuient to 
almost sınooth, rather abruptly narrowed and substipitate at base the 
stipe from barely longer than wide to 2 mm. long and not jointed to 
the calyx, pods from nearly straight to arched almost to a half circle, 
2.5-4 em. lorg, 7-10 mm. wide, 5-8 mm. high, oblong to broadly linear, 
finely corrugated, not mottled, tip froma little to much flattened, tri- 
angular, walls about 3 mm. thick when fresh the inner one woody, 
cross section from nearly round to almost didymous by being much 
obcompressed. the normal cross-section is nearly ©-shaped but the 
sutures not touching, and the ventral suture raised externally and not 
intruded and only slightly thickened, dorsal sutures raised externally 
as a thin line when dry and intruded as high as wide in forms with 
deltoid cross-section, pods often much sulcate along the micdle. The 
flowers purple, bluish when dry with lighter claws, albino forms rare, 
1.5-2 cm long, almost sessile, with conspicuous lanceolate bracts near- 
ly half s'ong as calyx. Banner ovate, about 1 cm. long, rather deep- 
ly notched, with sides much reflexed below so that the banner seems 
oblong. arched beyond the calyx tips to nearly and rather sharply e- 
rect, white spot deep-purple-veined and conspicuous, blade deep- 
purple below and shading to white above or purple throughout, a little 
sulcate. Wings from nearly as long as banner to 4-6 mm. shorter but 
much longer and narrower than keel, nearly linear, very rounded,a 
trifle narrowed in the middle and a little enlarged above, mostly about 
straight, but sometimes arched to 30 degrees, variably purple at base, 
white above, rarely purpie throughout, flaring at tip and the ends 
turned to horizontal, obscurely erose or notched. Keel about 5 mm. 
long and 4 mm. high, the base straight and then abruptly arched to | 
erect and with tip very obtuse, rounded, and deep-purple. Calyx ni- 
grescent, with tube about 4-5 mm. long and nearly half as high, cleft 
deeper above, and triangular teeth about one fourth as long. Pedun- 
cles normally shorter than the leaves, rarely longer, stout, with the 
pods shortly racemose. Leaves with petioles mostly twice as long as 
the lower leaflets. Leaflets about 9-12 pairs, from oval-ovate or ob- 
bu ovate to cuneate-oblong, mostly notched. about 1 cm. long, rarely 2 
cm. long when over developed, siender-petioled, green above, not -
