126. Astragalus Salmonis Jones Cont, 8 9 (1898). Referred to 
A. Bourgovii by Watson and Gray. Young pods rather triquetrous in 
eross seetion, in age reniform, weakly attached to calyx and sessile or 
stipe half the calyx, abruptly contracted below, very obliquely oblong, 
about 2 em. long, 5-7 mm. wide and high, strongly and closely cross- 
ribbed when fresh with the outer wall fleshy and pulpy and the inner 
woody and the cavity filled with pulp, the septum intruded half way, 
shallow and broadly suleate nearly to tip and base, and canoe-shaped 
dorsally, rounded ventrally and the thick suture raised when dry but 
not when fresh, the deltoid and very short tip about at right angles to 
dorsal suture and declined, seemingly glabrous but minutely pubescent, 
rarely pendent, 1-5. Flowers about 3 and loosely racemose, purple 
tinged, about 1 em. long, broad. Banner nearly 1 cm, long, oblong- 
oval, deeply notched, veined from the back, the midrib purple and with 
a thickened groove on each side running two-thirds the way to tip, re- 
sembling Frasera glands, then the thin sides are reflexed 45° from the 
edge of the groove below but not at tip, arched gently at end of 
ealyx to 45°, dirty-greenish-white with a purple tinge. Wings broadly 
linear, 2 mm. wide, rounded, 8 mm. long and equaling the banner, erose, 
not narrowed above, arched at end of keel to 459, concealing it, about 
flat and close-pressed to it. Keel purple-tipped, sharply rounded 
to about 135°, obtuse, short, straight, 4. mm. shorter than wings, about 
3 mm. high. Calyx 4-angled, the tube about 4 mm, long, barely wider 
above, oblique at base by the lower corner being cut off and so seem- 
ing saccate above, equally inserted, appressed-short-hairy and nigres- 
eent; teeth subulate and about half as long, a little oblique at tip. 
Pedicels 2-4 mm. long, ut least twice as long as the hyaline ovate bracts. 
Peduncles subscapose, 1-2 dm. long, rather stout, ascending 1» erect in 
flower and prostrate in fruit. Leaves 5-10 em, long, very many and 
very narrow, with the stout petiole about one-third the while. Leaf- 
lets about 6 pairs, rather thick 3-5 mm. long, elliptical and obtuse, mostly 
folded and appearing linear, seemingly sharp but mostly obtuse. Stems 
rarely 2-5 cm. long, many from a much branched and woody crown 
from a thick and erect root. Whole plant puberulent, Growing on dry 
rocky ridges, Blue Mts. Oregon and vicinity. Middle Temperate life 
zone and in flower in early spring. 
137. Astragalus obscurus Watson Bot. King 69 (1871). Pods short- 
racemose, shortly-acuminate at both ends, broadly linear, about 2.5 cm. 
long and 3 mm. wide and high, rather triquetrous-reniform in cross 
section, inclined to be a trifle laterally flattened, coriaceous and a little 
fleshy when fresh, not reticulated nor ribbed, both sutures raised ex- 
ternally and the ventral thickened when dry, often reddish but not 
mottled, narrowly and shallow sulcate dorsally, the dorsal suture vari- 
ably intruded from a mere trace to nearly the width of the cavity, 
ashy with close pressed hairs as is the whole plant, sessile on a very 
stout pedicel about 2 mm. long which is about as long as bract, the 
straight tip in line with the dorsal suture not declined. Flowers at 
, first in heads then elongating a little, less than ten, about 8 mm. long. 
Banner oval, about 7 mm. long, abruptly and nearly erect from calyx 
tips, with sides reflexed about 1 mm. wide below only, filled by the very 
broad and large sulcus which is triangular and sharp and 2 mm. deep, 
broader at tip, with conspicuous purple stripes radiating palmately from 
the end of the thick claw. Wings very obliquely obovate, ascending 
45°, close pressed to keel below. with the upper side concave to it and 
flaring and so the blade seems grooved along the middle, very obtuse, 
rounded, shorter than the keel and narrower, about 1.5 mm. wide, 
Keel straight, with tip very sharply rounded to erect and then pro- 
. duced into a straight and sharp or rounded tip, 3 mm. high, dark- 
|. yellow. Calyx a little obeompressed at tip with broad simuses whitish —
