Pods not over ! em, long. 2-celled, sessile or nearly so, rarely 
a little arcuste, oblique, opening first at tip along both sutures, 
in heads or spikes, small, not inflated, chartaceous, mostly sul- 
cate dorsally, opening but little at maturity, with triquetrous to 
reniform cross-section. Flowers not over 1 cm. long. broad. Ca- 
lyx tube campanulate, rarely 4 mm. long, with subulate or filiform 
teeth about as long as tube, closely sessile, Bracts elongated. 
Very pubescent, tufted plants from woody perennial roots. ` 
KEY 
A. Caespitose plants with very short internodes, conspicuous and hy- 
aline and connate stipules, and leaves 2-3 cm. long Flowers purple, 
in heads on short peduncles. Pods not longer than calyx, very heir. 
128 Austinae 
2A. Plants erect or only decumbent, tufted, with slender stems at 
least a foot high, with slender internodes, open hzbit and narrow 
leaves. Stipules connate only at very base. Leaves 5-10 cm. leng, 
the upper ones sessile or short-petioled. Flowers in spikes, rarely in 
heads, and pods in spikes. 
2AB. Pods not laterally flattened nor longer than calyx. 
Pods not reflexed. 129 Spalcingii 
Pods reflexed. 130 Erauntoni 
2A2B. Pods conspicuously laterally flattened, oblong-lanceolate 
and very sharp, much longer than calyx, 6-10 mm. long. +lowers and 
pods retlexed and in narrow, long, loose spikes. 
131 Ly:llii 
128 Astragalus Austinae Gray Bot. Cal. 1 156 (1876). Pods avout 
7 mm. long and 3 mm. wide, oblong to elliptical, not exserted, shallow 
sulcate, barely splitting the calyx, barely acute, with rounded tip, at 
base notched and short-stipitate, conspicuously l-celled at tip, with 
ventral suture raised and thickened bnt not acute, with dorsal suture 
produced toward but not to the ventral, a little flattened laterally, in- 
clined to be reflexed, with cross-section nearly circular, the groove 
not running tothe tip. Flowers inclined to be reflexed, 7-10 mm. long, 
sessile, 10-12, purple-veined and with light-colored blades, barely 2 
mm. longer than calyx. banner oval-ovate, about 4 mm. lon g, abrupt- 
ly arched at end of calyx to 30-60 degrees, about 3 mm. longer than 
wings, with sides reflexed about 1 mm. wide and most in the middle 
but not at all at tip; groove U-shaped, broad, filling the whole banner 
above. Wings linear to oblong, about 1 mm. longer than keel, a little 
arched, obtuse, the right hand one folded over the keel, the other flar 
ing, both wings and banner hairy on the outside. Keel short, straight, 
2 mm. high, incurved at tip to 110 degrees, purple, barely as long as 
calyx, the tip a knob and very blunt. Calyx narrowly campanulate, 
the tube about 3 mm. long, inserted on the lower corner, cleft deeper, 
above, not narrowed below; teeth green, unequal, arched and lax, fili- 
form, not shorter than the tube. Bracts subulate, 4-7 mm. long, thin. 
- Peduncles 2-7 cm. long, erect, rather stout, mostly longer than the 
=... leaves, subscapose though actually in the upper axils. Leaves clus- 
tered, spreading, the lower long-petioled. Petioles stout, not sulcate,
