into a stipe which is jointed and then produced as a stipe which is 
about as long as calyx, the whole stipe as long as or twice as long 
as calyx tube. Flowers in the type cream-colored almost exactly as 
as in A. Beckwithii, shortly racemose, about 10, ascending, about 1.5 
cm. long, rather wide. Banner oval to broadly oblong, arched abrupt- 
ly to 45 to 90 degrees, remote from calyx tips, nearly 1 cm. long, with 
sides reflexed in the middle and so appearing fiddle-shaped, the erect 
part a little humped near the middle by the half-conical sulcus. Wings 
2-3 mm. shorter than banner and nearly as much longer than keel, 
about 2 mm. wide and linear. Keel with exserted claw, about 3 mm. 
long and high, very obtuse and arched to a half circle, barely darker 
tipped. Calyx tube campanulate, about 4 mm. long and high, nearly 
equally inserted at the rounded and slightly oblique and fleshy base, 
cleft a little deeper above with ʻa broad sinus but hardly oblique, 
all the sinuses rounded, and teeth filiform and as long as tube. 
Pedicels 3-4 mm; long, nearly as long as the lanceolate and hyaline 
bracts. Leaves about 1 dm. long, narrow and rather rigid, with pet- 
iole decidedly shorter than the rachis. Leaflets 4-12 pairs, from round 
to oblong-elliptical, always with cuneate base, 1-2 cm. long, smooth 
and leathery, glaucous. Stipules triangular-falcate, rather rigid and 
spreading, not over 5 mm. long. Stems slender, in tufts, rarely a 
foot long, flexuous, with congested lower nodes, leafy, the upper in-. 
ternodes rarely 3 em. long, ascending or the central ones erect, from 
an erect, slender, fleshy root, Common on gravelly slopes in desert 
regions from Gunnison Colorado to the Sierras, northward through 
Utah Valley Utah and the Reese river Nevada, southward to the 
Mogollon plateau Arizona and the Charleston Mts. and Death Valley. 
Lower Temperate life zone. This and A. Beckwithii inhabit the same 
regions but do not grow together nor seem to hybridize, The south- 
ern forms are mostly the var. artipes. Bailey's specimen mentioned 
in Coville's Death Valley Rep. is A. megacarpus. : 
Astragalus oophorus var. caulescens (Jones Cont. 7 643 (1895) 
(1878) as species). This has purple banner and keel and white wings, . 
calyx teeth triangular and about half as long as tube, tube often 
7 mm. long and 4 mm. high, pods inclined to be acuminate into the 
stipe, papery and much mottled. This is the common form of the 
southern range. o 
Astragalus oophorus var. caulescens (Jnes Cont. 7 643 (1895) as 
mezacarpus var. This is a form with nearly coriaceous pods acu-

3 (1855). Pods oblong and obliquely acuminate, 2.5-4 cm. long, 7-10 
mm. wide, cross section Y-sbaped by being bisuleate ventrally and the 
suture raised as a sharp and strong rib, concavely triquetrous mostly, 
rather reniform in the var. Weiserensis, a little fleshy when. fresh,. 
transversely rugulose or smoothish, dorsal side a little convex or flat 
or a trifle sulcate, in the type not pulpy within when fresh, often 
minutely and sparsely black-hairy, with stipe about as long as calyx 
and then jointed to the tapering and stipe-like base of pod. Flowers 
crowded in short racemes, cream-colored in the type, about 1.5- em. . 
long, 6-10. Banner abruptly arched about 4 mm. beyond calyx tips 
and opposite the end of keel to erect, oblong, deeply notched, with 
sides reflexed only in the middle, and fiddle-shaped, waterlined; groove _ 
broadly V-shaped above, a half circle below and making the lower . 
part of banner very convex externally and club-shaped above the /
