and the flowers much elongated and often nearly yellow. This is 
the common form throughout the Navajo Basin far up on the Little 
Colorado eastward into its New Mexican and Colorado borders and 
down the Colorado to the edge of Nevada and up.the Virgin in

Astragalus confertiflorus var. flaviflorus (Kuntze).  Traga- 
cantha flaviflora Kuntze Rev. Gen. 2 941 (1892). A. flavus Nuttall, 
Cnemidophacos Rydberg. This has the leaves of the species but 
inclined to have narrowly oblong and flat leaflets, the lowest very 
short and broad. Upper leaves much the best developed. Pods 7-12 
mm. long, generally twice the calyx, ovate to oblong oval, variably 
pubescent with curved hairs, about straight, retuse at base, minutely 
stipitate, broadly and rather deeply suleate dorsally and the su- 
tures nearly touching. Flowers 12-15 mm. long, in the type cream 
colored and with rather short and mostly ovate banner, but var- 
iable. Wings linear, narrower than keel, a little arched, 2-3 mm. 
longer than keel.  Keel a little arched along the claw, the blade 
abruptly incurved at the end to erect and very obtuse, the upper 
corner being about square or very rounded and not at all pro- 
duced, the general outline being oblanceolate, straight. Calyx short- 
cylindric, the tube nearly 5 mm. long. Peduncles 1.5-3 dm. long, 
strict, stout and sulcate, appearing as if subscapiform. Spikes loose, 
1-1.5 dm. long, 10-15-flowered. Leaflets broadly linear to narrowly 
elliptical, rather acute, nearly smooth above. Stems short and 
with short internodes, diffusely branched and decumbent, 1.5-2 dm. 
long. Deserts of southern Wyoming, Lower Temperate life zone.

narrower than the- keel. Keel short, about as long as calyx tips, 
straight, with tip abruptly erect and deltoid. : Calyx tube short- 
campanulate, not 5 mm..long, white with very long and appressed 
hairs which toward the tip and on the lobes are widely spreading and 
shaggy. Hairs flat, twisted, with pustulate base, attached by the 
end. Calyx. lobes subulate from a broad base, 9 mm. long, lax, 
green, longer than the tube. Bracts large, 9 mm. long, green, lin- 
ear-subulate, about equaling the calyx. Spikes very dense, 2.5-7 
cm. long. Peduncles 5-15 cm. long, slender, subscapiform, as long 
as leaves. Stipules connate nearly to tip, green (hyaline below). 
long-acuminate, densely. appressed-villous as well as stems. Pet-

tose, ascending, rather stout for the plant, short, flexuous, 2.5-20 
em. long, biennial or short-lived perennial, whole plant 1.5-3 dm.
