above, ending in a short and conical and rather upturned beak, cellu- 
lar-fleshy when yeung, coriaceous when dry, deeply cordate at base, 
fresh pods almost round in cross-section, very cellular and with close- 
ly appressed hairs, young pods thin and rather papery, not woody. 
Ventral suture a little intruded and thin, but both sutures inconspicu- 
ous. Flowers brilliant-dark-purple, fading to bluish, with tips darkest, 
about 2.5 cm. long. Banner oval-ovate, about 1.3 cm long, 3 mm. wide 
and arcuate to about 30 degrees in a gentle arc from. calyx tips, with 
sıdes retlexed a little in the middle, with broad groove forming about 
a half circle and 3 mm. wide and 2 mm. deep then widening and shal- 
lowing to a mere groove at tip, white spot reduced to half a dozen 
white iines low down on each side of the mid-nerve and forming an 
oblong and truncate to obcoidate area. Wings a little darker than 
banner, linear to near the ear, nearly 2 mm. wide and | cm. long aud 
2-4 mm. longer than keel, concave to keel and horizontalattip asin A 
amphioxys, mostly declined, rounded, much narrower than the keel 
and with tips mostly touching and one of them not flaring, sometimes 
there are 2 pairs of wings to a flower. Keel narrow. gently arched 
beyond the middle to 45 degrees or rarely more, witı tip much roun- 
ded, about 2 mm. wide near tip, a little shorter than wings and 4-6 
mm. shorter than banner, straight. Calyx reddish, a little inflated be- 
low and narrowed at tip, barely flattened laterally, the upper sidea 
little arched, nearly truncate below and only a little obliquely inserted, 
about 1 cm long and 3-4 mm. high, white with very fine and rather long 
and loosely appressed hairs, the teeth 2-4 mm. long, subulate and rath- 
erlax. Bracts hyaline, hairy, subulate, 4-6 mm. long, twice as long as 
the stout pedicels. Peduncles hardly as long as the calyx (in the 
type), very stout, even the flowers not exserted beyond the leaves. 
Leaves short, rosulate, many, with petioles often so short as to be al- 
most undiscernible, but generally conspicuous and longer than the ra- 
chis and stout. Leaflets 2-3 pairs, obovate, thick, apiculate, densely 
and closely appressed-hoary-hairy with fine hairs, shortly petiolulate, 
contiguous, 5-10 mm.long. Stipules ovate. Acaulescent plants with 
very thick crowns and closely imbricated stipules, forming very dense 
and small tufts, short-lived perennials from erect roots with few 
crowns. Pubescence soft and fine, rather iong, dense, white, shaggy 
on the pods, with slender and somewhat flattened and warty hairs. 
The above is the type character only. It is.a very variable species, 
the forms being due to shade more than any other ecological factor. 
It (the type) grows only in very open and warm places where the soil 
is inclined to be clayey and poor. Lower Temperate life zone, scarce 
in the southern part of the Navajo Basin, common from Richfield to 
Marysvale Utah on the Sevier and over to Cove Creek and less common 
to Pioche Nevada, Peach Springs Arizona and eastward to the Little 
Colorado. 
Astragalus Purskii X Newberryi. This hybrid has narrowed and 
curved pods, more slender petioles, smaller flowers, and rather loose 
pubescence. This grows on the Sevier. 
Astragalus Purshii X Watsonianus. This has the leaf and pubes- 
cence characters of the var. Watsonianus but the other characters of 
Purshii. This grows in eastern Nevada.

A. eriocarpus Watson. Watson’s type is an over-developed plant 
- growing in the shade of the sagebrush, in which the peduncles and 
leaves were relatively much elongated. The pods are cordate-ovate 
and about 1 cm. long, with lunate-half-oval longitudinal-section and 
_ semicircular cross-section below, then itis abruptly contracted into a 
subconical beak half as long as the body and which is erect and very 
% sharp, the pods are shallow-sulcate ventrally at base and somewhat | 
but not conspicuously inflated as in the type species, and about half its 
size. the pubescence about 2 mm. long and spreading at right angles
