ashy when young, nearly smooth when ripe, stiff-papery, flattish, or 
broadly sulcate along the ventral suture, the cross section nearly half- 
' oval. Flowers 7-8 mm: long, few, white or tinged with purple above; 
the banner waterlined or purple-veined, 4-5 mm. long, variously arched 
beyond the calyx tips, about as long as wings. Wings half-obovate, 
acutish, quite oblique, about 2 mm. longer than keel, white, Keel 
half-cuneate with nearly square end and erect tip about 2-3 mm. high, 
à little colored at the end. Calyx turbinate-campanulate, about 2 mm. 
. long, the teeth narrowly triangular and about as long as tube. Leaves 
. rarely 5 cm. long. Leaflets oval to obovate, notched or very 
` obtuse, 28 mm. long, smooth above, ashy below with short and 
closely appressed hairs, the calyx similar but with some black hairs 
.intermixed. Stems quite slender, branching throughout, less than 
a foot long, apparently from underground stems. It has the habit of 
A. Geyeri and appears to be short-lived. John Day valley Oregon.

35. Astragalus pubentissimus T. & G. Fl. 1 693 (1840). A. mu!ti 
caulis Nutt, A. Peabodianus Jones, Phaca Rydberg. Pods ovate to 
lanceolate, 1-2 cm. long, abóut 7-10 mm, wide and 5 mm. high, decidedly 
Obcompressed at base, much laterally flattened toward the deltoid to 
triangular, sharp, apiculate and upturned tip which is 1-5 mm. lorg, 
little if at all mottled, tne cross section from triquetrous-reniform ^^ 
transversely elliptical; jointed to a short stipe, walls very thin and 
wrinkled, hairy within. Flowers either dull purple or tinged with 
purple, ascending when fresh and gradually drooping with age, almost 
capitate or very shortly-racemose, several. Banner oval, abruptly 
arched to erect at calyx tips, the erect part about 4 mm. long, the sides 
much reflexed below, the central part white and purple veined. 
Wings obovate to lanceolate, notched, arched 30-45 degrees, fully 2 
mm. wide, 1-2 mm. longer than keel and 2-4 mm. shorter than hanner, 
Keel 3-4 mm. long, the base nearly straight, and the tip abruptly 
rounded to 110 degrees and deltoid and erect and rather acute, fully 
3 mm. high, deep purple. Calyx tube about 3 mm. long, rather trıın- 
cate at base and attached a little below the middle, cleft deeper above 
with broad sinus and teeth a little unequal, nearly subulate, arched 7^? 
about as long as tube to twice as long. Pedicels about 1 mm, long 
and about as long as the minute triangular bracts. Peduncles 
hardly half as long as the leaves, 1-3 cm. long, the rachis. a little 
shorter. Leaves innumerable (because of the many internodes which 
are rarely 1 cm. long), 2-6 cm. long, broad, the petioles about half the 
whole. Leaflets 3-8 pairs, mostly 5, broadly to narrowly elliptical, thick, 
contiguous, ashy (appearing as if minutely woolly) with partly snresa- 
ing kinked rather appressed hairs, as is the whole plant except the 
shaggy pods. Stipnles rather deltoid, rarely 3 mm. long. Stems rather 
coarse for the plant, round, a few inches to a foot or two long, forming 
mats on the ground. very many and much branched from a slender 
tap root. A short-lived perennial, but blooming the first year. growing 
in clayey or slightly sandy soil on flats from the nnrer Green river 
Basin Wyoming thronghout the Navajo Basin to Farmington New 
Moxico and the San Juan and Henry Mts. Blooming in May and 
June, Lower Témperate life zone. Ed
