VOL. II] Utah Plants. 243 
gular, rather large, connate only at base; peduncles 3 inches long, 
slender, spreading at right angles to the stem, or nearly so; flowers 
subcapitate, 10 to 15, sessile, light yellow, small, less than 4 lines 
long; calyx 2 lines long, campanulate, equaling the subulate lobes 
which come within 2 lines of the length of the flowers; flowers with 
keel nearly straight and dark tipped; banner and wings but little 
longer than keel; pods not reflexed, sessile, purple-spotted, short- 
pubescent, apiculate, oval, 8 lines long, inflated, chartaceous, cross- 
section nearly round, dorsal suture inflexed nearly a line deep, 
ventral scarcely any, neither suture thickened, pod 1-celled, straight, 
generally only one or two maturing on a peduncle. 
This plant has the habit of A. humistratus, and is very readily 
mistaken for it. The pods resemble those of A. filifolius, var. 
pictus. It belongs near to the Lotiflort?. Collected by me on June 
23, 1890, in Sink Valley, southern Utah, at about 7,000 feet alti- 
tude, among the underbrush along the road. I take pleasure in 
dedicating it to my friend, A. L. Siler, who has labored under the 
greatest difficulties in collecting the flora of that inhospitable region, 
and who, though he has never seen this plant, has collected many 
rare and some new species, and has never had due recognition. 
ASTRAGALUS DESPERATUS. Czspitose from a woody root, 
strigose-pubescent throughout; stipules large, free, ovate to orbi- 
cular, scarious, densely imbricated on the very short stems which 
afterwards elongate somewhat, leaves 2 to 4 inches long, petioles 
about an inch long, earliest leaves generally small’ and leaflets 1 to 
4 lines long, oval to orbicular, later leaflets from obovate and obtuse 
to narrowly lanceolate and very acute at both ends, seldom exceed- 
ing 6 lines long, often much less, about 7 pairs; peduncles exceed- 
ing the leaves, oceasionally 6 inches long, scapose, many flowered; 
flowers subcapitate at first, later they are racemose, nearly sessile 
(pedicel much shorter than the ovate bract which is 2 lines long), 
soon reflexed, purple, 6 lines long; wings slightly exceeding the 
very blunt, straight keel; banner broad, a line longer than the keel, 
deep-purple as well as the keel and wings, erect, conspicuously 
veined at the top; pod sessile, reflexed, thin-chartaceous, falcate, 
acute, about 6 lines long, triangular in cross-section, base cordate 
by the intrusion of the ventral suture, 4 lines broad, long-hairy. 
Allied to the 2zfla#z. The flowers and general appearance suggest 
forcibly Oxytropis Lambertt.
