coriaceous. Plant a foot high, or less, and growing in dense 
clumps. This is seemingly very distinct, but is connected with 
the type by forms with ovate pods. In pubescence, pedicels, 
calyx, and corolla it agrees with the type. Collected by me at 
Green River, Utah, May 7, 1891, and connecting forms at Cisco 
at the same date. 
Astragalus Preussit Gray var. SULCATUS, Nn. var. Densely 
branched from the base which is almost woody, six inches high. 
Stipules not large lower ones sheathing, hyaline, very broad and 
blunt. Leaflets about ten pairs as in the type, but generally 
narrowly oblanceolate, two to four lines long, rachis two to four 
inches long, and proper petiole very short. Flowers a line 
shorter than type on pedicels two lines long, which are twice the 
length of bract. Calyx three lines long, cleft a little deeper than 
the type and not contracted at throat, otherwise both calyx and 
corolla as in the type. Pods horizontal, oblong-oval, abruptly 
contracted at both ends, apex very acute with a short triangular 
beak, pod round in cross-section, straight, ventrally sulcate a 
line deep and suture often extended one-fourth of a line deeper, 
pod much inflated, chartaceous, three-fourths of an inch long, 
often reddish, but not spotted. Collected by me in abundant 
specimens May 6, 1891, at Westwater, Colo., and in fruit only 
by Miss Alice Eastwood, at Cane Spring, Utah, May, 1892. 
This is so like the variety /a/us, except in the sulcate pod, that 
it seems best to put it as a variety of the above. 
Astragalus pictus Gray var. ANGUSTUS, n. var. Like the type 
but pods eight lines long, two to three lines wide, oblong- 
oblanceolate very acute at apex and narrowed gradually into the 
stipe which is as long as the calyx. Collected in Montezuma 
Cafion, Utah, May, 1892, by Miss Alice Eastwood. 
Astragalus desperatus Jones. Specimens collected by Miss 
Eastwood have the over-ripe pods almost chartaceous. 
Astragalus Coltoni Jones has the pod in one specimen 
broader and less stipitate, and in another specimen has the 
leaves much broader, otherwise as in the type. 
ASTRAGALUS PALANS. Stems long and flexuous ascending or 
erect from a perennial root, nodes distant, glabrous throughout
