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, 1S91, and connecting forms at Cisco 

 at the same date. 



Astragalus Preussii Gray var. SULCATUS, n. 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 ver}' 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 Kastwood, at Cane Spring, Utah, May, 1892. 

 This is so like the variety latus, except in the sulcate pod, that 

 it seems best to put it as a variety of the above. 

 ^ Astragalus pidns 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 

 Kastwood 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 pai^ans. Stems long and flexuous ascending or 

 erei^t from a perennial root, nodes distant, glabrous throughout
