lectors since from various localities in the mountains of San Bernard- 

 ino and San Diego Counties. 



Astragalus conjunctus. Perennial, with very short stems, 

 very sparingly appressed-pubescent : leaflets 5 to 10 pairs on an elon- 

 gated rhachis, linear, 4 to 6 lines long: peduncles elongated (6 to 12 

 inches high), bearing an open few-flowered raceme; pedicels very 

 short: calyx narrowly tubular, 3 or 4 lines long, dark-pubescent, with 

 short narrow teeth; petals pale purple, 6 to 8 lines long: pod coria- 

 ceous and rugose, erect, sessile, narrowly oblong and nearly straight, 

 acuminate, 1-celled with the dorsal suture impressed, 9 to 12 lines 

 long. — In John Day Valley, Oregon (J. Howell, in May, 1880), and 

 on sterile rocky ridges in Baker County, by W. C. Cusick, 1881. 



Lathyrus Cusickii. Glabrous or sparingly pubescent, slender, 

 from a slender perennial rootstock, h to 2 feet high, without tendrils : 

 stipules narrowly semisagittate ; leaflets 2 or 3 pairs, linear-lanceolate 

 to narrowly linear, acute or acutish and mucronate, 2 or 3 inches long : 

 peduncles equalling or exceeding the leaves, 2-3- (rarely 5-) flowered : 

 corolla white, 10 to 12 lines long; the calyx 3 or 4 lines long, with 

 nearly equal teeth, pod attenuate to a narrow base, l^ to 2 inches 

 long by 3 lines broad : hilum short. — On dry mountain slopes, Union 

 County, Oregon ; W. C. Cusick. Resembling narrow long-leaved 

 forms of L. palustris, but with much larger white flowers, the tendrils 

 wholly wanting, and the hilum of the seed much shorter. 



Desmanthus obtusus. Decumbent, finely pubescent: pinnae 

 usually two pairs, upon a very short rhachis (rarely h inch long) ; 

 leaflets oblong, veined : head small and few-flowered, on peduncles 

 much exceeding the leaves (1 to 2}, inches long) : pods narrowly linear 

 (8 to 16 lines long), straight, obtuse or slightly narrowed at base, ob- 

 tuse and apiculate at the apex, — Western Texas ; Dr. V. Havard, 

 August, 1881. Allied to D. reiicidaius, Benth. ; see page 349. 



IvESiA Utahensis. Alpine, the short caudex densely covered 

 with the remains of dead leaves, viscid-pubescent but the pubescence 

 less glandular above, the prostrate stems |- to 1| feet long: leaves 

 mostly radical, about 2 inches long, with numerous approximate 3-5- 

 parted leaflets, the segments oblong-oblanceolate, obtuse, 1 or 2 lines 

 long ; cauline leaves few, short and with few nearly entire leaflets ; 

 stipules large, ovate: inflorescence somewhat dense: calyx 1^ to 2 

 lines long, the teeth equalling or exceeding the tube, and the accessory 

 lobes narrow ; petals white or pinkish, narrowly spatulate, slightly 

 exceeding the sepals : stamens 10 : pistils 1 to 3, on a very villous 

 receptacle. — On the summit of Bald Mountain in the "Wahsatch
