Astragalus terminalis. Perennial, canescent with a fine white 

 appressed pubescence, the slender stems 6 to 10 inches long: leaves 

 long-petiolate, with broad triangular stipules ; leaflets 6 to 8 pairs, 

 linear-oblong to oblong-obovate, obtuse, 3 to 5 lines long: raceme an 

 inch long, open, long-pedunculate : flowers nearly sessile, reflexed", 

 purplish, 5 lines long: calyx campanulate, the teeth very short and 

 broad ; keel with a very short blunt purple beak : pod coriaceous, ses- 

 sile, straight, erect, narrowly oblong and turgid, G lines long, narrowly 

 channelled on the back and nearly 2-celled, the ventral suture promi- 

 nent. — Southern Montana, on the gravelly bank of Red Rock Creek, 

 in July, 1880, near the then terminus of the Utah and Northern Rail- 

 road ; S. Watson. Nearly allied to A. adsurgens. 



Astragalus giganteus. Perennial, the stout erect stems 2 to 3 

 feet high or more, tomentose : leaves villous-pubescent and subtomen- 

 tose ; leaflets 5 to 10 pairs, oblong-ovate, acute, 6 to 9 lines long, less 

 pubescent above ; stipules broad : racemes short and rather few- 

 flowered, erect, pedunculate: pods 2-celled, coriaceous, ovate, acumi- 

 nate, somewhat compressed and the ventral suture impressed, sessile, 

 erect, 9 lines long. — At Fort Davis, Western Texas ; Dr. V. Havard, 

 1881. Flowers unknown. A striking species, which seems to have 

 escaped all previous collectors. 



Astragalus grandiflorus. Dwarf, densely cespitose and 

 scarcely caulescent, covered throughout with a subappressed villous 

 pubescence : leaflets 7 or 9, oblong-obovate to nearly orbicular, 2 to 5 

 lines long: peduncles shorter than the leaves (1 to l^- inches long), 

 few-flowered : calyx cylindrical, about 9 lines, the narrow teeth 2 

 or 3 lines long; petals purplish-red, 16 to 18 lines long, the claws 

 exserted, and the keel nearly straight and erect : ovary densely white- 

 silky, sessile, narrowly oblong, 1-celled. — In the San Bernardino 

 Mountains, toward the Mohave Desert, at 5,000 feet altitude ; S. B. & 

 W. F. Parish, May, 1882. Evidently belonging to the group of 

 Eriocarpi, with unusually large reddish flowers. 



Astragalus Vaseyi. Near A. Homii and A. crotaJarice, appar- 

 ently biennial, canescent with appressed silky pubescence, a foot high 

 or less: leaflets 7 to 10 pairs, obtuse or acutish, mucronate, 3 to 8 

 lines long : peduncles exceeding the leaves ; raceme rather loose : 

 calyx-teeth acuminate-deltoid, little shorter than the campanulate tube ; 

 petals purple or purplish, 4 lines long : ovary silky ; pod membranous, 

 ovate-oblong with a straight ventral suture, sessile, usually reflexed, 

 finely pubescent, about 9 lines long. — At Mountain Springs, San 

 Diego County, California, by G. R. Vasey, 1880, and by several col-
