and calyx yellow, the latter with short wool; calyx tube three 

 lines long, two lines wide, teeth a line long and triangular and 

 stout; calyx about as large at base as apex and so short- 

 cylindric; the corolla does not extend more than five lines 

 beyond the calyx teeth; the short very blunt keel whose tip is 

 bent into a semi-circle surpasses the teeth by three lines; the 

 broadly lanceolate wings which are as wide as the keel surpass 

 it by two lines; the broadly ovate banner is sharply arched just 

 beyond the calyx teeth into an erect position and so does not 

 extend as far as the keel; the ovate woolly bracts are hyaline 

 and a line long and equal the stout pedicels; lower part of stem 

 is absent and there is no fruit; stipules triangular, short, green. 

 Collected by G. W. Gibbs on the headwaters of the Carson River, 

 Cal. Read before the Cal. Acad. Nov. 18, 1861. The whole 

 plant has short spreading wool or hairs and is rather canescent; 

 pedicels attached by one corner of the calyx; leaves four inches 

 long; peduncles six inches long, very stout; ilowers six to eight, 

 subcapitate. 



Astragalus cyrtoides Gray, collected by IvCmmon in Sierra Val- 

 ley, Cal., is many stemmed from a woody root, stems often slender, 

 erect and scarcely sulcate, a foot high, flexuous; pubescence even 

 to the calyx the same as in A. Gibbsii; leaflets six to eight 

 pairs, from cuneate and almost lobed at apex to oblanceolate 

 and truncate, six lines or less long; petiole seldom over one-half 

 inch long; leaves three inches long; stipules triangular and like 

 those of ^. G/(5(5i-/z but more acute; peduncles four to six inches 

 long, not very stout, grooved; flowers loosely spicate; pedicels 

 two lines long, twice the length of the ovate, hairy bract, not 

 very stout; calyx narrowed, cylindric-campanulate, four lines 

 long, one to two lines wide, scarcely gibbous at base but pedicel 

 bent at point of insertion to a right angle; teeth the same as 

 those of A. Gibbsii or narrower; flowers the same but wings 

 surpassing the keel only a little; pod an inch long exclusive of 

 the one-half inch long stipe, acuminate at both ends and sharper 

 at base, three lines wide, one and one-half lines thick, cross-section, 

 shallow-obcordate, short-pubescent with erect hairs, one-celled, 

 neither suture impressed, but pod dorsally sulcate, ventral suture
