and calyx yellow, the latter with short wool; calyx tube three 
lines long, two lines wide, teeth aline 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; flowers six to eight, 
subcapitate. 
Astragalus cyrtoides Gray, collected by Lemmon 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. Gibdsii; 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 A. Gibbsii 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
