2/6 Contributions to Western Botany. [zoe 



seed-bearing, sessile, rounded at base, early splitting the calyx, 

 cross section apparently broadly obovate, tip with a very 

 pronounced flat and sharp, triangular beak, two lines long; dorsal 

 suture very convex, ventral slightly so; seed stalk one-half a 

 line long. Flowers and pods horizontal or nearly so. The spike 

 of flowers reminds one of those of Oxytropis deflexa. 



Astragalus inversus^ n. sp. Allied to A. stenophyllus and colli- 

 mis. Susanville, California, July i, 1892, Brandegee. Glabrous 

 throughout. Stems flexuose two feet long, straggling upward, 

 small, apparently simple, faintly angled, floriferous above the 

 middle, nodes two to three inches apart; stipules, lower ones, 

 rather small and united at base, the rest green and tapering to a 

 long point and reflexed, four lines long, distinct; peduncles ten 

 inches long, as stout as the stems, at least twice as long as the 

 almost filiform petiole and leaflets; leaflets an inch long, distant, 

 about three pairs, all jointed to the petiole; flowers loosely 

 racemose on the upper half of the peduncle, six to ten, distant 

 in fruit, ochroleucous; keel very gently arched at tip and blunt, 

 narrow, rather long-clawed, six lines long, nearly equaling the 

 narrow obtuse wings and small banner, the latter ascending only; 

 calyx teeth very short-triangular, one-quarter the length of the 

 campanulate tube which is one and one-half lines long and 

 narrowed at base, not oblique, apparently equally toothed, dark 

 and finely pubescent; pedicels a line or less long; bracts minute, 

 ovate; flowers ascending, in fruit reflexed but not pendulous; 

 pod long acuminate at each end, compressed, one and one-half 

 inches long, two lines wide, linear, cross section elliptical or 

 narrower, one-celled, sutures not prominent nor at all impressed, 

 dorsal suture concave and ventral convex and so the pod seem- 

 ing wrong side up; stipe not jointed, nearly an inch long about 

 lialf as long as the pod; seeds nearly round, manj-. The pod is 

 purple and streaked with white, cartilaginous. 



Astragalus collinus Dougl. var. Calif orniais Gray. To this I 

 refer with some hesitation a plant collected at Ager, Siskiyou 

 County, California, July, 1887, by Brandegee. Glabrous, cartilag- 

 inous, reticulated pods two inches long, two lines wide, and stipe 

 three-quarters of an inch long, cross section oval, seeds a line
