intruded; seeds large, fully a line long and nearly round, on a 

 stalk a line long, few, confined to the middle of the pod; calyx 

 one and one-half lines long, campanulate, scarcely oblique at 

 narrowed base; subulate teeth one-half shorter. The cross 

 section of the pod is probably round. 



Specimens collected by Mr. Lemmon in Sierra County have 

 long underground stems and short ascending stalks, four inches 

 high, decumbent; pods thicker, one-half as large, more attenuate, 

 with the stipe only equaling the calyx; leaves ovate to elliptical, 

 acute, with prominent midnerve and very hairy. This would 

 seem to connect with A. Whitney i. The pods of both these 

 species are one-celled. The flowers are not found in these 

 specimens, but are said to be white in the former and purple in 

 A. Whitney i. 



Astragalus provif erics xs.. sp. San Pedro Martir, Lower Califor- 

 nia, May 5, 1893, Brandegee. Allied to A. Hor7iii. Shrubby at 

 base, one to two feet high, stems ascending, whole plant hoary with 

 very short woolly pubescence which is denser above; the flowers 

 only are glabrous, not the calyx; leaves four inches long, 

 with a petiole an inch or less long; leaflets about ten pairs, 

 oblong-lanceolate and obtuse but apiculate, to obovate and 

 obtuse and not apiculate, three to ten lines long and one to three 

 wide, acute at base; stipules triangular, herbaceous, acute, two 

 to three lines long, upper ones little reduced; peduncles stout, 

 one-half as thick as stem, six inches long, erect, many flowered 

 from below the middle, racemose in fruit and spicate in flower; 

 flowers dark purple, but keel lighter, fading to ochroleucous; 

 calyx broadly campanulate, tube a line long, oblique, cleft 

 deeper above; pedicels almost obsolete shorter than the obscure 

 ovate bract, teeth as long as the tube, subulate, erect; keel three 

 lines long, bent abruptly to a right angle or more at tip, acute, 

 arched a trifle; wings lanceolate and apparently notched at 

 tip; banner rather large, nearly round, ascending 80° abruptly 

 from a point beyond the calyx teeth, a line longer than 

 wings and keel, emarginate; pods obliquely ovate to oval, six 

 lines long, three to four wide, chartaceous, inflated, one-celled, 

 neither suture in the least inflexed, dorsal suture not evident, 

 ventral suture much thickened in the middle where only, it is
