41. Astragalus metanus Jones Cont 7 666, 733 (1895) . Pods 

 decidedly laterally compressed, lenticular, much the shape of the 

 montanus group, obliquely ovate-elliptical, upper one third vetchlike, 

 lower part swelled out by the few seeds, minutely piiberulent, 10 mm. 

 long, 5 mm. high, tip deltoid to triangalar-acate, ventral suture ne:^.rly 

 straight, narrowed at very base, cress section oval near the base. 

 Flowers racemose, nearly sessile, purple at tip, horizontal, aboat 7 ;nm. 

 apart. Banner 7 mm. long, bent abruptly 2 mm. beyond the calyx 

 teeth to 45 to 90 degrees, oval, sides reflexed 1 mm. wide, most at 

 base. Wings arched 30 to 60 degrees exposing the keel, oblong to 

 oblong-lanceolate, 2 mm. shorter than the banner, narrower than the 

 keel. Keel abruptly bent at tip to 110 degrees, about 1 mm. shorter 

 than the wings, produced to a point, 3 mm. high, light-colored, with 

 base a little arched. Calyx broadly campanulate; tube 2 mm. long, 

 scarcely oblique at mouth; teeth triangular, about a third to half as 

 long as tube. Pedicels not slender, 1 mm. long. Peduncles including 

 rachis about a foot long, sulcate, normally 3-4 times as long as the 

 leaves, often 5 dm. long. Leaves 10-15 cm. long with proper petiole 

 2 3 oai. long on the lower leaves and absent on the upper ones. 

 Leaflets linear lanceolate, barely acute, not contiguous, 3-4 cm. long, 

 thin. Internodes 7-10 cm. long. Stipules very small, green, 2 mm. 

 long, reflexed, adnate, not connate. Stems prostrate from perennial 

 rocts, 2-3 ft. long, rather stout, sulcate. Plants minutely pubescent 

 throughout with fine and appressed hairs fixed by the base. Hansen's 

 ranch, Lower California near the boundary. Orcutt. 



42. Astragalus Vaseyi Watson Proc. Am. Acad. 17 370 (1882). 

 Pods obliquely ovate, often a little obcompressed below, flattened 

 only at very tip which is short and deltoid, about 1 cm. wide, spicate, 

 all on one side of the floral rachis as if pendent on ascending stems, 

 2 cm. long, usually with a little boss at base, when inmature then 

 often somewhat laterally compressed. Flowers spicate, the same as 

 in A. metanus except that the calyx is campanulate and teeth as long 

 as the tube. Peduncles with floral rachis rarely over twice as long as 

 the leaves, not over 1.2 dm. long. Leaves rarely over 1 dm. long. 

 Leaflets elliptical to narrowly so, flat, apiculate, rarely over 2 cm. long. 

 Internodes seldom over 2-3 cm. long. Plants slender, flexuous, (said to 

 be) shrubby at base, silvery throughout with closely appressed hairs 

 except the minutely puberulent pods. On the California desert south 

 of the Mojave river and east of the Sierras. Tropical. 



43. Astragalus Thurberi Gray PI. Thurber 312 (1855). Pods only 

 minutely pubescent, about 6-8 mm. long, papery, faintly sulcate dorsally, 

 nervose, rounded at base, widely spreading, with both sutures evi- 

 dent, jointed to a minute stipe. Flowers 4-7 mm. long, purplish to 

 och roleucous, many. Calyx tube campanulate, not gibbous, about 2 

 mm. long, teeth subulate and about as long as the tube. Bracts subu- 

 late, 2 mm. long longer than the pedicels, leaves many, rather appres- 

 sed. Petioles one third to one half the whole. Leaflets 5-7 pairs, 2-10 

 mm. long, rather distant or Crowded, narrowly oblong, obtuse, fleshy, 

 retuse. Stipules triangular, adnate. Stems many spreading, rather 

 stout, about a foot long, with short internodes, wih many appressed 

 branches below, rather rigid, leafy, apparently winter annual. Plants
