bus var. aberrans Jones. The leaflets vary from 2 to 10 mm. long. 

 Pasco Wash., Mitchell Oregon, and on the John Day and Bruno 

 rivers Oregon. Howell, Cusick, Elmer. Lower and Middle Temper- 

 ate life zones, mostly in more humid places than the type, and less 

 pubescent. 



229. Astragalus Mulfordoe Jones Cont. 8 18 (1898). Onix 

 Rydberg. Pods very thin and 1-1.5 cm. long, 3-4 mm. wide and 

 high, very slightly concave along the ventral suture in the middle 

 only, convex at both ends, often much so, from triangular-acute to 

 bluntly apiculate at both ends, the tip being in line with the dorsal 

 suture, the body half-elliptical to broadly half-oval, 2-5 mm. high 

 in extreme cases, abruptly slender-stipitate and stipe about equaling 

 the calyx tips to 3 times as long, minutely pubescent and finely reticu- 

 lated, shallow sulcate dorsally, opening along both sutures to base, 

 cross-section about deltoid, with concave sides. Flowers about as 

 in A. campestris, short and ai'ched, about 7 mm. long, dii"ty white and 

 purple-tinged, many, in long racemes, ascending to reflexed. Banner 

 waterlined, abruptly arched to erect or more just beyond teeth, 

 deeply and broadly grooved to tip, the groove 1 mm. deep and 2 mm. 

 wide, occupying all of the upper half of the banner, with sides 

 reflexed about V2 mm. wide below and not at all at tip, the ban- 

 ner appears nearly square as you look at it. Wings obliquely ellip- 

 tical, nearly 2 mm. wide in the middle, 2 mm. shorter than banner, 

 the right hand one folded over the end of keel, the other flaring and 

 then both tips touch, both concave to keel and obscurely notched 

 below tip, fully 2 mm. longer than keel and arched, white and 

 waterlined. Keel very short and abruptly rounded to nearly a half 

 circle, very blunt, slightly darker above. Calyx tube rather obliquely 

 inserted at the base, not oblique at tip nor cleit deeper above; teeth 

 triangular and about half as long as tube. Pedicels slender, re- 

 flexed, about 2 mm. long in fruit and longer than the triangular 

 bracts. Peduncles filifoi-m, from 1-7 cm. long, much shorter than 

 the rachis. Flowers loosely racemose and reflexed. Leaves 3-10 cm. 

 long, rigid, with filiform and tapering rachis, not divaricate, narrow, 

 nearly sessile, with 6-12 pairs of linear leaflets gradually reduced to 

 almost nothing at tip of rachis, and distant. Stipules hyaline, with 

 green tips from a cieltoid and filiform base, 3-5 mm. long, recurved. 

 Stems round and green, c^espitose, often a foot long, with slender 

 internodes rarely 5 cm. long, from slender and woody underground 

 branches of the slender and erect and very long root. Growing in 

 deep sand on steep south slopes, Weiser Idaho. Lower edge of the 

 Middle Temperate life zone. 



230. Astragalus Inyoensis Sheldon in Coville Death Valley 

 Rep. 86 (1893). Pods either hall-oval or arcuate-oblong, the body 

 about 1.5 cm. long and 4 mm. wide and high, arcuate, abruptly con- 

 tracted into a linear beak 2-4 mm. long, slightly sulcate dorsally, 

 feften decidedly obcompressed when much arched, on a stout stipe 

 about as long as calyx, nearly smooth, inclined to be coloi-ed. Flow- 

 ers purple, nearly 1 cm. long, wide, straight. Banner abruptly 

 arched at calyx tips to 30°, with sides reflexed 1 mm. wide, 1-2 

 mm. longer than keel. Wings obovate, 1-2 mm. wide, about as long 

 as keel. Keel large and broad, about 4 mm. long and 3 mm. high, 

 half-cuneate-obovaLC, the tip almost square and erect, light-colored 

 toward the base. Calyx tube not oblique, the triangular teeth one- 

 third to one-half as long as tube. Pedicels very short in flower 

 and shorter than the triangular bracts. Peduncles filiform, not ta- 

 pering, about twice as long as the leaves, a little longer than the 

 fruiting rachis, widely spreading. Leaves divaricate, rarely 3 cm. 

 long, wide, the upper nearly sesile, the lower about half the petiole. 

 Leaflets 6-8 pairs, elliptical, about 5 mm. long, rounded, nearly con- 

 tiguous, ashy with closely appressed and short hairs. Stipules rigid, 

 triangular, green, reflexed, 3-4 mm. long. Internodes 1-3 times as 

 long as leaves. Stems very sparsely leafy and elongated, prostrate 

 or widely spreading, with the habit of A. Nuttallianus, several from
