ruuo-scierocarpi. 145 



loose racemes. Banner greatly elongated and much longer 

 than the wings and short keel. Wings nearly straight, 



about 3 mm. longer than keel, 2 mm. wide. Keel about 5 mm. 

 long, abruptly arched to 90 degrees at the very obtuse tip 

 which is as high as the base is long. Calyx tube< oblong, about 

 7 mm. long, 3 mm. high and 1.5 mm. wide, the teeth about 

 half to a third as long. Leaflets 1-3 pairs, all but the lowest 

 sharp and linear, flat, often falcate, inclined to taper above, 

 very distant. 



Leaflets linear. io6 Serenoi. 



Leaflets lanceolate or broader. 107 canonis. 



2A2B. Pods with thick and jointless stipe which is fully as 

 long as calyx, the pod narrowly oblong, short-pointed, arcuate, 

 and with the stout and arched stipe forming a third of a circle, 

 not completely 2-celled because the two sutures though touch- 

 ing do not unite, much laterally flattened when dry and with 

 the partition splitting double and the pod opening at tip at 

 at both sutures for a short distance only and the dorsal open- 

 ing to the base and into the stipe but not through it nor the 

 partition. Flowers shortly racemose and rather few, nearly 

 horizontal, white. Calyx tube rnmpanulate, abruptly con- 



tracted below, with the upper side arched and the lower 

 straight, reflexed in fruit but the pod erect, with teeth as long 

 as tube. Leaves about 1 dm. long, with slender rachis and 

 somewhat tapering, and with many obtuse and mostly folded 

 leaflets about 1-2-5 cm. long. Stems hoary, rather weakly 

 ascending and little branched, shrubby below, 2-4 ft. long. 



Pods narrow, on a very thick stipe. 108 pachypus. 



97. Astragalus Toanus Jonps Zoe 3 296 (1893). Pods acumin- 

 ate, lanceolate to oblonglanceolate, appressed and erect, mostly de- 

 cidedly laterally flattened, in short racemes at the tip of peduncle 

 which is strict. The sutures evident but not very thick uniting in 

 a pungent and triangular beak, body slightly cross-ribbed, with the ven- 

 tral suture about straight, the dmsal arched. Texture coriaceous 

 when dry but with the walls much thinner than in other Podo-sclero- 

 cprpi. About 1.5-2c-<v. Inner, and 4-.5 mm. high, and 2-o mm. wide when 

 dry. When fresh the walb about 2 mm. thick, with thin outer skin 

 and soft fleshy substance up to the woody inner wall. Banner oblong 

 and notched, with white spot nearly square and coming within 4 

 mm. of tin, with sides reflexed a little at base, the blade 1.25 cm. 

 long, gently arched from calyx to 45 degrees, veined. Wings barely 

 arched, linear, concave to keel and flaring beyond, white beyond 

 the keel, rounded, nenrly 5 mm. longer than keel. Keel about 1 

 ram. long, 2 mm. wide at base and 3 mm. at tip, the base straight 

 to tin where it is arched in very short arc to erect, the tip very 

 broadly deltoid. Calyx long-campanulate, nearly 5 mm. long and 3 

 mm. wide, base straight, upper side arched, oblique at both ends, cleft 

 deeper above, laetrally flattened, teeth deltoid and 1 mm. long, tube 

 reddish and ashy. The flowers are about the color of A. Utahensis, 

 pinkish-purple except for the white wings, ascending. The pods are 

 very variable in relative length and acuteness as well as amount of 

 compression. Plants ashy when young, densely tufted in a round 

 clump with innumerable slender, sulcate stems erect, not flexuous, 

 about 2 ft. high, with a strong smell of cabbage when bruised. Ped- 

 icels stout and ascending. Peduncles at least 1 dm. long. Leaves 

 5-8 cm. long and narrow. Stipules reflexed above, with nearly subu- 

 late tip. Internodes often 1 dm long. Leaflets rudimentary to 2 

 cm. long, channeled. On the high plains of central Nevada from 

 Contact and Ferguson Springs Nevada to Burbank Utah near Jeff
