CONTRIBUTIONS TO WESTERN BOTANY. 659 



wavy short hairs, fixed by the base, oval, 4" long, thick, 

 about i5pairs,nearly contiguous, smaller above; peduncles 

 6' long or less, stout, sulcate, capitately 14-20 flowered; 

 not much elongating in fruit; bracts lanceolate hyaline, 

 i-i^/^" long, twice the very short and stout pedicels; 

 flowers spreading, purple, 8" long, large; calyx tube a lit- 

 tle obliquely cylindrical, 4" long, i|" wide, somewhat com- 

 pressed, obliquely attached below and a little narrower, light 

 colored; teeth deltoid to triangular, and a little longer 

 than wide; banner elliptical, blade 4" long, sides reflexed 

 i" wide in the middle, ascending beyond calyx tips to 

 45-60° in gentle curve; wings narrowly oblong, obtuse, 

 arched 45°, i" wide, a trifle longer than the keel and 1" 

 shorter than banner; keel straight, apex gently bent to 

 nearly 90", rounded and obtuse, 3" longer than calyx; 

 pods oval-ovate, 6" long, 4" wide, sessile, glabrous, fleshy, 

 much obcompressed, not sulcate, i-celled, base rounded, 

 apex upcurved, compressed, triangular-acute, 2" long; 

 fruiting peduncles apparently decumbent. 



Astragalus Shockleyi. Perennial, apparently tall 

 and coarse, stems coarsely sulcate, branches zigzag with 

 nodes 2-4' long; stipules very short and wide, very 

 broadly deltoid, adnate, }^" high or less, with a short 

 apiculation, 1-2" wide, with green tip; leaves with thick 

 terete rachis, nearly as thick as the stems, 4-6' long, stiff 

 and ascending, scarcely sulcate, leaflets usually 2 pairs, 

 distant, linear, 6-12" long, thick, often deciduous; plants 

 racemosely branched above, and almost glabrous through- 

 out; the scant leaflets give the plants the appearance of 

 being all stems and peduncles; pods obliquely oblong, 

 about 6" long and 3" wide, round (when fresh) in cross- 

 section, obliquely apiculate and obliquely inserted at base; 

 dorsal suture nearly straight in the middle, but abruptly
