or very nearly so, 2*4" wide, i%" thick, obcompressed, 

 very slightly sulcate ventrally, and broadly so dorsally, 

 but not deeply, 2-celled except at the apex, velvety- 

 pubescent with very short hairs, about one-third longer 

 than the calyx and teeth, barely splitting the calyx tube. 

 Astragalus asckpuido/des Jones. Mr. Sheldon places 

 this species under a new section, " Asclepiadodes" (1. c. 

 9, 159), in his provisional list, completely ignoring the fact 

 that I had previously (Zoe 2," 238) made a section for it 

 and called it " Pachyphyllus ' ' ( Pachyphylla by typo- 

 graphical error). 



No. 5095ah. April 23, 1894, top of grade, four miles 

 above Pagumpa, Arizona, 5000 alt., in gravel, among 

 junipers. 



This plant appears to be identical with A. arktinus 

 when growing, but the 2-celled pod would place it else- 

 where; when dry the greatly compressed, almost vetch- 

 like pod is strikingly different. Stems often single, never 

 many in a place, prostrate or ascending, always ascend- 

 ing in flower; flowers seem to be identical with those of 

 arktinus, but paler; pods linear-oblong, cross section 

 obovate-emarginate, wall fleshy and soft, the pulp %." thick 

 and the pods \%" thick, ventral edge grooved, dorsal 

 edge neither grooved nor ridged externally, but dorsal 

 septum produced nearly to the ventral suture, the septum 

 thin and white, and manifestly double; pod reddish, 

 i%-2* long, arcuate to ^ of a circle, contracted but ob- 

 tuse at both ends; seed cavity small and completely filled 

 by the seeds, which are on stalks 1" long; pods on re- 

 flexed pedicels, but arcuate so that the apex is ascending; 

 stipules very large, blunt and sheathing below, mostly 

 h valine, almost reniform below, ovate above ; bracts ovate, 

 1%" long: pedicels almost none: peduncles 4' long:
