Hills, near the copper mines, New Mexico ; Oct. (1139.) — Stems 3 or 4 feet 

 high, paniculately much branched, smooth ; the branches, &c. very minutely gland- 

 ular-scabrous. Leaves from the base of the stem not seen ; the upper cauline all 

 alternate, l^ to 2 inches long, and the petioles i to | inch long ; those of the flower- 

 ing branchcs similar but smaller, not numerous. The leaves are rimd, but not so 



30US as those of B. baccharidea, not much reticulated. The very numerous 

 are larger than in the last-namcd species (about 5 lines long), and the inflo- 

 rescence more open. Pedicels IJ- to 3 lines long. The scales of the involucre are 

 nearly all tinged with purple, especially above the middle. In the arrangement of 

 the species published in VI Wnyht p. 84-86, this would stand between B. bac- 

 charidea and B. reniformis. It is probable that its lower leaves are cordate.
