cles, less floccose and less sagittate leaves.

` CERNUA var. nov. Differs from the type in its less broad, cer- 
nuous heads, the purple involucral scales broader, with more 
rounded and more mucronate apex, the midrib less spinescent. 
This puzzling form presents some characters strikingly differ- 
ent from those of the type, but I cannot establish specific distinc- 
tions. It varies from 1 dm. in height, with solitary heads and 
basal leaves 8 cm. in length, to 7 dm. in height or more with 
basal leaves more than 3 dm. in length and 5 to 8 racemosely 
arranged heads. The leaves are oblanceolate, more or less 
coarsely sinuately and rather deeply and pungently toothed. 
The heads are cernuous, 2 cm. long, as broad or broader, with 
broad, mostly deep purple involucral scales, and a deeply tawny 
pappus. 
Near snow-line, Mt. Tunari, 1891 (1049). The larger form of 
it from Espirito Santo, 1891 (1218)
