var.jmrpurcnm, Gray, Proc. Am. Acad. xix. 72 (1883) : Syn. 

 Fl. 43a. 



Sparsely laiiate (under the involucre densely so) when 

 young, in age glabrate, glaucous : leaves from linear to lance- 

 olate, saliently or often runcinately toothed or lobed : outer 

 bracts of the involucre short, oblong, obtuse, commonly dark 

 brown at the tip : expanded head 1 inch wide, deep satrron- 

 color (purple in the dry): achenes | to 2 inch long, the very 

 slender beak as long as the body. 



Common among the foothills of the Rocky Mountains in 

 Colorado and New Mexico, either on open dry hillsides where 

 it IS low and depressed, or in long borders of meadows where 

 it is erect and often two feet high. It is less related to the 

 foregoing than to the next.

otouter than the last; leaves broader and less apt to be

A species of the very widest range geographically, and 

 undergoing corresponding diversities of size ; nevertheless, 

 ^ extended by the author of the Synoptical Flora, probably 

 embracing several species; for some of the plants placed 

 ^lo"g ^nth it in the herbaria seem not to be glaucous, while 

 others have peculiar pubescence ; but the mass of collectors 

 '^ave practised the child's play of collecting flowering speci- 

 i«ens and leaving the all-important fruits behind ; so that no 

 satisfactory discrimination of species or varieties can yet be 

 made. KuttulFs T. rosenm, belonging to the elevated plains
