 plain.s, aud other open grouuds, from Illinois and W. Alabama north to Saskatchewan, south 

 to Arizona, and west to British Columbia and the coast of California; in various forms. 

 The typical eastern and northern plant is rather large, with cinereous and rougliish but not 

 canescent pubescence. Westward, e.xtending to the southern part of California, it usually 

 becomes more canescent and villous as well as hirsute and liispid; the size and fnhiess 

 of the heads greatly varying. The more marked but quite unlimited forms are the fol- 

 lowiug : —

 viscidulous. — Utah and ^Vrizona, in the mountains, Jones, Greene, Pringle, L-uiuiun.

■ Var. canescens. Wholly canescent with short and appressed sericeous pubescence, 



and with some spreading hispid bristles along the stem aud margins of the narrow mostly 

 oblanceolate leaves : heads small : involucre also canescent : outer pappus less distinct. —

 one with slightly canescent leaves, Colorado, Greene. 



Var. sessiliflora. From hirsute and hispid or greenish to viUous-canescent : leases 



oblong or spatulate : heads mostly large, solitary and foliose-bracteate at base : outer pappus 

 more conspicuous and sijuamellate. — V. {Phyllotheca] sessiliflora, Xutt. Trans. \vl\. Phil. Sue.
