The two sheets of the American plant found in the Columbia 

 University herbarium differ considerably from European specimens 

 in the same herbarium. The European is evidently a depauperate 

 form of A. dioica or at least nearly related to it. The American 

 plant, besides having a more trailing habit, possesses an almost 

 turbinate involucre, of which only the innermost row of bracts 

 have a broadly oblong obtuse papery appendage ; the outer ones 

 are even destitute of scarious margins. The whole involucre is 

 densely white tomentose. Specimens seen : E. A. Mearns, no. 40, 

 1887, from the Mogollon Mountains, Arizona; E. Palmer, no. 109, 

 1869. 



Antennaria parvifolia Nutt. Trans. Am. Phil. Soc. 7: 406. 



A. dioica var. rosea D. C. Eaton, Bot. King's Exped. 186. 

 Name only. 1871, 



Stems very slender, i ^-3 dm. high ; pubescence of the whole 

 plant fine, silky and somewhat yellowish ; leaves of the stolons 

 narrowly oblanceolate, 2-3 cm. long ; stem leaves linear ; heads 

 small, 5-7 mm. high, in a contracted almost capitate cyme ; bracts 

 of both staminate and pistillate heads in several rows, yellowish, 

 the scarious portion oblong, obtuse, nearly always tinged with 

 rose or pink. 



It is nearest related to A. dioica, differing in the slender habit, 

 small heads, narrow leaves and the color of the plant and bracts ; 

 the staminate plant is very rare. The following specimens are
