The type is the only specimen of this species known to me. It is a 

 meadow plant, whose affinities are with ^^^1. parvlfolla.

 About ?^ dm. high; leaves broadly spatulate, thin in texture, canes- 

 cent or tomentose, 15-20 mm. long, the cauline about o cm. long; in- 

 volucrul l)racts (pistillate) narrow, the tips white, acutish to acuminate.

This is a doubtful species, as little known as A. foliacea. It appears 

 to be intermediate between that and A. pare! folia. Its leaves resemble 

 thos(^ of the former, Avhilc its heads are more like those of the latter. 

 It is glandvdar alwve, with the ciliate hairs which so often appear in 

 A. parvifolia. The plants in the two cotypes which I \va\q examined 

 are rather immature.

Slender, 1-3 dm. high: stolons short, procumbent; leaves rhomboid- 

 ally spatulate and acute or rarely with the terminal dilated portion 

 obovate and obtuse, 5-15 mm. long, silvery-tomentose on both surfaces 

 or only canescent above; heads in a rounded cluster or in an open 

 cor^mib; involucres 5-6 mm. high; tips of the pistillate bracts usually 

 narrow, obtuse, or acute, dull white or somewhat yellowish; those of 

 the staminate In-acts rotund to oblong, obtuse or truncate, dull white 

 or yellowish white. 



Tyjje locality.— "-On the Black Hills and plains of the upper part of 

 the Platte." Collected by Nuttall; type in the herbarium of the 

 Philadelphia Academy. 



Colorado, Utah, eastern Idaho. Wyoming, Black Hills of South 

 Dakota. Montana, northward in British Aujcrica to Alberta. 



This is distinctively a meadow species, and therefore much later in 

 flowering than the dry ground species of the same locality. It flowers 

 fully a month later than A. aprica of the dry, open plains and slopes
