in less than 3 series, the tips of the pistillate usually from oval in the ^

 lanceolate in the outer to linear in the inner and acute or acuminate, 

 in color from greenish brown to yellowish white, rarely rose color,

A dry ground species, occurring on high hills and occasionally on 

 open plains at subalpine elevations. It is characterized by its short, ; 

 very plain, obtusish leaves, which ai-e invested with an appressed and 

 often yellowish tomentum. The heads are very small and the tips of 

 the staminate bracts are rather firm in texture and inclined to be folded 

 back. The type of the species is a form with acute, green, pistillate 

 bracts and greenish brown staminate ones. Dr. Rydberg based his 

 A.favescrns{xio. 5145. the type of this, is composed of staminate plants.) 

 on specimens which as to habit and leaves are essentially those of the 

 type of ^1. rcfle.ra. The l)racts, however, are lighter in color.

More or less sutfrutescent, the stems slender, about 1 dm. high, 

 rarely 15 cm.; leaves mostly oblong- spatulate, obtusish to acute, about 

 1 cm. long, rarely longer, tomentose on both surfaces and dull in color; 

 involucres 4-5 mm. high, the bracts few, the tips of the pistillate ones 

 oval to oblong, obtuse, brownish yellow to dull white, tips of the stam-

 (Leiberg, no. 331; Cusick. no. 1924), and Idaho (Henderson, no. 3514). 



Nearest to ^1. rclle.fa and replacing it west of the Rocky ^Mountains. 

 It approaches very closely to that species, yet the typical form is quite 

 ditt'erent in being more distinctly sutJ'rutescent and slightly viscid 

 throughout and in having " oblong-spatulate " rather than spatulate 

 lea\es and lighter-colored involucral bracts. It is very similar to ^1. 

 arida^ being distinguished from the latter h^ its suffrutescent habit, 

 viscidulous leaves and stems and pale brown bracts.
