	Antennaria rosea	Antennaria media
		alpine pussytoes, Rocky Mountain pussytoes
Habit	Dioecious, mat-forming, stoloniferous perennial 5-40 cm. tall; stolons up to 10 cm. long, decumbent; upper surface of the stems with stalked glands, the hairs white or purple.	Mat-forming, stoloniferous perennials seldom over 1 dm. tall
Leaves	Leaves 1-nerved; upper surface of the leaves covered with silvery-white hairs; basal leaves spatulate or oblanceolate with a wedge-shaped base; cauline leaves linear, alternate.	Basal leaves oblanceolate, up to 2.5 cm. long and 7 mm. wide, densely white-woolly on both sides; cauline leaves small and linear.
Flowers	Heads several in a sub-capitate cyme; pistillate involucres 4-10 mm. long; scarious portion of the involucre bracts white, straw-colored or light yellow.	Heads several in a sub-capitate inflorescence; pistillate involucres 4-7 mm. high, woolly below, the scarious tips of the bracts dirty blackish-green, at least the inner slender and pointed; scarious portion of the bracts in staminate flowers often with white tips.
Fruits	Achene.	Achene terete

Identification notes		The small leaves and narrow, pointed involucre bracts should separate this species from others that might be found at high elevations.
Flowering time	June-August	June-September
Habitat	Dry to moist habitats, including meadows, ponderosa pine forest openings, rocky slopes, and floodplains from the lowlands to the alpine.	On rocky slopes and ridges, and in talus and pumice, from subalpine to alpine meadows.
Distribution	Occurring on both sides of the Cascades crest in Washington, but more common east of the crest; Alaska to California, east to the Rocky Mountains and northern Great Plains, Great Lakes region, and eastern Canada.
