	Antennaria rosea	Antennaria lanata
		woolly 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.	Perennial from a short woody base, not rhizomatous, 1-2 dm. tall, densely and persistently white-woolly throughout.
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 erect, tufted and persistant, 3-10 cm. long and 3-10 mm. wide, usually with 3 main veins; cauline leaves linear, progressively reduced upward.
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 compact inflorescence; pistillate involucres 5-8 mm. high, white-woolly toward the usually greenish base, the scarious portion dark brown or greenish-black below, paler toward the whitish tip; staminate involucres similar but smaller.
