 by stolons and offsets. Stem and midrib on the under surfaces of the 

 leaves densely downy-pubescent. Basal and lower stem leaves spatulate 

 or obovate, dentate, 1 to 3 inches long, blunt at the apex, narrowed 

 at the base into short petioles; upper stem leaves cordate-clasping and 

 smaller. Heads of flowers one-half to 1 inch broad, in a corymbose panicle, 

 borne on slender peduncles thickened at the summit. Each head with 

 one hundred to one hundred and fifty ray flowers, one-sixth to one-third 

 of an inch long, fringelike, light rose-purple to pinkish in color, surrounding 

 a yellow center of disk flowers. Involucres of the heads depressed-hemi- 

 spheric, composed of narrow, linear bracts, pubescent and with dry, 

 membranaceous margins. Buds drooping, but flowers borne erect.
