lanceolate, acute, remotely but distinctly serrate-toothed, — 
sessile, sparsely and strigosely pubescent with short hairs, - 
the margins near the base ciliate with a few short stout se- —

A most distinct prairie species, of apparently limited range

radical, somewhat fleshy, light green, glabrous except a Very 
distinct arachnoid white tomentum on the margins of the 
dilated bases of the long slender petioles, the blade of such 
leaves from spatulate-obovate and oval to round ovate, 
mostly erenate or serrate-toothed, rarely entire; cauline 
leaves-few, sessile and pinnatified, often lyrately so: involu- -
