 grayish throughout from a white, cottony wool, glandular above. 

 Leaves at the base narrowed to broad petioles, lanceolate, veiny, 

 entire or toothed, 3-4 in. long; upper leaves sessile by broad, 

 clasping bases, diminishing upwards. Inflorescence cymosely

 to be undescribed. 



Whitneya dealbata Gray. Perennial, with several stems 

 from the root, hoary throughout from a dense, white, matted

 together about 3 in., entire ; stem leaves narrow, sessile, united at 

 base. Heads 2-3 in. across, the rays 3-toothed at apex, becoming 

 more than an inch long and almost half an inch wide. This 

 handsome plant grows in the shade of the conifers, and was col-

 or more long, wedge-shaped, with 3 or 4 blunt teeth at apex;
