DESCRIPTION. 



Root perennial, multiple, — fibrous. 



Stems 2 feet or more high, 1 to 4 or 5 from the same root. 

 The central one erect, the others smaller and more or less 

 declined, purplish below, clothed with whitish, bristly hairs, that 

 are dark colored at the base. The hairs are more numerous 

 toward the base of the plant, mixed in the upper part of the 

 stem with glandular hairs, dark colored, shorter, which become 

 abundant on the flower pedicels and involucre. Mr. Ward and 

 also Dr. Gray describe the upper part of the plant as free from 

 hairs, but our specimens show scattered hairs the whole length 

 of the stem and they are also mixed with the glandular hairs on 

 the flower pedicels and on the scales of the involucre. Spread- 

 ing by means of stolons as shown in the plate and also by root- 

 stocks w 7 hich connect different plants below ground. 



Leaves lanceolate with a winged petiole, margin more or less 

 wavy with scattered small, dark-colored teeth. Pale green 

 both sides and armed above and below with scattering long, 

 white hairs, which show a dark base on the mid ribs, and some- 

 times on the other parts. Radical leaves many, making a dense 

 mat on the ground in the patches. Stem leaves smaller, nar- 

 rower, 2 to 4, located on the radical half. 



Infloresence paniculate or cymose. On the larger plants 

 with many heads; those on the lower pedicels open first, and 

 when the pedicels branch, the lower heads on the branches are
