This plant, probably an emigrant from Europe, has over- 

 run the vicinity of this place, and grows in almost every kind of 

 soil. It begins flowering in June and July, and is nearly the 

 last plant that yields to the frosts of November, Root abrupt. 

 Leaves all radical, spreading, lanceolate, more or less toothed 

 and pinnatifid, according to the soil in which they grow, usually 

 curving to one side. Scape spreading, bending upwards, fur- 

 rowed, branching into a few peduncles, which are furnished 

 with scattered, remote scales, and are hollow, like many others 

 of the class, with a minute tuft, like cotton or cobweb, at the 

 base of their cavity within. Flowers yellow, resembling those 

 of the dandelion. The scales on the stalks and calyx are less 

 numerous than in the European variety.
