This lias much the habit and aspect of 

 the corn C, but is usually a taller plant 

 and more downy, the leaves less divided, 

 with pinnatifid or toothed segments, the 

 flower-heads rather larger, and the rays 

 of a bright-yellow. 



In cultivated and waste places, in cen- 

 tral and eastern Europe and Russian 

 Asia, abundant in Denmark and eastern 

 France, but scarcely further west. In 

 Britain, said to be indigenous in some of 

 the eastern counties of England. Fl. end

 Receptacle small, not convex, with scales between the florets. Achenes 

 without any pappus. Style nearly that of Senecio. 



A considerable European and west Asiatic genus, divided by modern 

 botanists into two sections or genera, represented by the two British 

 species, but separated by very trifling characters. 



Leaves linear, serrated. Flower-heads few, hemispherical . 1. Sneezewort A , 

 Leaves much divided. Flower-heads numerous, small, and
