558 COMPOSITAE (COMPOSITE FAMILY) 



Two other species of Hawkweed are becoming abundant in 

 eastern Canada and northern New York and New England. Both 

 promptly named "King Devils" by the farmers whom they vic- 

 timize. Hieracium floribundum, increasing by numerous stolons 

 and also by flowering branches at the base ; a smooth and glaucous 

 plant except that the spatulate leaves are bristly on the margins, 

 and sometimes on midrib and veins beneath. Heads in large 

 dense corymbs, yellow, with blackish involucres. Hieracium 

 florentmum, springing from a short stout rootstock, with smooth, 

 spatulate basal leaves or sometimes sparsely bristly beneath, the 

 scape often nearly two feet tall with manyheaded yellow corymb. 



Means of control 



Prevent seed production and distribution by close cutting of 

 flowering stalks while in early bloom. Cultivation of the soil 

 destroys the perennial roots. Like the Orange Hawkweed these 

 plants may be suppressed in grasslands by the use of salt.
