This plant has proxctl \cr)- troublesome in northern New York 

 where it is regarded as even worse than the hawkweed. It has 

 been reported from several sections in Maine, especially in 

 Kennebec and Penobscot counties. The King-Devil weed is 

 of more vigorous habit than its relative, producing stems two 

 feet or more high, and from one to four or five from the same 

 root. The leaves are lanceolate with winged petioles, slightly 

 wavy margins, pale green both sides, and covered with scatter- 

 ing long, white hairs. The radical leaves form a dense mat on 

 the ground, killing out other vegetation. There are two to 

 four smaller, narrower leaves on the lower half of the stem. 

 The flower clusters are terminal and consist of four to twenty- 

 four yellow heads about one-half inch long. The difference in 

 color of flowers as compared with the orange hawkweed, is a 

 most noticeable character. The heads, also, are smaller and 

 more numerous than in the common hawkweed. The blossoms 

 usually appear about the same time as the fall buttercup, and, 

 as the flowers are of nearly the same color, the King-Devil 

 weed may escape notice when growing in grass land. A full 

 discussion of this weed was given by Professor Harvey in a 

 previous report of this Station.* 



TREATMENT. 



Remarks as to the treatment of the orange hawkweed will 

 apply with equal force to this plant. Treatment must begin 

 earlier in the season, however, and greater vigilance is neces- 

 sary to detect the presence of this species.
