nebec 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 scattering 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 notice- 

 able 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 necessary 

 to detect the presence of this species.
