FIELD AND WOODLAND PLANTS 



The Black Knapweed. 



three-quarters of an inch in 

 diameter, arranged singly 

 on the tips of the branches, 

 or on stalks arising from the 

 axils of the upper leaves. 

 The florets of the ray are 

 spreading, and much longer 

 than those of the disc ; and 

 the fruits have a minute 

 cup at the top, from the 

 inside of which spring 

 the hairs of the pappus. 

 The smoke arising from 

 the burning Fleabanes was 

 supposed to kill fleas and 

 other vermin; and the 

 specific name dysenterica is 

 due to the fact that this 

 species has been used as a 

 medicine in cases of 

 dysentery. 



The Small Fleabane 

 (/. Pulicaria) is a 

 similar plant, but 

 smaller (from six to 

 twelve inches high) 

 and less woolly. Its 

 flower-heads are yel- 

 low, much smaller, on 

 terminal and axillary 

 stalks ; and the florets 

 of the ray are only 

 sHghtly longer than 

 those of the disc. 

 The hairs of the pap- 

 pus are not surrounded 

 at the base by a Uttle 

 cup, but by a few 

 minute and distinct 

 scales. This species 

 grows in the south- 



THE GUEAT Knapweed.
