Eupatorium: dedicated to Eupator Mithridates, who is 



said to have used this species in medicine. 

 Perfoliatum: Latin denoting through the leaf. 



THE PREFERRED HABITAT: ditches and damp ground. 



THE PLANT: erect, two feet to five feet high, branched 

 above; the stem stout with short, soft hairs. 



THE LEAVES: opposite or rarely in threes, four inches to 

 eight inches long, one inch to one and a half inches wide; 

 wrinkled and with short, soft hairs on both surfaces; 

 tapering to a point at the apex; larger at the base and so 

 grown together that the stem appears to pass through 

 them; toothed. 



THE FLOWER HEADS: crowded in a modified panicle, 

 small; involucre bell-shaped; its bracts lanceolate, acutish, 

 overlapping in two or three series, covered with short, 

 soft hairs, the outer ones shorter. 



THE FRUIT: achenes; pappus consisting of bristles. 



This is that tall, rather heavily-stemmed plant of the 

 ditches and damp ground, with purple-tinged, heavy, 

 opposite leaves, through which the stem passes, and large, 

 whitish flower heads that are increasingly fuzzy ani in- 

 creasingly grey as they mature. But not for any grace
