These two species are considered by our Botanists now as mere varieties. 

 I liavcj therefore, placed them together. 



Stem very variable in size, three to seven feet high, robust, very hairy, 

 bl'anching very profusely towards the summit. Lower leaves sessile, lan- 

 ceolate, acute, very rugose, very scabrous on the upper surface, scabrous 

 and hairy underneath, more or less coarsely serrate; upper leaves generally 

 ovate, with a few serratures. Flowers in large almost corymbose panicles, 

 composed of small recurved branches. Scales of the involucrura linear- 

 lanceolate, nearly glabrous. Florets of the ray rather small. Seed pubes- 

 cent. 



There are certainly some remarkable varieties included under this species; 



a few I shall enumerate. 



a. RuGOSA- Muhl. Stem about three feet high, villous. Leaves finely^ 

 serrate, less rugose than those of the other varieties. Flowers in a pyra- 

 midal panicle. 



i. Stem hairy, rough. Leaves very rugose. Lateral branches of the pani- 

 cle long, slender, slightly recurved. . 



C. Stem and leaves similar to the last. Branches more robust, producing 

 numerous recurved racemes; each branch forming a long cylindrical mass 

 of flowers. ■ 



«f. Stem softly pubescent. Branches scattered, divaiucate, recurved, nearly 

 simple. 



Grows in damp rich soils. 



Flowers September — October. '
