90 Rudbeckia triloba. 



ly three-nerved, hairy on each side, and ciliated on the margin, the 

 cilise longest towards the hase. Stem and branches cylindrical, fine- 

 ly lined, generally greenish on one side and purplish-red on the 

 other, or entirely dull-lake-red. Flowers small. Calicine leaves 

 linear, nearly or often quite as long as the rays, acuminated, and 

 hairy. Rays emarginated, lanceolate, elliptical, gamboge-yellow. 

 Disk auricula-purple. Scales of the receptacle awned. Flowers 

 in August and September. " In the mountains of Virginia and Caro- 

 lina." Fursh. " In the New England states." Eaton. 



Another species of the beautiful autumnal genus Rudbeckia, al- 

 ready fully described in preceding pages, is here figured. It is 

 rare in Pennsylvania, though sufficiently common to the south 

 and westward of this state. The flowers of this, are smaller 

 than those of the other species, none being found much larger than 

 the drawing represents. For the specimens from which it was 

 made, I am indebted to Mr. Nuttall, who raised plants of it last sum- 

 mer in this city. 



The plate represents an upper portion with one of the three-lobed 

 leaves, in its natural situation — the size of nature.
