Root perennial. Stem one to two feet high, simple, sparingly clothed 

 with long lanuginous hair. Leaves clothed in a similar manner, particular-

two-cleft at base, with the terminal appendix lanceolate, white. Stigmas 

 glandular. Seeds oblong, villous. Fappus on all of the florets double, the

in this genus. 



Grows in dry sandy soils. 



Flowers August — October. 



The species which has been sent me from New-Jersey by my much 

 teemed friend Dr. Torrey, of New-York, as the Inula Falcata of Pursh, is 

 certainly a very distinct species from this. It may be distinguished as C. 

 falcata foliis iineari-lanceolatis, acutis, rigidis, sub falcatis ; involucri squa- 

 niis sub toraentosis. The flowers in my specimens too are smaller than 

 those of the C. Mariana.
