Fool perennial. Stem erector spreading, pubescent, 1 — 3 feet 

 long. Leaves obiong, generally obtuse, sometimes acuminate. 

 Peduncles rarely shorter than the leaves. Bracts much longer 

 than the calyx, ovate-cordate. Segments of the calyx lanceo- 

 late. Corolla white. Stig7nas oblong. 



Hab. In dry woods. About 3 miles from Brooklyn, Lbng- 

 Island, on the Jarhaica road. In the pine barrens of New-Jer- 

 sey. In the western parts of the State of New-York. Ste- 

 ve ?is on and Had ley, &c. June. 



I cannot distinguish any essential difference between C. s/ii- 

 thamxus and stuns. The leaves vary from acuminate to ob- 

 tuse, and the length and insertion of the peduncles are by no 

 means constant. Muhlenberg, however, has not united 

 them.
