Perennial, Leaves eight to ten inches long; smooth, very glabrous, 

 somewhat lucidj nerveless* Scajie ten to fourteen inches high, furrowed, as 

 in all of the genus somewhat spiral, sheathed at base. Flowers in a very 

 compact head. Scales of the involucrum ovate, scarious, lucid, when young 



villous. 



On comparing the description of Michaux with a specimen now before 



me, it would seem that two species were now united under this name. 

 Grows in damp, poor soils — common around pine barren ponds.
