Perennial. Leaves eight to ten inches long, smqoth, very glabrous, 
somewhat lucid, nerveless. Scape 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. 
Flowers May— August.
