Stem two to three feet high, acutely triquetrous, serrulate along the mar- 

 gins. Leaves four to seven lines wide^ rather longer than the stem, chan- 

 nelledj very acute, scabrous on the upper surface, the margins and midrib 

 serrulate, sheathing at base. Flowers in distinct spikes, the sterile superior, 

 one to five, alternate, terete, sessile, one to two inches long; fertile spikes 

 two to three, remote, nearly sessile, erect, cylindrical, the fruit expandmg* 

 Of the sterile florets the bracteal leaf is setaceous or subulate, the lower lon- 

 ger than the spike, the scale lanceolate, rather obtuse, the midrib rufous. 

 Stamens three. Of the fertile spike the bracteal leaves' resemble the root 

 leaves, are very long, and have little or no sheath. Scale lanceolate, slightly 

 mucronate. Corolla ovate, inflated, nerved, acuminate, pubescent, a little 

 longer than the scale. Stigmas three- Seed obtusely triquetrous. 



Our plant is larger than the specimens sent me from Pennsylvania by l>r» 

 iMuhlenberg, and the fruit less hairy. Does it belong to this section? 



Grows in deep swamps; to me rarej found in fresh marshes along the 

 Ogeechee river. 



Flowers in April. *
