 about 5 pairs of sjjikelets : sterile spikelet large, many-flowered, ses- 

 sile within the superior fertile scale ; stamens 3. Nut obscurely 3-sided, 

 somewhat shining, white, roughened with remote warts, not wrinkled 

 or pitted ; stipitate prominences at the base very few. Pcrigynium a

Hab. Damp soils. South Carolina, Elliott ; Southern 

 States, Dr. Baldwin! ; Georgia, Le Conte! 



Obs. Darlington refers S. ciliate to his S. paitciflora ; 

 but the plant described above is quite distinct from the latter 

 species, which I received from the author himself.
