much creeping. Inflorescence truly lateral, near the extremity of the 

 stalks, which are very variable in size, 2 — 6 or 8 feet high, and as 

 thick as a finger at the base. Spihehts often almost sessile. Glumes 

 brown, fringed. Stigmas 2 — 3. Fruit obovate-triquetrous, accom- 

 panied by 5 or 6 bristles. The stems are much used for mats, chair-

 their spongy nature well adapting them to that purpose.
