Rhizoma lignosum, perenne. Culmi 3-6 dm., approximati, 
irigoni. Folia elongata, plana, in marginibus minute seabra; 
vagin: aphylle fusce. Inflorescentia 2-3 dm. longa, lanceolata, 
laxa. Spice terminales ssepius spiculis masculis, multifloris, 
5-10 mm. longis instructz. Spicule androgyne longe 8 mm., 
3-7-floree, flore imo femineo, ceteris masculis. Spicule 1-flore 
femine: haud raro obviæ sunt, ideoque spice specie androgyne 
basi 2 spiculis foemineis instructe videntur. Gluma feminea
