numerous, iiexuose, slender, in irregular fascicles. Sheathing 

 scales broad, appressed, produced into linear laminie of 3-G lines. 

 Male s'pikelets solitary, terminating numerous fascicled branch- 

 lets, the subulate bracts continuous, broadly ovoid, 2 lines long, 

 with numerous flowers. Glumes broad, brown with slightl}^ 

 scarious margins, shortly aristate, a few outer ones short and 

 empty. Perianth-segments 6, narrow hyaline, obtuse, the 2 outer 

 ones slightly complicate and longer than the others. Anthers on 

 long filaments. Female spikelets not numerous, sessile, solitarj'- 

 and terminal, the subtending bract continuous or 2, the second 

 sessile lower down, narrow-acuminate, 3 lines long. Glumes 5, 

 the 2 outer ones foliaceous, short, terminating in linear points; 3 

 inner ones rather long, ovate-lanceolate, acute, brown and slightly 

 hairy on the backs. Perianth-segments 6, thin, hyaline, broad, 

 notched at the top, shorter than the ovary. Style long, divided

Rhizome tufted. Stems very rigid, attaining a height of 4 feet, 

 terete below the inflorescence, striate, with a sheathing bract at 

 or above the middle, ending in a long leaf-like lamina. Leaves 

 terete or slightly compressed, not numerous, nearl}-- as wide as 

 the stems, quite erect, tapering into long slender points; sheaths 

 crow^ned at the summit with a small membranous margin. 

 Panicle very long and narrow, with numerous long, erect branches, 

 several together in each bract. Lower floral bracts with long 

 partially open sheaths, with a hyaline margin at the orifice and 

 ending in long, linear, flattened laminae, the upper ones becoming
