 its densely tufted habit of growth, very much smaller size, narrower leaves, rather 

 lax, depauperate panicle, solitary or at most paired panicle-branches, and larger 



spikelets.

Dense caespitosum, culmis gracilibus, teretibus, usque ad 2 m alt is, 2 

 ad 3 mm diametro; foliis radicalibus nullis, caulinis 2 vel 3, brevibus. 

 verticaliter compressis, 1 ad 5 cm longis, vix 3 mm latis ; inflorescentiis 

 laxis, 10 ad 15 cm longis, "zigzag"; spiculis brumieis, circiter 2 mm 

 longis; fructibus ellipsoideis, teretibus, admodum nitidis, mgosis, apice 

 truncatis. 



A densly c^espitose plant from creeping rhizomes, the culms rush-like, 

 often nearly 2 m high, sometimes shorter, terete, glabrous, 2 to 3 mm 

 in diameter, their bases covered with several short, imbricated bracts, 

 leafless except for the 2 or 3 culm leaves which are much reduced or 

 sometimes represented only by sheaths, or sometimes 5 cm long, always 

 less than 3 mm wide, vertically compressed, glabrous. Panicles 10 to 

 15 cm long, interrupted, thyreoid, lax, both the primary and secondan- 

 rachises strongly zigzag, on the ultimate branches each group of two or 

 three spikelets subtended by an ovate, keeled, brown, prominently acu- 

 minate bract about 3 mm long, the basal portion broad, 7- to 9-nerved, 

 the spikelets sessile or shortly pedicelled, crowded. Spikelets brown, 

 glabrous, 2 to 2.5 mm long, each bearing a single perfect flower, the glumes
