 A small rigid glabrous grass, with a long wiry creeping

 •concave, pungent; spikelets ovoid, laterally compressed, i-fld., 

 articulate on very short stout pedicels, appressed to a rigid

 glumes 2, I empty, rigidly coriaceous, margins closely ap- 

 pressed, as if connate, and tip membranous, veins o, II much 

 smaller than and completely enclosed in I, ovate-lanceolate, 

 hyaline, 1 -veined, palea linear-oblong, hyaline; lodicules o;

 I and II empty, I coriaceous, incumbent on II, formed of 

 a globose base and narrow elongate limb, base and keel of 

 limb crested by a narrow cartilaginous wing which is pecti- 

 nately ciliate with long hook-tipped spinules, limb narrowly 

 cymbiform, acute, II much smaller than I, coriaceous, lanceo- 

 late, acute, keel crested like I, III bisexual, most minute,
