Perennial (rarely annual) glabrous grasses, erect or prostrate, or 

 creeping. Leaves narrow, flat or convolute. Spikelets 1-flowered, 

 small or minute, in effuse or contracted panicles, articulate on their 

 pedicels ; rhachilla not produced beyond the palea. Glumes 3, usually 

 membranous, 1-nerved or nerveless ; invol.-glumes empty, unequal, 

 separately caducous ; floral glume not articulate at the base, ovate or 

 oblong, obtuse or acute ; callus very short, glabrous ; palea as long as 

 the glume and o£ similar textui'e, broadly oblong, often dorsally 

 narrowly inflexed along the median line, with a nerve-like ventral
