Not caespitose or loosely caDspitose. Rootstock exclusively creeping 
with long stolons. Stems solitary or subsolitary or fasciculate, 
erect or ascending, straight or slightly fiexuous, or geniculate at the 
base, firm. Leaves flaccid or firm, broadly linear, tapering to the 
apex, acute, flat, sometimes involute when dry, with numerous unequal, 
slender and non-contiguous, or thick cartilaginous and contiguous, 
scabrous ribs, with or without distant long or rather long soft

smooth on the angles, not fragile when dry. Spikelets 3- to 12- 
flowered, longer than the internodes, elliptical or elliptical-wedge- 
shaped or elliptical-hnear, compressed. Glumes commonly three- 
quarters the length of the spikelets, but sometimes not more than 
half their length, usually a httle shorter than the first floret, linear- 
lanceolate, acuminate, acute, or awned, or obtuse, strongly ribbed 
when dry. Lower pale linear-lanceolate, gradually pointed and acute, 
or obtuse, smooth, indistinctly 5-ribbed at the apex only, mucro-
