Siibctespitose. Rootstock rather shortly creeping. Flowering stems 
few or rather numerous, erect, straight, usually sharply curved or geni-" 
culate at the base, slender, not rigid, smooth, glaucous ; tlie uppermost 
knot one-third or one-fourth above the base, rarely near the middle ( ?). 
Leaves narrowly linear, narrowed upwards, gradually pointed and 
hooded at the apex, glaucous ; sheaths nearly smooth, ancipitate, the 
uppermost one about as long as its leaf ; ligule about twice as broad 
as long, obhquely-truncate, obtuse. Panicle erect, or slightly secundly 
drooping, more or less distichously unilateral (particularly in small 
examples), rhombic-triangular in flower, oblong or linear iii fruit. 
Panicle-branches 2 to 5 at the lower nodes of the rachis, but usually 2, 
not rigid, spreading-ascending or ascending in flower, erect and often 
adpressed in fruit, the longer ones bare of spikelets and unbranched at 
the base for from one-third to one -half their length, scabrous. Spike- 
lets elliptical, 2- to 5-flowered, but usually 3- or 4-flowered. Glumes 
acuminate, the larger one as long as or even a little longer than the
