side, the base distincetly undulate and hispid; ligule membranaceous, about 6 mm. 
long, jagged at the apex and margin, or breaking up into fibres. 
Panicle rather compact and dense, the numerous capillary branchlets mostly 
verticillate, the whole inflorescence about 25—30 cm. long. 
Fertile spikelet 4—$ mm. long, silky-hairy, the pedicel also more or less covered 
with silvery hairs, outer glume 7—9 nerved, scarious at the apex, 2nd glume keeled, 
3—5 nerved, more or less hairy, with a thin or membranous apex; palea acuminate,
