linear to cuneate or subclavate, dorsally compressed, glabrous, contiguous or 

 nearly so ; disarticulation of the joints at a right angle to the rhachis, their 

 tips more or less hollowed out, with or without an ear-shaped appendage. 

 Sessile spikelet dorsally compressed, the narrow transverse callus fused with 

 the base of the adjacent joint and pedicel into an obscure rim from the 

 centre of which protrudes a knob fitting into the hollow of the next lower 

 joint, the whole plexus falling together. Florets 2, the lower usually reduced 

 to the valve with a small valvule, always neuter upper bisexual, awnless. 

 Glumes subeqnal ; lower flat or slightly convex on the back, smooth or 

 variously sculptured, with narrow inflexed margins, 2-keeled npwards and 

 more or less winged from the keels, obtuse or emarginate, very faintly nerved ; 

 upper chartaceous, keeled, acute, 1-3 nerved. Valves hyaline, of lower floret 

 2-nerved or nerveless, of upper 3-1-nerved or nerveless. Valvule hyaline, similar 

 to the valve, 2-nerved or nerveless. Lodicules 2, cuneate. Stamens 3. Stigmas 

 shortly laterally exserted. Grain oblong, dorsally compressed ; embryo about 

 half the length of the grain. Pedicelled spikelet very varied, similar to the
