 of the calyx larger, ovate, acute, keeled; coralline valves of the hermaphrodite equal, 

 whitish ; outer ovate, acute, somewhat keeled, concave, the other flat, included. 

 Filaments very minute. Corolline valves of i..e male barren ; outer large, ovate, acute, 

 concave ; inner minute, flat. Seed ovate, inclosed in the corolline giuriies 61 the her-

 shorter than the corolla, and retuse, the third the same length with the 

 corolla. 



Culm from one to three feet high, simple, round, wen; leaves broadish, not long, 

 acute, erect, rugged at the edge, striated, sheathing at the base ; the neck beardless ; 

 rachis terminating, almost a foot long, simple, linear. Spikes five or six, alternate, 

 sessile, pressed to the rachis, directed one way ; florets sub-sessile, approximating, in 

 two rows on the same side, ovate, whitish. Two valves of the calyx equal, ovate, 

 blunt, awnless; the third very small, roundish; valves of the corolla smaller, oblong; 

 etignias purple; seed fastened to the corolla, roundish &8). 



4. P1LOSUM. HAIRY. 



Spikes panicled, alternate, directed one way ; spikelets rn pairs, one smaller, 

 acuminate, even ; rachis compressed, hairy ; culm divaricate, jointed. 

 Culm three or four feet high, branched, compressed, even; joints villose, large; 

 leaves lanceolate, acute, even, rugged at the edge. Sheaths approximating, com- 

 pressed, villose at the base ; peduncles from the sheathing internodes, compressed, 

 short. Spikes rigid ; rachis linear, compressed, hairy; hairs long, thin, spreading; 

 spikelets pedicelled, alternate, sharpish, somewhat cempressed, striated. Outer caly- 

 cine valve minute; inner ovate, nerved, concave; valves of the corolla ovate, very 

 tender; anthers purplish ; stigmas whitish ; seed oblong, compressed a little, small;
