AKfc TIORTDS JAMAICENSIS. S3 



divided, spreading, almost upright, flexuose; florets very minute, pedicelled, pressed 

 close, approximating, ovate, bright green. Outer valve of the calyx less by half; 

 inner a little larger ; all ovate-acute, concave, striated, bluntly keeled at the edge, 

 appearing ciliate when magnified. Valves of the corolla in the hermaphrodite floret 

 equal, less than the calycine glumes, ovate, concave. Filaments very short, anthers 

 yellowish; stigmas blood-red; seed roundish, shining, extremely small. In the 

 neuter" floret the outer valve resembles that of the calyx. Native of Jamaica in dry 

 woods, flowering at the end of the year. Sw. 



12. FfcAVESCENS. YELLOW. 



Panicle simple, erect, stiff; branches snb-fasti^iate, the lowest opposite; 

 spikelets approximating, directed one way; pedicels two-flowered. 

 Height three or four feet ; culm simple, erect, round, at top compressed and pu- 

 bescent ; leaves long, wide, flat, entire, striated, spreading, even; sheaths close, 

 somewhat rough-haired-; branches of the panicle simple, alternate, spreading, the 

 lowest somewhat compressed, even. Florets pressed to the racbis, ovate, blunt, 

 smooth, yeliow; pedicels equal ; outer valve of the calyx only one-third the size of 

 the inner one ; both ovate, obtuse, concave, striated, pellucid; valves of the herma- 

 phrodite corolla ovate, concave. Filaments short; anthers small, purple; stigmas 

 villose, blood-red, seed oblong, shining, yellow. Outer valve of the outer floret 

 concave, ovate, striated; inner flat, more tender, whitish. This species is singular 

 in the colour, being constantly yellow, which, is not the case in the rest: it occurs, but 

 rarely, in dry places in tiie southern parts of Jamaica. Sw.

Culm afoot, sometimes two, in height, ascending, filiform, round, leafv, smooth; 

 leaves long, sharp, erect; sheaths striated, villose at the neck and throat ; knots pur- 

 ple; branches of the panicle alternate, flexuose, somewhat rigid. Florets rather dis-

 of the hermaphrodite corolla equal, less than the calyx, pellucid, whitish; anthers 

 purple; stigmas villose, blood-red; seeds roundish, yellow, shining. In the male 

 fl >ret outer valve ovate, acute, smooth; inner minute, flat, whitish; filaments one to
