blades flat, nearly smooth, twisted, 10-17 cm. long, 3-4 mm. wide, 

 the tips slender. Spikes light green, rather dense, 5-8 cm. long, 7 

 mm. diam. Spikelets 2-4 in a cluster, having 2-3 bristles (3-10 

 mm. long), each with asperities pointing upwards, oval, almost 

 pointed, gibbous, 2.5 mm. long, first glume half the length of the 

 spikelet, 3-nerved, second but little longer than the first and 5- 

 nerved, third 5-nerved, as long as the fertile floret and including a 

 palea of its own length ; fertile floret very slightly wrinkled trans- 

 versely when seen with a lens. Index Kewensis includes this under

Culms smooth, stout, branched, 90-240 cm. high. Leaf-blades 

 flat, rough, lanceolate, 20-40 or more cm. long, 15-25 mm. wide. 

 Spikes compound, green or purplish, the rays well filled and con- 

 tiguous, or the lower ones a little distant, nodding, 20-40 cm. long, 

 15-25 mm. diam., bristles 1-3 for each spikelet, with asperities 

 pointing upward, very variable in length. Spikelets narrowly obo- 

 void wlien in flower, 3 mm. long, first glume one-third the length 

 of the spikelet, 3-nerved, second three-fourths as long as the spike- 

 let, 5-7-nerved ; floral glume of the neuter floret 5-nerved, its palea 

 small or wanting; fertile floret finely rugose transversely under a 

 lens. 



A very variable plant, as might be expected when we consider 

 the wide range of soil and climate in which it is cultivated. 



Introduced from the East Indies. For a more extended account
