Sessile Spikelet. 



Glume I. — Lanceolate, 2 lateral keels, dorsally flat or depressed between the keels. 

 Apex 2-mucronulate. 

 One or both margins incurved. 

 Dorsally scabrid on keels, otherwise glabrous, or more or less villous 



dorsally. 

 Villi not overtopping the glume, or overtopping by less than ^ glume's 



length. 

 Two nerved, sometimes with 1—2 additional faint nerves between the 



keels. 

 Glume II. — Subequal to I. A central keel. 

 Mucronate. 



Margin incurved ciliate. 

 Dorsally scabrid on keel, otherwise glabrous or more or less villous 



dorsally. 

 Villi not overtopping the glume, or overtopping by less than \ length of 



glume. 

 One nerved and sometimes one or two partial lateral nerves. 

 Glume III. — Slightly shorter than II. 



Oblong-lanceolate, hyaline. Apex mucronate or acute. 



Glabrous dorsally. 



Margin incurved, ciliate above. 



One — three nerved. 



Glume IV— Usually f III. 



Ovate-lanceolate, hyaline. 



Margin incurved, ciliate. 



Long-awned. Awn 0-10 to 0-23 in. long. 



Three nerved. 

 Pale. — About f IV, ovate-lanceolate, hyaline, glabrous, enerved. 

 Lodicules, two, cuneate, glabrous. 

 Anthers, three, -05 to -07 in. long (0-08 to 0T0 in. fide Hackel) yellow, streaked with 



purple. 

 Stigmas 03 to -06 in. long. Yellow. 



Pedicelled spikelet is similar except that glumes I and II are often strongly three 

 nerved and both glumes I and II are more densely villous dorsally. Villi not overtopping, 

 or overtopping by less than \ spikelet's length. 



This species is not infrequently mistaken for Saccharum Munja, but is easily distin- Fiew ch»ra C 

 guished by its distinctly awned spikelets, the broader dark green leaves and hairy leaf- 

 sheaths. The fruiting panicle also is usually browner in colour.
