margins with serrulated wings from the middle upwards,, 

 narrowly incurved above, very broadly below, II chartaceous, 

 lanceolate, acuminate, faintly 5-veined, dorsally smooth 

 rounded, and margins narrowly ciliate, III ovate-lanceolate,, 

 acuminate, 1 -veined, male or empty, palea lanceolate, thickened 

 with hyaline wings above, IV fern, or bisexual, broadly 

 2-lobed to the middle, 3-veined, lobes dimidiate - ovate,, 

 ciliolate, awn about \ in., palea linear-lanceolate, eciliate, 

 puncticulate ; styles rather short, stigmas very long, slender;, 

 pedicelled spikelet rather smaller than the sessile, glume I 

 lanceolate, acute, the wings coalescing in a fiat scaberulous 

 point, glume II-1V as in the sessile, but fern, only, and 

 ripening an ovoid-oblong grain.

As stated in Fl. B. Ind., I regard the Ceylon /. rivale as an endemic 

 glabrous-leaved form of the Khasian /. hirtum, with more than two 

 spikelets, and glabrous glume I. Dr. Trimen having kept it as a distinct 

 species in the Peradeniya Herbarium, I have followed him here. The 

 similarity of the sessile and pedicelled spikelets is as in Pollinia.
