 18. ORITZA* Linn. 



Leafy tall grasses. Leaves long, flat. Spikelets jointed on the slender 

 branches of an elongate rarely spiciform panicle, 1-fld., oblong, laterally 

 compressed, pedicels ajWMrfSTr at the top. Glumes 2-3, I and II much the 

 smallest, empty, scale or bristle-like, rarely 0; III chartaceous, obtuse 

 acute or awned, strongly 3-5-nerved ; palea as long as the gl., keeled. 

 Lodicules 2, 2-kibed, rareiy-efHiire. Stamens 6, anthers linear. Styles 

 short, free ; stigmas laterally exserted. Grain narrow, free or adnate to 

 the gl. and palea. Species 5-6, tropical. 



The gl. IV of most authors, is here considered to be a palea, as Is indicated by 

 the positions of the lodicules and stamens in relation to it.

Annual. Stems 2-10 ft., creeping or floating. Leaves 1-2 ft. by -5 in. or 

 more, flat, striated, 1-nerved, scaberulous; sheaths smooth. Panicle at length 

 drooping. Spikelets not imbricating, awn 3-5 in. long, yellow or reddish, shining. 

 I have described above the plant which Roxburgh and other Indian authors consider 

 to be the indigenous Rice, and who have collected it as such in the localises 

 mentioned above, as I have in hot valleys of Sikkim and the Khasia Hills. It 

 resembles in all essentials a commonly cultivated awned sort. I have seen no 

 specimens of Griffith's 0. rufipogon, which he describes as a very different-looking 

 plant, but his characters are not diagnostic, and a memorandum by Munro (in Herb. 

 Kew) states that he can find no real distinction for it. For the cultivated varieties 

 of Rice in India, see Watt. " Dictionary of the Economic Products of India," vol. v.

 a cultivated form.
