33. Oryza.] 139. GRAMINEJE. 



7-9-nerved ; palea (gl. iv of most authors) as long as the glume, 

 keeled. Lodicules 2, 2-lobed, rarely entire. Stamens 6, anthers 

 linear. Styles short free, stigmas laterally exserted. Grain narrow, 

 free or adnate to the glume and palea. 



The spikelet of Oryza has been variously construed. The above is the account 

 (with few modifications) as given by Hooker in the F.B.I. Dr. iS^^r/)/ considers 

 that the usual 2 outer empty involucral glumes are absent, that the next 2 (scales 

 or bristles) are empty florets (valves); they fall with the fruit. He also considers 

 the fourth glume a palea. 



Cooke describes the floral glume as 5-9-nerved. It is only 3-nerved in the 

 common wild rice unless the strife be counted when it is many nerved.

cultivated varieties. 

 Annual with creeping or floating and erect stems 2-10 ft. Leaves 

 1-2 ft. by •25--3" or more, striate, scaberulous. Sheaths smooth, 

 ligule long 2-partite. Spikelets awned in the wild plant, shining, in 

 finally drooping panicles. Gl. i and ii J-^ length of iii lanceolate ; 

 iii hispid above, dorsally spinescently ciliate, striate with minute 

 dots. 



'J'he wild plant occurs in marshy localities in various districts, especially 

 Sambalpur, Chota Nagpur and the Santal Parg. ! Cultivated in all districts 

 in both lands which are irrigated or submerged during the rains and on non- 

 submerged lands. For accounts of the different varieties and crops see Watt 

 {Diet. Ec. Prod., v, 502 et seq.). - 



The following is a more special account of the wild rice collected 

 in our area : 



Lower parts submerged. L. 6-15" long, •25-"4" broad, margins very scabrid 

 with minute bi'istles, sheaths inflated many-nerved, ligule erect --l-'o" long with 

 <in my specimen onlj') two lateral long su])ulate ciliate fleshy processes at its base 

 in the angles between the sheath and the blade. Panicles rather eflluse, sometimes 

 scarcely exserted from the uppermost leaf-sheath (but my specimen is only in 

 flower). Spikelets •25-*27" long, yellow, shortly pedicelled on the flexuous scabrid 

 branches, long awned. A half -annular thickening below glume i may represent 

 the rudiment of a suppressed glume. Gl. i lanceolate pale "l" long keeled acuminate, 

 not laterally compressed, margins scaberulous ; ii similar and subequal rather 

 distant on the much thickened rhachilla, rhachilla with a callus thickening between 

 ii and iii ; iii sparsely hispid and minutely closely granulate or punctate, much 

 laterally compressed, cymbiform keeled and with two lateral ridges, many-striate ; 

 apex with pink glandular swellings and then terminating in a hispid awn 2'5-3" 

 long, palea similar in texture, markings, spinulose hairs and glands, but more 

 oblong (less deep), equal or a little longer, with white margins to which the sub- 

 quadrate lodicules are partlj-^ adnate each side. Ovary only 'OS-'Oi" long. Grain 

 not rii^e.

Rootstock woody. Stems slender round polished tufted. Leaves 

 lanceolate-linear, attaining 9" by -1" but mostly much smaller and 

 only about 2-3" by -2" near top of stem, nerves 2-5 each side of 

 midrib, sheath very long smooth striate with a very short ligule and 

 ciliate auricles. Spikelets •2--25" on the flexuous rhachis of very 

 slender long-peduncled simple or nearly simple racemes, rarely a
