Oryza sativa Linn. 
The common wild rice of Ceylon is a perennial, and also differs 
from the cultivated O. sativa in the narrow glumes and exserted 
styles. Some specimens in the herbarium are labelled : 
O. LoNGISTAMINATA A. Chev. & Roehrich, in Compt. Rend. CLIX, 
p- 561 (1914). O. sativa Hk. f. in Trim. FIl.-Ceyl. V, p. 182 (1900) 
pp. non Linn. O. fatua var. longiaristata Ridl. Fl. Mal. Pen. V, 
Pp. 252 (1925) pp. | 
W. Ferguson (m.s. in Herb. Perad.) notes that the rhizomes may 
be as long as 12 ft. 
Ridley (Fl. Mal. Pen. V, p. 252) considers that the parent of the 
cultivated rice was an awnless species which he calls O. fatua Keen. 
and makes the plant wild in India var. longearistata. 
A specimen collected at Batticaloa by Nevill has broader glumes 
and is probably the species or variety called Pundi-nel which may be 
O. rufipogon Griff. Not. III, p. 5 (1851); Ic. t. 145, f- 2 (1844). 
Mr. Hubbard, in litt., apparently considers both plants to be 
O. fatua Koen.
