1 82 Graminece. \Oryza~ 



Very closely allied to A. laxiflora, differing in the much stiffer branch- 

 lets of the panicle and pedicels, and broader, thicker glumes I and IL 

 The specimens numbered C. P. 4019 are small, with no habitat attached. 



A. brasi/iensis, Raddi. Ceylon is given as a habitat in Fl. B- 

 Ind. (vii. 73) for this plant, some specimens of A. laxiflora having been 

 taken for it. It is a very common and variable species found in both 

 hemispheres, abounds in the hilly districts of India from the Himalayas 

 southward, ; nd may be expected to occur in Ceylon. In habit it is a. 

 much stouter plant than A. laxiflora, with larger, shorter pedicelled 

 spikelets, but it is very difficult to formulate their differential characters. 



15. ORYZ.A, L. 



Tall, annual or perennial grasses; 1. long, narrow, flat;, 

 spikelets i-fld., loosely arranged on the branches of a raceme 

 or panicle, disarticulating from their pedicels, laterally strongly 

 compressed, awned or not, thickened at the base; glumes 1-3,. 

 I and II very minute, subulate or o, III dimidiate-oblong,, 

 coriaceous or chartaceous, hard, keeled, 5 -veined, the lateral 

 vein forming a thickened margin of the glume, awnless or 

 with aiong or short straight terminal awn, which is scabrid 

 and articulate on the glume, palea linear, as long as the 

 glume, 3-veined, coriaceous with membranous margins ; 

 lodicules 2, entire or 2-lobed; stam. 6; styles short, free,, 

 stigmas penicillate, laterally exserted from the glume; grain 

 narrowly oblong, compressed, closely invested by or adnate 

 to the glume and palea. — Sp. 5 or 6 ; 5 in Fl. B. Ind. 



Dr. Stapf, who has made a careful study of the morphology of the 

 spikelets of Oryza, informs me that it consists theoretically or normally 

 of 5 glumes, of which the two lowest are very minute, are confluent with 

 the tip of the pedicel, and rarely discernible. The spikelet is hence only 

 apparently articulate with the pedicel, the real articulation being above 

 these two suppressed glumes. The two following glumes, also empty, 

 are always minute, and one, or rarely both, are sometimes suppressed. 

 The palea is very anomalous, being 3-veined and as coriaceous as the 

 uppermost glume. Rarely a sixth glume is produced ; it is like the fifth, 

 but narrower and empty; its palea is 2-keeled, as in most grasses. Dr. 

 Stapf refers (in Flora Capens.) the Tribe OryzecB to the Group Poacece^ 

 and places it near Pappophorece and Phalaridece.
