Three maiii types of facets may be distinguished, viz., ordinary 

 (Plate III, Fig. 1), membranous (Pkte 111, Fig. 2), and cihate 

 (Plate 111, Fig 3). In the ordinary type the facets are cup-hke, 

 the rim sometimes being thickened : in the membranous type the 

 margin of the facets is flanged or might be described as having 

 an expanded lip which is a membranous expansion. The ciliated 

 facets have short erect hairs on the margins of the facets. 



Each spikelet has three glumes, and a glume-like palea. The 

 outer glumes are usually small and sub-equal, not exceeding I — I of 

 the inner glume. The inner glume and palea are sub-equal. 



Clustered spikelets (17).— Although the spikelets are usually soht- 

 ary, in ' Baliia Baikonl ' (Raipur) and ' Benie ' or ' Jhingofri ' (Jubbul- 

 pore) the spikelets are clustered on the secondary branches, from 2-7 

 occurring close together (Plate IV). The branches of the panicle 

 have consequently a slightly interrupted appearance. The double 

 grained rice indicates a direction in which we may look for an 

 increase of the yield. 



Outer Glume8. — The outer glumes are usually small, coriaceous 

 and shiny. Glume 1 is inserted at a distinctly lower level than 

 glume II. Both glumes bear the impress of the facets of the pedicel. 

 The colour is usually somewhat paler than that of the inner glume 

 and palea, ranging from a pale yellow approaching white through 

 red to black. Ordinarily the outer glumes are inconspicuous, but in 

 • Boliita ' (Drug) and in ' Kalidhan (Iloshangabad) they are pale, while 

 the inner glumes and palea are black. Further in ' Bhojraj,' ' Naku ' 

 (Hoshangabad) and ' Ranikajar' (Jubbulpore) the outer glumes are 

 dark, while the inner glume and palea are light. The colours of 

 the outer glumes are useful in differentiating the varieties. 



Rachilla. — Between the outer glumes and the inner glume the 

 rachilla is frequently expanded in an annular thickening. This 

 thickening tends to force the outer glume and palea apart. The 

 extent to which the thickening is developed can be used to 

 distinguish the rices.
