the plot was not examined in detail till after tlowering was 

 almost over, and the colour of" the stig'ma could be determined in 

 only a small number oF plants. 



The third and fourth examples will be treated together. 

 These were red-grained plants picked from white-grained plots, 

 the red-grained plants in both cases being otherwise almost 

 indistinguishable from the remaining white-grained plants in the 

 plots. The first of these (labelled ^l 1) was found in a variety 

 named Aman paddy from Mymensing, and the second (labelled 

 B 15) in a variety named Bankalam from Bogra. These both 

 split in 1912 into red and white-grained plants, otherwise almost 

 indistinguishable except for grain colour, in the proportions given 

 below — 



Besides these lour cases, njuch further evidence has been 

 afforded by a series of Dinajpur varieties started from single 

 plants selected in 1911. The seed of these varieties was collected 

 from Dinajpur, partly from cultivators and partly from the 

 Bazaars, and all were very mixed. In 1911, eighty-six single 

 plants were selected from these Dinajpur plots and these were 

 sown and transplanted separately in 1912 and no fewer than seven, 

 or a percentage of 8 "15, have given rise to a mixture of types. 

 These are described below in detail. 



In the first (labelled D 28), the parent plant had the small 

 outer glumes coloured reddish-brown, and the inner glumes 

 yellow with a dark apex. This in 1912 split into the following- 

 four main types : — 



(1) Outer glumes coloured reddish-brown, inner glumes at tlowering time 



green with red tip, turning yellow with dark tip, stigmas black... 2 noted. 



(2) Ditto with stigmas white ... ... ... ... 6 ,, 



(.3) Taller, more robust plant, outer glumes coloured reddish-brown, inner
