1 A sister plant of '08, 98, and '08, 100, gave a remarkably aberrant result. This was 

 '08, 99 in which there were 182 plants. Of these 180 were fertile and only 2 were sterile. 

 As in the sister plants the coloured were all deep purples and Miss Hunt and there is no 

 reason to suspect any error. This almost complete absence of steriles is quite unlike 

 anything else we have encountered and we are unable to offer any explanation.
