Author remarks on the appearance of different col our - 

 varieties under cultivation. He contrasts some cases 

 (Primula acaulis, P. sinensis) where blue varieties have 

 arisen, with other cases (Althaea, Antirrhinum, Calceolaria, 

 among others) where no blue variety has appeared. Some- 

 times variation only gives rise to different shades of the 

 original colour.

 of these, one varied like the original parent. This variation 

 to redness appeared to be affected by weather conditions. p. 157
