 Mitchdla repens. 



It follows from this table that 88 per cent, of the 

 paired flowers of both forms, when legitimately fer- 

 tilised, yielded double berries, nineteen of which con- 

 tained on an average 4*4 seeds, with a maximum in 

 one of 8 seeds. Of the illegitimately fertilised paired 

 flowers only 18 per cent, yielded berries, six of which 

 contained on an average only 2'1 seeds, with a maxi- 

 mum in one of 4 seeds. Thus the two legitimate 

 unions are more fertile than the two illegitimate, 

 according to the proportion of flowers which yielded 

 berries, in the ratio of 100 to 20 ; and according to 

 the average number of contained seeds as 100 to 47. 



Three long-styled and three short-styled plants were 

 protected under separate nets, and they produced alto- 

 gether only 8 berries, containing on an average only
