HETBEOSTYLBD DIMORPHIC PLANTS. Chap. I. 



lication of his paper H. Miiller has made much fuller 

 experiments, and I give his results in the following 

 table, drawn up in accordance with my usual plan : — 



Table 13. 

 Bottonia palustris (from E. Muller). 



The most remarkable point in this table is> the 

 small average number of seeds from the short-styled 

 flowers when illegitimately fertilised, and the unusually 

 large average number of seeds yielded by the illegiti- 

 mately fertilised long-styled flowers, relatively in both 

 cases to the product of the legitimately fertilised 

 flowers.* The two legitimate unions compared with 



* H. Miiller says ('Die Be- 

 fruchtimg,' &c., p. 352) that the 

 long-atyled flowers, when illegiti- 

 mately fertilised, yield as many 

 seeds as when legitimately fer- 

 tilised; but by adding np the 

 number of seeds from all the cap- 

 sides produced by the two methods 

 of feitilisation, as given by him. 



I arrive at the results shown in 

 Table 13. The average number 

 in the long-atyled capstiles, when 

 legitimately fertilised, is 91-4, 

 and when illegitimately fertilised, 

 77 • 5 ; or as 100 to 85. H. Muller 

 agrees with me that this is the 

 proper manner of viewing the 

 case.
