26 HETEEOSTYLED DIMOEPHIO PLANTS. Chap. I. 



Table 7. 



We here see that the long-styled flowers fertilised 

 with pollen from the short-styled yield more capsules, 

 especially good ones (i.e. containing more than one 

 or two seeds), and that these capsules contain a greater 

 proportional weight of seeds than do the flowers of the 

 long-styled when fertilised with pollen from a distinct 

 plant of the same form. So it is with the short-styled 

 flowers, if treated in an analogous manner. Therefore I 

 have called the former method of fertilisation a legiti- 

 mate union, and the latter, as it fails to yield the full 

 complement of capsules and seeds, an illegitimate 

 union. These two kinds of union are graphically re- 

 presented in Fig. 2. 



If we consider the results of the two legitimate 

 unions taken together and the two illegitimate ones, 

 as shown in Table 7, we see that the former com- 

 pared with the latter yielded capsules, whether con- 

 taining many seeds or only a few, in the proportion of 

 77 to 45, or as 100 to 58. But the inferiority of the 

 illegitimate unions is here perhaps too great, for on a 

 subsequent occasion 100 long-styled and short-styled 

 flowers were illegitimately fertilised, and they together 

 yielded 53 capsules : therefore the rate of 77 to 53, or 

 as 100 to 69, is a fairer one than that of 100 to 58.
