365 



Table showing the Average Proportion t)F Failures of Seeds. 

 (See below for explanation.) 



The percentage results given represent the proportion of the average number of 

 ovules, as stated in the second column. 



The data given in the last two columns, A and B, distinguish between the failures of 

 ovules and the failures of young seeds. 



The fruit-type is indicated by the capital letter after the plant-name : B, berry ; C, 

 capsule ; D, drupe ; L, legume ; N, nut.

 examined told its own story, and although many points remain unde- 

 termined, the data obtained go to support the following conclusions.
