crossing two plants. The number of seeds thus obtained is much 

 greater and their fertility higher than if S 2 or Sj be fertilised from A 3 , 

 or any other such union be made. Fertilisation of a stigma by sta. 

 of corresponding length Darwin terms legitimate, by sta. of a different 

 length illegitimate. The offspring of illegitimate fert. are few, and 

 have the sterility and other sexual characters of hybrids. As in nearly 

 all other heterostyled pi., the longer the sta. the larger the pollen 

 grains, and the longer the style the larger the papillae of the stigma.
