Some It should also be observed that many plants still possess a high power of self-fertilisation, although their flowers are excellently constructed for cross-fertilisation; for instance, those of many papilionaceous species.

It may be admitted as almost certain that some structures, such as a narrow elongated nectary, or a long tubular corolla, have been developed in

was a tree bearing numerous hermaphrodite flowers would rarely intercross with another tree unless pollen from a distinct individual were was prepotent over the plants own pollen. Now the separation of the sexes, whether the plant be were anemophilous are entomophilous, would most effectually bar the inter-crossing self-fertilisation, and this may be the cause of so many trees and bushes being diclinous. Or to put the case in another way, a plant would be better fitted for development into a tree, if the sexes were separated, than if it were hermaphrodite; for in the former
