have been acquired by a species before those which prevent self-fertilisation; as it would manifestly be injurious to a plant that its stigma should fail to receive its own pollen, unless it had already become well adapted for receiving pollen from another individual. 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
