Dichogamous plant species--those that temporally separate male
Whether variation in selfing rate among hermaphroditic flowers exists in natural populations of dichogamous sequential bloomers awaits investigation.
Some of the SC ornithophilous species (the gynomonoecious, gynodioecious, and dichogamous species) require at least interflower pollen transfer.
For example, corolla shape or the duration of staminate and pistillate phases in dichogamous flowers, may enhance pollen donation to the detriment of pollen receipt, or vice versa.
Dichogamous systems, however, are less economical than the simultaneous presentation of stamens and pistils, because pollinators must make two visits to fully service each flower.
It is expected, therefore, that dichogamous flowers will have longer lifetimes than homogamous ones, all other things being equal.
