The concept of sexual selection (intrasexual competition for mates and mate preference) is used in revising the classical explanation of dioecy in plants. Male and female functions of hermaphroditic flowers can be subject to different sexual selection pressures, which may conceivably lead to the separation of male and female structures. This suggestion does not exclude genetic advantages that may accrue from outcrossing; the two aspects of selection probably operated together in the evolution… 
Sexual selection in a hermaphroditic plant
TLDR
It is reported that a suite of floral traits of a hermaphroditic plant is best interpreted as having evolved through the male competition component of sexual selection, a result with important implications for evolutionary studies of pollination systems.
Sexual Selection in Angiosperms: Paradox Re-visited
TLDR
The present chapter discusses how sexual selection can occur in plants even though individuals do not make a direct interaction and attempts to review the conceptual developments in plants using evidences from different fields.
The evolution of gender-biased nectar production in hermaphroditic plants
The evolution of secondary sexual floral traits may be driven by selection through male or female reproductive success. Even so, the gender-biased function of a floral trait is often unapparent
MODELS OF SEXUAL SELECTION IN HERMAPHRODITES
Ideas deriving from sexual selection theory frequently motivate investigation of reproductive traits in hermaphroditic species, but theorists often couch sexual selection in terms of organisms with
Models of Sexual Selection in Hermaphrodites, Especially Plants
TLDR
How theoretical (especially quantitative genetic) models of sexual selection in hermaphrodites differ from those in species with separate sexes is investigated.
Sexual selection, sexual dimorphism and plant phylogeny
TLDR
It is suggested that the similarity of pattern may be accounted for by a similarity of process within the angiosperms and, indeed, to angiosperm radiation.
THE EFFECT OF INVESTMENT IN ATTRACTIVE STRUCTURES ON ALLOCATION TO MALE AND FEMALE FUNCTIONS IN PLANTS
TLDR
It is shown that the spread of females is unlikely, unless there is high inbreeding depression and a rather high selfing rate, and that in some circumstances a linear relation between number of fertilized ovules and number of seeds matured can be less favorable for the invasion of females than is a highly concave relation.
Sexual Selection in Plants: Perspective and Overview
TLDR
It is argued that sexual selection can occur at any phase of the reproductive process, from "courtship" to postnatal stages, in plants as well as animals.
Conflicting selection pressures on reproductive functions and speciation in plants
TLDR
It is believed that selection pressures generated by sexual conflict need to be appreciated in order to fully understand microevolutionary processes which may lead to genetic divergence and speciation in plants.
Sources of Variation in Plant Reproductive Success and Implications for Concepts of Sexual Selection
TLDR
An experimental protocol designed to yield more information on nonrandom transmission in general and on sexual selection as a special case is presented and an emphasis is primarily on identifying genetic sources of variance.

The possible advantages to a species of internal rather than external fertilization have frequently been stressed, though one important point appears persistently to have escaped comment. In terms of

TLDR
It is suggested the pollen removal by small bees that forage on Heracleum in but not outside the woods may be the selective force that accounts for the larger percentage of male flowers of woods plants.

An optimality model based on the tradeoffs between seed set efficiency and outbreeding is presented that predicts under what conditions selfing should be favored over outcrossing. The model predicts
MAINTENANCE OF MALES AND FEMALES IN HERMAPHRODITE POPULATIONS AND THE EVOLUTION OF DIOECY
TLDR
Darwin (1877) studied unisexuality in plants and considered its possible functions and evolution, and Mather (1940) and Lewis (1942) considered that gynodioecY was superior to dioecy since the degree of outbreeding could vary, and Lewis held also that gynaecy was probably not an intermediate step in the evolution of dioECy.
The Influence of Habitats on Mating Systems of North American Passerine Birds
TLDR
Regardless of sex ratio, a polygynous mating is expected to be adaptive for the females as well as for the male, and marshes and prairies are more likely than forests to present the minimum requisite food supply and sufficiently great differences in available food between territories for selection to favor polygyny.

A Model for the Evolution of Dioecy and Gynodioecy
TLDR
The equilibria generated by the model agree closely with the results of genetical studies of those dioecious species with male-determining Y chromosomes that have been investigated, in which both male-and female-sterility factors have been found, showing complementary dominance relations and no crossing-over between the loci.

TLDR
The reproductive biology of a monoecious species, Cupania guatemalensis Radlk, a small tree found in lowland tropical forests of Central America, is described and the pattern of spatial and temporal variation in the relative frequencies of staminate and pistillate flowers at the individual and population levels is examined.
