PREMISE OF THE STUDY Variation in the mating system of hermaphroditic plant populations is determined by interactions between genetic and environmental factors operating via both pre- and postmating processes. Models predicting the maintenance of intermediate outcrossing rates in animal-pollinated plants often assume that the mating system is primarily controlled by floral morphology and pollinator availability, but rarely has the influence of postpollination processes on variation in…

Effects of pollination and postpollination processes on selfing rate in Mimulus ringens.
Selfing rate in Mimulus ringens is influenced by small differences in the timing of pollen arrival, but not by nonrandom postpollination sorting.
Selfing rates vary with floral display, pollinator visitation and plant density in natural populations of Mimulus ringens
It is suggested that pollinator visitation and floral display, two factors that interact to affect geitonogamous pollinator movements, can influence the selfing rate.
Mating pattern of a distylous primrose in a natural population: unilateral outcrossing and asymmetric selfing between sexual morphs
A mathematical model of the overdominance hypothesis is built to confirm that it is logically sound and is consistent with the explanation that distyly in this species is maintained either by overDominance due to previously reported recessive lethal effects of the thrum allele or by effectively dioecious mating if inbreeding depression is strong.
Outcrossing rates in a rare “ornithophilous” aloe are correlated with bee visitation
The contribution of bees to outcrossing rates and inbreeding in the rare self-compatible treelet Aloe thraskii is compared and the contribution of insect pollinators can make to out Crossing rates of rare plant species that are seemingly adapted for bird pollination is highlighted.
Relatively weak inbreeding depression in selfing but also in outcrossing populations of North American Arabidopsis lyrata
Estimates of inbreeding depression in the North American herb Arabidopsis lyrata were clearly lower than previous estimates based on the same performance traits in outcrossing European populations of A. lyrata, which may help explain why selfing could evolve in North American A. lyricata.

Here, links between sexual selection, evolution of selfing, and speciation are synthesized, with particular focus on identifying commonalities and differences between plant and animal systems and pointing to areas warranting further synergy.
'A most complex marriage arrangement': recent advances on heterostyly and unresolved questions.
Ecological, phylogenetic and molecular genetic data have validated some features of theoretical models on the selection of the polymorphism, and heterostyly is the best-understood floral polymorphism in angiosperms, many unanswered questions remain.
Optimal inaccuracy: estimating male fitness in the movement-assisted dichogamous species Clerodendrum infortunatum
These questions are addressed in Clerodendrum infortunatum, a protandrous, movement-assisted dichogamous species, and predictions from optimality arguments are made by measuring sporophyll angles over time, by experimentally manipulating flowers, and by estimating correlates of the resultant fitness.
An Unexplored Side of Regeneration Niche: Seed Quantity and Quality Are Determined by the Effect of Temperature on Pollen Performance
Pre-fertilization stages of seed production, particularly the extreme sensitivity of male gametophyte performance to temperature, are the key determinants of a species’ regeneration niche, and it is suggested that previous views stating that the regeneration niche begins with the production of seeds should be modified to include the preceding stages.
Pollen--tiny and ephemeral but not forgotten: New ideas on their ecology and evolution.
There is a tremendous diversity of interests that touch on pollen performance, ranging from the ecological setting on the stigma, structural and physiological aspects of pollen germination and tube growth, the form of pollen competition and its role in sexual selection in plants, virus transmission, mating system evolution, and inbreeding depression.

The results from experiments with marker genes and floral manipulations provide evidence for the function of herkogamy and dichogamy in reducing self-pollination and promoting pollen dispersal and evidence is presented indicating that increased selfing resulting from changes to floral design, or geitonogsamy in large clones, can act as a stimulus for the evolution of dioecy.

The ability to produce mostly outcrossed progeny when pollinators are abundant, but to reliably produce seed under a variety of environmental and demographic conditions may be favored in E. paniculata because of its colonizing life history and occurrence in ephemeral habitats.
Mass-Action Models of Plant Mating Systems: The Evolutionary Stability of Mixed Mating Systems
The results suggest that the probability of successful outcrossed reproduction plays at least as important a role in determining the mating system of plants as inbreeding depression.
Variation in Outcrossing Rates in Eichhornia paniculata: Temporal Changes in Populations of Contrasting Style Morph Structure
The significance of temporal variation in outcrossing frequency in plant populations is discussed in relation to its effect on population genetic structure and recent models of mating-system evolution.
Dichogamy correlates with outcrossing rate and defines the selfing syndrome in the mixed-mating genus Collinsia.
Assessment of the variation in the pollination environment, which can increase selfing rates in more 'outcrossing' species but can also decrease selfing rate in more '[selfing] species, is critical to understanding mating system evolution of SC MM taxa".
Heterostyly promotes disassortative pollination and reduces sexual interference in Darwin's primroses: evidence from experimental studies
The results help to understand how the morphological and physiological components of heterostyly contribute to optimizing pollen transfer and minimizing self- and intra-morph pollination, thus promoting more efficient outcrossing in species with this floral polymorphism.
The Evolutionary Enigma of Mixed Mating Systems in Plants: Occurrence, Theoretical Explanations, and Empirical Evidence
▪ Abstract Mixed mating, in which hermaphrodite plant species reproduce by both self- and cross-fertilization, presents a challenging problem for evolutionary biologists. Theory suggests that
Reproductive assurance varies with flower size in Collinsia parviflora (Scrophulariaceae).
This paper documents significant among-population variation in flower size in Collinsia parviflora and shows that pollinators preferred large flowers over small flowers in experimental arrays, the first experimental evidence showing a trait-dependent RA benefit of selfing under natural pollination conditions.

Experimental manipulation of the morph structure of garden populations of self‐compatible, tristylous Eichhornia paniculata suggests that the selective basis for the establishment of floral polymorphism could have been increased pollen transfer rather than higher levels of outcrossing.
