PREMISE OF THE STUDY Populations of heterostylous species are characterized by two or three floral morphs with reciprocal positioning of stigmas and anthers. Theoretical models predict equal morph frequencies (isoplethy) when disassortative mating is prevalent in populations, but biased morph ratios may occur when variation in the expression of heterostyly causes deviations from intermorph mating. METHODS We explore the role of sex-organ deployment in governing morph ratios in two closely…

Patterns of variation in distylous traits and reproductive consequences in Erythroxylum species and populations.

Erythroxylum species showed variation in the distylous syndrome, with changes in the incompatibility system that corresponded with deviations from 1:1 morph ratio, and variation in reciprocity that correlated with variation in female reproductive fitness.

High herkogamy but low reciprocity characterises isoplethic populations of Jasminum malabaricum, a species with stigma-height dimorphism.

The presence of stigmaheight dimorphism and estimated morph ratios in four naturally occurring populations of Jasminum malabaricum are investigated, highlighting the importance of sufficient effective pollinators and floral morphological features, particularly herkogamy, in maintaining isoplethy in species with stigma-heightDimorphism.

Increased variation in sex organ positions can increase reciprocity and pollination success in heterostylous plant populations

A reciprocity index is formulated that incorporates variation in sex organ positions among individuals in a population and asked if estimates of reciprocity can predict reproductive success in naturally occurring heterostylous populations, and highlights the importance of incorporating intra-population variation insex organ dimensions in quantifying reciprocity.

Bee-Mediated Selection Favors Floral Sex Specialization in a Heterantherous Species: Strategies to Solve the Pollen Dilemma

The results suggest that bee-mediated selection favors floral sex specialization and stylar dimorphism in M. radula, optimizing reproductive success and solving the pollen dilemma.

Gender specialisation and stigma height dimorphism in Mediterranean Lithodora fruticosa (Boraginaceae)

The results of this study are puzzling in light of recent work that suggests that L. fruticosa has a multi‐allelic self‐incompatibility system, and hypotheses that might explain it are discussed.

What explains the variation in length of stamens and styles in a pollen flower? a study exemplified by Macairea radula (Melastomataceae)

Variations among stamens and styles are widespread in angiosperms. In both heteranthery and heterostyly, variation in styles and stamens is considered an outcome of selective forces driven mainly by

Herkogamy but not reciprocity is a better predictor of legitimate pollen transfer and fruit set in Jasminum malabaricum, a self-compatible species with stigma-height dimorphism

Herkogamy was more important than reciprocity in increasing legitimate pollen transfer and reproductive success in J. malabaricum, and this may allow the evolution of reciprocal arrangement of sex organs at a later stage in the pathway towards distyly.

Inter-morph pollen flow and reproductive success in a self-compatible species with stigma-height dimorphism: the influence of herkogamy and reciprocity.

This study is the first to quantify and report natural inter- morph stigmatic pollen load in a species with stigma-height dimorphism, highlighting the importance of both herkogamy and reciprocity in facilitating inter-morph pollen transfer.

'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.



Reciprocal style polymorphisms are not easily categorised: the case of heterostyly in Lithodora and Glandora (Boraginaceae).

The prediction that flower traits as a whole respond to selective pressure to assure the exact location of pollen on the pollinator body is verified and most reciprocal populations and species, where between-morph pollen transfer is expected to be higher, would show greater integration.

Evolutionary maintenance of stigma-height dimorphism in Narcissus papyraceus (Amaryllidaceae).

Stigma-height dimorphism in N. papyraceus is maintained in populations by insect-mediated cross-pollination with biased morph ratios and stylar monomorphism likely resulting from the combined influence of the inheritance of the polymorphism, morph-specific differences in assortative mating and founder effects.

Morph‐ratio variation, population size and female reproductive success in distylous Pulmonaria officinalis (Boraginaceae)

The results suggest that local morph ratios are influenced both by the relative fecundity of L‐ and S‐morph individuals and by stochastic processes in small populations.

Reproductive consequences of interactions between clonal growth and sexual reproduction in Nymphoides peltata: a distylous aquatic plant.

Experimental pollinations indicate that N. peltata possesses a strong dimorphic incompatibility system preventing self and intramorph fertilizations, and an experiment involving the manipulation of morph ratios in an experimental population and an investigation in a natural population with strong morph substructure both provided evidence that compatible pollen dilution limits fertility.

Disassortative mating prevails in style‐dimorphic Narcissus papyraceus despite low reciprocity and compatibility of morphs

Investigating mating patterns, female fecundity, and siring success of style‐length morphs in Narcissus papyraceus, a self‐incompatible but morph‐compatible species with dimorphic and monomorphic populations in central and north regions of its range, provided evidence for the evolutionary stability of stylar dimorphism in at least some populations.

Frequency–dependent variation in reproductive success in Narcissus: implications for the maintenance of stigma–height dimorphism

Patterns indicate that in the absence of physiological barriers to intra–morph mating, negative frequency–dependent selection contributes to the maintenance of stylar polymorphism through inter–morph pollen transfer.


The influence of historical factors on morph frequencies prior to equilibrium was investigated using a deterministic computer model and indicated that in nonequilibrium populations the short‐styled morph will be in excess and the long‐styles will be underrepresented, suggesting that historical factors play an important role in determining population structure in P. cordata.

Stigma–anther reciprocity, pollinators, and pollen transfer efficiency in populations of heterostylous species of Lithodora and Glandora (Boraginaceae)

Results show a correlation between the degree of reciprocity and the efficiency of pollinators associated with the populations, which suggest that pollinators are a possible selective force driving the evolution of heterostyly.

Pollinator shifts and the loss of style polymorphism in Narcissus papyraceus (Amaryllidaceae)

It is found that with LT pollinators, both morphs were successfully pollinated in all morph ratio conditions, suggesting that these insects could be involved in maintenance of the polymorphism, although other factors may also play a role.

Dimorphisms and self-incompatibility in the distylous species Palicourea demissa (Rubiaceae): possible implications for its reproductive output

Flower attributes and ancillary floral polymorphisms typically associated to heterostylous plants in Palicourea demissa, a distylous shrub of the Venezuelan Andes cloud forests, are described, suggesting a higher reproductive potential among short-styled plants.
