Heterostylous genetic polymorphisms provide paradigmatic systems for investigating
adaptation and natural selection. Populations are usually comprised of two (distyly) or three …

Abstract The ca. 12,000 islands and islets that encompass the Mediterranean Basin
represent a biodiversity hotspot. They have been disconnected from each other and from the …

Premise Distylous species possess two floral morphs with reciprocal positioning of stigmas
and anthers that is hypothesized to promote disassortative pollination. Theoretical models …

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 …

Inter‐morph pollen transfer and its dependence on herkogamy and reciprocity are not
completely understood in species with stigma‐height dimorphism. We asked whether total …

Heterostyly is a polymorphism of reproductive structures, which can manifest as distyly or
tristyly, depending on whether there are two or three floral morphs in the population. Such …

Heterostyly is a polymorphism in which populations comprise two (distyly) or three (tristyly)
floral morphs with reciprocal positioning of the height of the anthers and stigmas (reciprocal …

Animal-pollinated plants show a broad variation in floral morphology traits and gametophyte
production within populations. Thus, floral traits related to plant reproduction and sexuality …

The floral phenotype plays a main role in the attraction and fit of pollinators. Both perianth
traits and the positioning of sex organs can be subjected to natural selection and determine …

Studies of floral polymorphisms have focused on heterostyly, while stigma‐height
dimorphism has received considerably less attention. Few studies have examined the …
