Aggregate enantiostyly: Floral visitor interactions with a previously unreported form of floral display

Journal of Pollination Ecology, 2018
Floral herkogamy, or the spatial separation of reproductive structures, plays an important role in the evolution of plant mating systems. One form of herkogamy is enantiostyly, or the alternate presentation of stigmas to the left and right of the floral ...

Distylous traits in Cordia dodecandra and Cordia sebestena (Boraginaceae) from the Yucatan Peninsula

Botan‪ical Sciences, 2014
Distyly is a genetically-controlled polymorphism with two floral morphs exhibiting spatial, reciprocal separation between stigmas and anthers; one morph has long styles and short stamens and the other short styles and long stamens.

Herkogamy and its effects on mating patterns in Arabidopsis thaliana. [PDF]

, 2013
The evolution of mating systems, which exhibit an extraordinary diversity in flowering plants, is of central interest in plant biology. Herkogamy, the spatial separation of sexual organs within flowers, is a widespread floral mechanism that is thought to

Is there interspecific fruit set in distylous, synchronopatric species of Erythroxylum P. Browne (Erythroxylaceae)? [PDF]

Brazilian Journal of Biology
Sympatric congeneric species that overlap the flowering period and have morphologically similar flowers tend to be pollinated by the same groups of pollinators, facilitating interspecific pollination and hybridization.

Herkogamy, a Principal Functional Trait of Plant Reproductive Biology [PDF]

, 2018
Premise of research. Phenotypic traits that consistently mediate species' responses to environmental variation (functional traits) provide a promising approach toward generalizing ecological and evolutionary patterns and thereby gaining insights into the

Mixed mating in homostylous species: genetic and experimental evidence from an alpine plant with variable herkogamy, Primula halleri [PDF]

, 2018
Premise of research: Self-compatibility is a requirement for reproductive assurance via selfing and may therefore be beneficial in environments with infrequent or unpredictable pollinator service.

Breeding biology and distyly in Palicourea rigida H. B. & K. (Rubiaceae) in the Cerrados of Central Brazil Biologia reprodutiva e distilia em Palicourea rigida H. B. & K. (Rubiaceae) em Cerrados do Brasil Central

Acta Botânica Brasílica, 2010
Distyly is a floral polymorphism more common among the Rubiaceae than in any other angiosperm group. Palicourea rigida is a typically distylous species of the Rubiaceae widely distributed in the Brazilian Cerrados.

Herkogamy in the Plains Pricklypear Cactus Opuntia polyacantha Haw. (Cactaceae: Opuntioideae) [PDF]

, 2022
The spatial separation of anthers and stigmas, also known as herkogamy, is a widespread reproductive strategy in flowering plants. Herkogamy has evolved alongside, or in lieu of, self-incompatibility systems, and functions to limit the rate of self ...
