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 ...

Divergent pollination system and morph-dependent effects of corolla length on inaccuracy of reciprocity and reproductive success of a distylous species of Rubiaceae

Acta Botânica Brasílica, 2021
Intraspecific floral variations may affect the degree of generalization and efficacy of pollinators, with consequences for plant reproductive success.

Pollination by hummingbirds of Vriesea gigantea (Bromeliaceae) populations in Southern Brazil

Rodriguésia, 2020
The pollination syndrome hypothesis usually does not successfully apply to the diversity of floral phenotypes or help predict the pollinators of most plant species.

Secondary pollen presentation and foral traits of Heliconia psittacorum

Ornamental Horticulture, 2018
The secondary presentation of pollen consists of a foral mechanism where the presentation of pollen occurs in other foral structures in addition to the anther, in order to increase the precision of the dispersion of the pollen by the vectors.

Is Self‐Pollination Sufficient to Maximise Seed Set and Fruit Quality in Kiwifruit Hermaphrodites?

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
The purpose of this study was to determine whether supplementary pollination of each of two hermaphrodite kiwifruit selections was likely to produce any significant improvement in seed set or fruit quality, compared with self‐pollination alone. Three main pollination treatments were applied to floral shoots: self‐pollination alone and self‐pollination ...

Cordia subcordata (Boraginaceae), a distylous species on oceanic coral islands, is self-compatible and pollinated by a passerine bird [PDF]

Plant Ecology and Evolution, 2020
Background and aims – Distyly is usually rare on oceanic islands, which is probably due to the difficulty for distylous plants to colonize those islands.

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

New Phytologist, Volume 250, Issue 5, Page 3460-3474, June 2026.
Summary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects
