Two floral forms in the same species—distyly
Planta, 2023This paper reviews the progress of research on the morphology, physiology and molecular biology of distyly in plants. It will help to elucidate the mysteries of distyly in plants. Distyly is a unique representative type of heterostyly in plants, primarily characterized by the presence of long style and short style within the flowers of the same species.

THE EVOLUTION OF DISTYLY: POLLEN TRANSFER IN ARTIFICIAL FLOWERS [PDF]
Evolution; International Journal of Organic Evolution, 1994 A recent model by Lloyd and Webb derives conditions necessary for the evolution of distyly based on pollen-transfer probabilities between ancestral morphs and invading mutants. We used bumblebees visiting artificial flowers to measure the parameters of the model. Our findings supported the first evolutionary step proposed by the model, establishment of

Variation and evolution of herkogamy in Exochaenium (Gentianaceae): implications for the evolution of distyly [PDF]
Annals of Botany, 2013 The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt. Little is known about the evolutionary relationships among the three main forms of herkogamy - approach, reverse and reciprocal herkogamy (distyly) - or about transitions to and ...

A Model for the Evolution of Distyly
The American Naturalist, 1979Reasons are given for believing that morphological distyly is unlikely to evolve before the incompatibility system. The first problem studied is therefore the evolution of incompatibility of the type found in distyly, with two pollen and two stigma types.

The Maintenance and Breakdown of Distyly
The American Naturalist, 1979In this paper we present a study of the equilibrium resulting from the balance between recombination and selection against the recombinant phenotypes. The model described in our previous paper, for the phenotypic effects of the character differences involved in heterostyly, is used as a basis for this study.

Distyly and pollen dimorphism in Damnacanthus (Rubiaceae)
Journal of Plant Research, 2003We document distyly in Damnacanthus (Rubiaceae) and investigate pollen morphology in the genus. Within nine taxa in Japan (four species, four varieties and one form), five show distyly. Non-distylous taxa of Damnacanthus always have a long style and short stamens. We examined the pollen morphology of all taxa of Damnacanthus in Japan. The pollen grains

The evolution of distyly in Primula vulgaris
Biological Journal of the Linnean Society, 1986Experiments on pollen flow and seed production were performed in populations of P. vulgaris in order to examine the roles of selection for reduced self-pollination in a partially self-fertile morph, selection for reduced stigma clogging, selection for a pollen saving effect, and selection for disassortative pollination in the evolution of morphological
