, 1992 Since heterostyly became well known over a century ago, botanists have consistently proposed that its adaptive significance lies in the encouragement it provides for outcrossing. Darwin (1877, p. 258) for example, wrote that “We may feel sure that plants have been rendered heterostyled to ensure cross-fertilization, for we know that a cross between the

Heterostyly in the Canarian endemic Jasminum odoratissimum (Oleaceae)
Nordic Journal of Botany, 2003 Jasminum odoratissimum is a Madeira and Canary Islands endemic showing classic heterostyly, i.e. with long‐styled flowers with anthers at a low level in the corolla tube and short‐styled flowers with anthers at a high level in the corolla tube. Short‐styled flowers have large pollen, whereas long‐styled flowers have small pollen.

, 1992 Breeding experiments on the genetics of heterostyly began in the 19th century led by Hildebrand (1866) and by Darwin (1877), before Mendel’s work was rediscovered in 1900. Bateson and Gregory (1905) introduced their paper on the inheritance of heterostylism in Primula with the statement: “In view of the results obtained by Darwin, Hildebrand and others,

The Development of Heterostyly
, 1992 Heterostyly is a genetic polymorphism in which the two (distyly) or three (tristyly) mating types in a population differ in floral morphology. The principal feature that distinguishes the floral morphs is that they differ in stigma and anther heights. The sex organs are reciprocally positioned with anthers in flowers of one morph at the same level as ...

Heterostyly and the possibility of its breakdown by polyploidization
Plant Species Biology, 2012Abstract Heterostyly is a genetically controlled sexual polymorphism promoting outcrossing by animal pollinators. The occurrence of heterostyly in angiosperms was investigated, and 199 genera in 28 families in 15 orders were recognized as taxa that contain heterostylous species.

Historical Perspectives on Heterostyly
, 1992 Heterostyly was recognized as a morphological feature of certain groups of flowering plants as early as the 16th century, when it was reputedly noted in Primula by Clusius (van Dijk 1943). Few, if any, attempts were made to interpret the adaptive significance of this floral heteromorphism until Charles Darwin and Friedrich Hildebrand studied the ...

Heterostyly and pollinators in Plumbago auriculata (Plumbaginaceae)
South African Journal of Botany, 2009 Plants with hermaphrodite flowers risk conflict between male and female sexual function due to close proximity of sexual organs. Heterostyly, a genetic floral polymorphism characterized mainly by reciprocal herkogamy, may reduce this sexual conflict by ...

Heterostyly accelerates diversification via reduced extinction in primroses [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 The exceptional species diversity of flowering plants, exceeding that of their sister group more than 250-fold, is especially evident in floral innovations, interactions with pollinators and sexual systems.
