The island syndrome in plants on New Zealand's outlying islands: a review

New Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.
ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.

Domestication During Restoration: Unintentional Selection During Eight Generations of Wild Seed Propagation Reduces Herkogamy, Dichogamy and Heterozygosity in Clarkia pulchella

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Characterization of 24 microsatellite markers in Primula chungensis (Primulaceae), a distylous–homostylous species, using MiSeq sequencing

Plant Diversity, 2016
Primula chungensis is a species with considerable floral and mating-system variation, including distylous (outcrossing), homostylous (selfing) and mixed populations that contain both outcrossing and selfing forms.

Atypical distyly in Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species

Acta Botânica Brasílica, 2013
Distyly is a genetically controlled floral dimorphism, characterized by the reciprocal positioning of pin and thrum morphs, a heteromorphic incompatibility system and a balanced morph ratio (isoplethy).

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Risk of genetic vulnerability and aspects of the reproductive biology of Psychotria ipecacuanha (Rubiaceae), a threatened medicinal plant species of Brazilian forests

Acta Botânica Brasílica
Psychotria ipecacuanha, commonly known as Ipeca, is a medicinal plant of pharmacological and economic value. The species is distylous; it has populations with two floral morphs, one with long and one with short styles.

Rapid detection of RNase‐based self‐incompatibility in Lysimachia monelli (Primulaceae)

American Journal of Botany, Volume 112, Issue 1, January 2025.
Abstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.

The Primula edelbergii S‐locus is an example of a jumping supergene

Molecular Ecology Resources, Volume 24, Issue 6, August 2024.
Abstract Research on supergenes, non‐recombining genomic regions housing tightly linked genes that control complex phenotypes, has recently gained prominence in genomics. Heterostyly, a floral heteromorphism promoting outcrossing in several angiosperm families, is controlled by the S‐locus supergene.

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.
