New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.Genetic variation in three endangered allopolyploid Lepidium species was assayed using amplicon sequencing of 16 nuclear genesand phylogenetic analysis to distinguish ortholog/paralog (homoeolog) relationships. After phylogenetic analysis, the 16 sets of gene sequences were scored as co‐dominant alleles at a total of 55 putative loci in the target ...

Psychotria caraballoensis (Rubiaceae), a new species from northern Luzon, Philippines
Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.In this paper, we describe and illustrate Psychotria caraballoensis, a new endemic species from the Caraballo Mountain Range, Luzon, Philippines. It is allied to the Subalpina species group sensu Sohmer and Davis (2007), and resembles Psychotria sohotonensis.

TAXON, Volume 75, Issue 1, February 2026.Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

bioRxiv, 2018 About 15,000 angiosperm species (∼6%) have separate sexes, a phenomenon known as dioecy. Early work reported a lower species richness in dioecious compared to non-dioecious sister clades, which was taken to suggest that dioecy might be an evolutionary ...

Life‐history trade‐offs promote the evolution of dioecy
Journal of Evolutionary Biology, 2018 Most dioecious plants are perennial and subject to trade‐offs between sexual reproduction and vegetative performance. However, these broader life‐history trade‐offs have not usually been incorporated into theoretical analyses of the evolution of separate

Frontiers in Plant Science, 2019 Sexual dimorphism in vegetative and reproductive traits is associated with contrasting strategies of males and females for response to varied environmental conditions, causing sex-specific reproduction success and consequently long-distance dispersal and

Phylogenetic origins of dioecy in Silene
, 2005 The aim of this project is to provide a phylogenetic/taxonomic framework for the evolution of dioecy within Silene (Caryophyllaceae). There are several dioecious taxa within the genus, traditionally classified in the sections Elisanthe and Otites.

The Evolution of Dioecy-Concluding Remarks
Annals of the Missouri Botanical Garden, 1984 Since the pioneer work of Darwin on the evolution of sexual systems in plants (Darwin, 1877a, 1877b) no sexual strategy in recent years has attracted as much attention as dioecy. First, a number of population genetic models were developed in the 1970s to trace the evolution of dioecy via different pathways (Lloyd, 1975, 1976, 1979; Ross, 1970, 1978 ...

Duodichogamy and androdioecy in the Chinese Phyllanthaceae Bridelia tomentosa [PDF]
, 2007 Flowering plants commonly separate male and female function in time, but rarely are the two stages synchronized within and among individuals. One such temporal mating system is duodichogamy in which each plant produces two batches of male flowers that ...
