Perianth symmetry in sexually differentiated flowers of Akebia quinata (Lardizabalaceae) [PDF]

open access: yesPeerJ
Sexual differentiation of monoecious plants usually involves differentiation in the size of female and male flowers produced on the same individuals. In the nectarless Akebia quinata (Houtt.) Decne (Lardizabalaceae), the trimeric, actinomorphic female ...

The consequences of monoecy and dioecy in congeneric species, and their implications for the evolution of dioecy in the genus Viscum [PDF]

open access: green, 2015
Two species of Viscum, the dioecious Viscum capense ssp capense and the monoecious Viscum rotundifolium , were compared in terms of their ecology, repioductive biology and genetics in order to determine some potential selective advantages of dioecy in ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna [PDF]

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Widespread male sterility and trioecy in androdioecious Mercurialis annua: Its distribution, genetic basis, and estimates of morph‐specific fitness components [PDF]

open access: yesAmerican Journal of Botany, Volume 111, Issue 11, November 2024.
Abstract Premise Angiosperms range in sexual system from hermaphroditism through gynodioecy and androdioecy to dioecy. Trioecy, where females and males coexist with hermaphrodites, is rare. Recently, trioecy was documented in hexaploid populations of the wind‐pollinated herb Mercurialis annua in Spain.

Spatial Patterns and Drivers of Angiosperm Sexual Systems in China Differ Between Woody and Herbaceous Species [PDF]

open access: yesFrontiers in Plant Science, 2020
Plant sexual systems play an important role in the evolution of angiosperm diversity. However, large-scale patterns in the frequencies of sexual systems (i.e. dioecy, monoecy, and hermaphroditism) and their drivers for species with different growth forms

Monoicy, dioicy, and genetic structure in three species of Sheathia (Batrachospermales, Rhodophyta) [PDF]

open access: yesJournal of Phycology, Volume 61, Issue 4, Page 820-839, August 2025.
Abstract Sexual systems (i.e., separate vs. combined sexes) vary widely among eukaryotes and influence the evolution of reproductive systems, which shape genetic structure and evolutionary trajectories. In diploid‐dominant angiosperms, combined (i.e., hermaphroditism) and separate sexes are expected to correlate with selfing and outcrossing ...

Patterns and drivers of plant sexual systems in the dry-hot valley region of southwestern China [PDF]

open access: yesPlant Diversity
Sexual systems play important roles in angiosperm evolution and exhibit substantial variations among different floras. Thus, studying their evolution in a whole flora is crucial for understanding the formation and maintenance of plant biodiversity and ...

Hybridization, polyploidy, and evolutionary transitions between monoecy and dioecy in Bryonia (Cucurbitaceae) [PDF]

open access: closed, 2008
Correns’s 1903 (Berichte der Deutschen Botanischen Gesellschaft 21: 133 – 147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the first instance of an XY sex determination ...

Monoecy, anemophily, anemochory and regeneration ecology of Hildegardia populifolia (Roxb.) Schott. and Endl. (Malvaceae), an economically important endemic and endangered dry deciduous tree species of southern Eastern Ghats, India

open access: goldJournal of Threatened Taxa, 2014
Hildegardia populifolia is a critically endangered tree species. All phenological events—leaf flushing, shedding, flowering, fruit dispersal occur one after the other during the dry season.
