A taxonomic revision of Globba subsect. Nudae (Zingiberaceae)

European Journal of Taxonomy, 2019
Globba subsect. Nudae K.Larsen is revised. Seven species are recognised and three names are lectotypified. A key to the species and descriptions are provided. Three new species are described and illustrated: G. aranyaniae Sangvir. & M.F.Newman sp.

Floral biology of Cneorum tricoccon L. (Cneoraceae): an unknown case of andromonoecy

Collectanea Botanica, 1997
La condició d'andromonoècia ha estat descrita per a una població natural de Cneorum tricoccon L. (Cneoraceae) provinent de Mallorca. Hom ha trobat que la relació entre flors perfectes y flors estaminals varia al llarg de cicles reproductors consecutius ...

Preliminary studies on ornithophilous floral visitors in the Australian endemic Passiflora herbertiana Ker Gawl. (Passifloraceae)

Journal of Pollination Ecology, 2015
The pollination biology of the Australian endemic species Passiflora herbertiana (Passiflora subgenus Decaloba, supersection Disemma, section Disemma) was investigated in a single population growing in the Witches Falls section of Mount Tamborine ...

Sexual Dimorphism in the Andromonoecious Euphorbia nicaeensis: Effects of Gender and Inflorescence Development [PDF]

Annals of Botany, 2008
In andromonoecious taxa with separate floral types along the inflorescence, architectural or plastic effects can simulate floral sexual dimorphism. Both the primary and secondary sexual characteristics of the cyathia of the protogynous andromonoecious species Euphorbia nicaeensis were analysed according to their sex and arrangement on the inflorescence.

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

The M Locus and Ethylene-Controlled Sex Determination in Andromonoecious Cucumber Plants [PDF]

Plant and Cell Physiology, 2001
Sex determination in cucumber (Cucumis sativus L.) plants is genetically controlled by the F and M loci. These loci interact to produce three different sexual phenotypes: gynoecious (M-F-), monoecious (M-ff), and andromonoecious (mmff). Gynoecious cucumber plants produce more ethylene than do monoecious plants.

Sequencing of Complete Chloroplast Genomes and Comparative Analyses of Codon Usage Bias and Phylogeny in Globba Species

Ecology and Evolution, Volume 16, Issue 4, April 2026.
ABSTRACT The genus Globba (Zingiberaceae) comprises over 100 species distributed worldwide, with a primary concentration in Southeast Asia. These plants are of significant interest due to their distinctive and delicate floral morphology as well as their potential medicinal value.

Repeated fractionation and umbel receptacle elongation explain the apparent “panicle with simple umbels” in Ferula species (Apiaceae)

Frontiers in Ecology and Evolution
IntroductionThe carrot family (Apiaceae) is characterized by umbels with umbellets. Traditionally, these umbels are interpreted as inflorescences. Ontogenetic studies, however, indicate that they do not originate from inflorescence meristems but from ...

GENETIC INTERRELATIONS OF TWO ANDROMONOECIOUS TYPES OF MAIZE, DWARF AND ANTHER EAR [PDF]

Genetics, 1922
Attention was called by Montgomery (1906)to the occasional appearance of perfect flowers in the staminate inflorescence of maize and similar cases were reported by Kempton (1913). Montgomery (1911) described with illustrations a true-breeding type of semi-dwarf dent maize, the ears of which were perfect-flowered.

Phenological selection mosaic of predispersal seed predation affects gender variation in an andromonoecious plant

Journal of Ecology, Volume 113, Issue 10, Page 2832-2845, October 2025.
Spatiotemporal variation in seed predation can act as a selective force on floral gender. The floral sex allocation of an alpine andromonoecious herb varied among local populations. Early‐flowering populations suffered from intensive seed predation by moth larvae, where male‐biased sex allocation was advantageous in reducing the risk of oviposition. In
