Rather than inherently being 'male' or 'female', Mercurialis annua can produce flowers as a plastic response to its environment.

Trade-offs among growth, reproduction and defence in dioecious juniper
Can variation in the essential oil yield of juniper be explained by a trade off between growth, defence and reproduction?

Tropical islands lead to more diversity in Palm sexual reproduction
Isolation and sexual adaptability contributed to the evolution of thousands of palm species.

Males become female when striped maples take a health hit
Above a certain trauma threshold, male trees had a high probability of becoming female, possibly in a bid to better their chances at reproduction.

Are males and females produced in equal proportions in the sexually cryptic coco de mer?
Morgan et al. explores sex ratios in populations of Lodoicea maldivica in the Seychelles.
Patterns of sex expression, health and mortality in a sex-changing tree
The ability of individuals to change sex during their lifetime is known as environmental sex determination (ESD). This ability represents a unique life history trait, allowing plants to allocate resources differentially...

Breeding system evolution in Ficus and Moraceae
Diverse breeding systems have evolved in angiosperms from the bisexual flowers of their last common ancestor. However, breeding system evolution remains poorly understood in many plant families, including the Moraceae...
Sexual dimorphism and rapid turnover in gene expression in pre-reproductive seedlings of a dioecious herb
Sexual dimorphism in morphology, physiology or life history traits is common in dioecious plants at reproductive maturity, but it is typically inconspicuous or absent in juveniles. Although plants of different sexes...
Positive and negative interactions on a dioecious grass species performance
Dioecious plants are of particular concern in view of global environmental changes because reproductive females are more sensitive to abiotic stresses, thus compromising population viability. Positive interactions with...
Limited seed and pollen gene dispersal in Taxus baccata
Dispersal is crucial due to its direct impact on dynamics of a species’ distribution as well as having a role in shaping adaptive potential through gene flow. In plants forming scarce and small populations, knowledge...
Sex-specific functional traits in cycads
The Mesozoic is often referred to as the “age of cycads”. During this period, dinosaurs roamed vast cycad forests, yet modern cycads are a vestige of their Mesozoic glory. Extant species represent the oldest lineage of...

Amborella trichopoda helps reveal features of the first flowering plants
It's difficult to peer into the past to see the first flowering plant, but Charlie Scutt shows how an ancestor in the modern-era provides some clues as to what it looked like.

Genetic sex determination and sexual instability in Amborella trichopoda
Amborella trichopoda, the sister species of all other extant angiosperms, is typically dioecious, producing male and female flowers on separate individuals. Anger et al. map sex phenotypes onto a phylogeny of basally...

High male fertility in males of a subdioecious shrub
Female reproductive success in females versus hermaphrodites has been well documented. However, documenting a potential advantage in fertility of male versus hermaphrodite individuals in subdioecious species is also...
