With hundreds of thousands of flowers, macadamia can be limited by not getting enough pollen
This study is the first to demonstrate pollen limitation in a mass-flowering tree.

Herbivores can cause dioecious plants to partly swap sex
Rather than inherently being ‘male’ or ‘female’, Mercurialis annua can produce flowers as a plastic response to its environment.
Where Have All The Good Men Gone? Don’t Despair – Make Some Yourself (That’s What Plants Do..)
Observed rates of evolution in the experiment were among the highest yet recorded.
Hybridisation of native and foreign Sorbus trees in the Polish Carpathian mountains
Sorbus is a highly diverse tree genus but is this the result of hybridisation and introgression between native and foreign species?
Do flowers produce scent when they’re not expecting visitors?
The study demonstrates extensive variation in floral scent among populations of a geographically widespread species, Arabis alpina.
Within a mixed species, annuals self-pollinate more than perennials
A smaller stigma-anther separation in annuals seems to indicate a genetic basis for mating system differences.
Variation in reproduction and genetic diversity across seagrass meadows in Western Australia
How do reproductive effort, genetic diversity and mating systems vary across the range of a seagrass population?
Not All Scarlet Pimpernels Arrange Their Sexual Organs the Same Way to Avoid Pollinating Themselves
When there are unsuitable partners around, Lysimachia arvensis, will alter its herkogamy to favour self pollination over outcrossing with the wrong flowers
Flowers evolve to balance the risks and rewards of self-pollination
The longer a plant waits to self-pollinate, the longer it has to attract pollen from outside. But waiting too long can have consequences.
Mating system, ploidy and competition in Capsella species
Evolution of mating system, life history, and photosynthetic physiology in Clarkia
Flower-level developmental plasticity and mating system in Datura
Reductions in herkogamy with flower positions may be expected in environments with either low pollinator abundance or low nutrients.
