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.

Are ants a benefit or a detriment when they occupy a plant? New research says they may be both.
Research in two new papers shows how ants can interfere with pollination, but this interference is complicated.
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
Accurate position exchange of stamen and stigma resolves the herkogamy dilemma in a protandrous plant, Ajuga decumbens (Labiatae)
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.
Herkogamy and dichogamy in style dimorphic flowers of Narcissus broussonetii (Amaryllidaceae)
Outbreeding and inbreeding strategies in plant communities of the Venezuelan Gran Sabana Plateau
Ramírez and Hokche evaluated the breeding system, sexual system, dichogamy and herkogamy of herbaceous-shrubby communities from the Gran Sabana Plateau, Venezuela

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.
Hawkmoth pollination syndrome and adaptive floral integration
In the right place at the right time for pollination
Parnassia epunctulata, a herb with generalized pollination, which exhibits sequential stamen movement.
Floral longevity and autonomous selfing in Collinsia
Under drought stress, cross-pollination early in floral lifespan of Collinsia reduces floral longevity, but excess soil moisture does not extend longevity.
