Some fascinating information by Dr Glenda Vaughton whose research
interests include:
evolution and ecology of plant mating systems
gender strategies in plants
pollination biology and floral evolution
the evolution of selfing from outcrossing

Plants change their sexuality depending on their environment.
Populations growing in dry areas where there isn't an assured lot of
pollinators, whether insects or birds, are different from ones in wet
areas.

There are a few interesting pictures on this website
