This family has 800 species and 16 genera.This family is well known in the world of ornamentals because of the pansy (Viola tricolor) and the violet (Viola spp). One interesting thing about violets is there ability to 'self'. In late summer, if conditions get bad, the violets can produce buds that never open. This forces the stamen to be very close to the pistil. Thus, the flowers can "self" if it they have to.
Systematics: The Violaceae has flowers that are zygomorphic and sometimes cleistogomous (remain closed). There are 5 distinct sepals and 5 petals. There is often a spur on the lower most petal. The stamens are coherent around the gynoecium and one of the stamen usually goes into the spur for nectar. There is one locule, and 3 carpels on one syncarpus pistil. The ovary is superior. There is a flap on each anther that sticks forward. The androecium is often closely pressed to the pistil.
