Today we will meet the Violet family - Violaceae. The family includes 25 genera and 1000 species of flowering herbs, lianas, shrubs and trees. The family derives its name from the genus Viola of violets and pansies. It is the largest genus in the family with around 400 species.
The family members occur mostly in the tropical and warm temperate regions although there are only few species found in this region.
Some of the characteristics of Violaceae plants include:
ЁЯНВ: The leaves are usually simple (some species may have palmate or deeply dissected leaves) have stipules and are arranged alternately (sometimes opposite). Leaves often have toothed or lobed margins.
ЁЯМ╖The flowers are usually bisexual and zygomorphic (sometimes actinomorphic), with five free petals which may be blue, purple, yellow, or white in color. Stamens 5 in number often joined into a ring around the ovary and style. The
ovary is superior with an unlobed or beak-shaped stigma.
ЁЯНТ The fruit is usually a small, dry capsule or berry that contains many seeds.
