Oleaceae (weeds) - olive family
This family contains more than 500 species of evergreen plants, mostly shrubs and trees. Some are climbing vines. The olive tree (Olea europaea) is cultivated in warmer regions, others are important forest trees like ash trees and still others are grown as ornamentals (e.g. lilac and jasmine) or as spices. However, some species are important weeds like several privets from the genus Ligustrum.
Oleaceae have woody stems, typically with leaves which are arranged oppositely and have entire margins. They have many small fragrant flowers, with four sepals, four petals which are usually joined at the base, two stamens and two fused carpels.
