Description

provided by Flora of Zimbabwe
Small trees, shrubs or perennial or annual herbs. Stipules usually 0, but sometimes present and if so, small and gland-like. Leaves alternate (in ours), simple, entire. Sepals 5; two lateral ones often petal-like (wings); two anterior ones sometimes joined. Petals 3-5. Stamens 5-8; filaments usually united in a slit tube. Ovary superior, 1- or 2-locular. Fruit (in ours) a capsule or a samara.

Polygalaceae

provided by wikipedia EN

The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 21 genera and ca. 900 known species[2] of herbs, shrubs and trees. Over half of the species are in one genus, Polygala, the milkworts.

Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the Angiosperm Phylogeny Group, the family belongs in Fabales.
