Genera

Oxalidaceae, or the wood-sorrels family, is a family of five genera of flowering plants, with the great majority of the 570 species [2] in the genus Oxalis . Members of this family typically have divided leaves, with the leaflets showing "sleep movements", spreading open in light and closing in darkness.

Description

Oxalidaceae can be herbaceous plants, shrubs, and small trees.

Leaves

Oxalidaceae leaves tend to be alternate, and clustered with well-developed petioles. The abaxial (under) side of the leaves can have trichomes (little hairs). Herbaceous plants in this family tend to have their leaves in the form of a rosette [3] .

Some leaves in genera Averrhoa and Biophytum , can be sensitive to both light and touch [3] .

Flowers

Flowers in this family are perfect, meaning they have a calyx, corolla, gynoecium, and androecium. Oxalidaceae tend to come in parts of 5, having five sepals, five petals, and five fused carpels. The petals of Oxalidaceae flowers tend to be free, or just slightly fused at the base, appearing in red, yellow, white, purple to violet, but never blue [3] .

Classification

The genus Averrhoa , of which the starfruit tree is a member, is usually included in this family (e.g. in APG IV), but some botanists place it in a separate family, Averrhoaceae.
