|The Oxalidaceae are herbs, shrubs, or rarely trees comprising 7 or 8 genera and about 800 species. The leaves are alternate and pinnately or palmately compound or rarely simple by suppression of leaflets; stipules are absent. The flowers are bisexual and actinomorphic. The perianth consists of a calyx of 5 distinct sepals and a corolla of 5 distinct or sometimes basally connate petals. The stamens are basally connate and obdiplostemonous, that is, of two series with the outer series opposite the petals; occasionally 5 stamens are reduced to staminodes. The gynoecium consists of a single compound pistil of 5 carpels, 5 distinct styles, and a superior ovary with 5 locules, each containing one or more axile ovules. The fruit is a loculicidal, sometimes explosively dehiscent capsule or berry.
