A small, disparate family of herbs and trees in which the leaves are large, palmately nerved, and without stipules. The flowers are unisexual, the ovary inferior, and placentation parietal. The fruit is a capsule, with many seeds. The family is perhaps related to the Begoniaceae and Cucurbitaceae. There are 3 genera, with 4 species: Datisca species, herbs of America and Asia, and Octomeles sumatrana and Tetrameles nudiflora, trees of Indo-Malaysia.
