Type of the family:— Kewa Christenh. , gen. nov. These are annual or perennial herbs that can be slightly woody. Their leaves are alternate or in false whorls, usually more or less fasciculate at the stem tips, succulent, linear and terete. Stipules are present and fused to the base of the blade, sheathing the stem to different degrees. Inflorescences are terminal or apparently axillary, long-stalked (false) umbels. Flowers are bisexual and actinomorphic and have a whorl of five free sepals, of which three or four become petal-like (usually white or pink), but true petals are absent. The five to 15 (rarely fewer) stamens have shortly fused filaments and dorsifixed anthers opening by longitudinal slits. The superior ovary is composed of three to five fused carpels and is topped by short, fleshy stigmatic crests. The fruit is a membranaceous capsule that opens loculicidally. The family includes the single genus Kewa .
