The Theaceae are trees or shrubs comprising about 40 genera and 600 species. The leaves are alternate, simple, and estipulate. The flowers are actinomorphic and are bisexual or rarely unisexual. The perianth consists of distinct or basally connate segments differentiated into usually 5 imbricate sepals and 5 petals. The androecium consists of numerous stamens that are distinct or basally monadelphous, or in 5 fascicles that are opposite and adnate to the petals. The gynoecium consists of a single compound pistil of 3-5 carpels, an equal number of styles, style-branches, or stigmas, and a superior ovary with 3-5 locules containing 2-many axile ovules. The fruit is usually a loculicidal capsule.
