Trees, shrubs or vines with aethereal oil cells, that may lyse into mucilaginous cavities, and (Gyrocarpus and Sparattanthelium only) with cystoliths in leaves and axis. Leaves alternate, petiolate, exstipulate, the blade entire to palmately lobed, or palmately compound, and pinnately, palmately or pedately veined. Flowers epigynous, more or less regular, in thyrsoid or dichasial inflorescences, perfect or unisexual, in the latter case the plants polygamous or monoecious, rarely dioecious; bracteoles present or not; tepals in two whorls of 3–4 (−6), or in one whorl of 4–8, imbricate or valvate; stamens a single whorl of 3–5 (−7); filaments mostly dorsally or at the base provided with a pair of nectariferous glands; anthers 2-locular, dehiscing by valves; ovary inferior, the single carpel with a short or elongate style and a terminal stigma; ovule solitary, pendulous, bitegmic and crassinucellar. Fruit one-seeded, dry, often with lateral or apical wings; seeds without endosperm, dicotyledonous.
