Leaves persistent, alternate and spiral; stipules absent; petiole not differentiated proximally and no part of it persistent, nectar glands glands conspicuous to inconspicuous, at junction of petiole and blade base; blade leathery, venation brochidodromous, apex often acuminate to acute, occasionally obtuse, rarely rounded-mucronate; pit-domatia conspicuous, at junction of abaxial veins with midvein. Inflorescences terminal and axillary, racemes or panicles of spherical or oblong heads, sometimes lateral ones reduced to single head; bracteoles absent. Flowers inconspicuous, each in axil of a bract, unisexual (staminate and pistillate on different plants); hypanthium shallowly cupulate, 0.3–0.5 mm, from constriction at apex of ovary, pubescent abaxially, often densely so; sepals 5, green to pale green, sometimes red-tinged, triangular, glabrate to pubescent abaxially; petals 0; stamens 5–10, long-exserted, with well-developed staminodia; nectary disc atop ovary, pubescent; ovary clearly flattened; style straight to slightly curved, free from hypanthium, with well-developed pistillode; ovules 2. Drupes somewhat flattened, ellipsoid to shortly obovoid, ridged or winged; ridges 2, forming shortly developed wings, slightly convex abaxially, concave adaxially; hypanthium and calyx persistent; fruits densely clustered in conelike heads, fragmenting in age.
