Leaves alternate, simple or pinnatifid; stipules absent or present; petiole present. Leaf blade commonly with peltate, multicellular, glandular trichomes. Inflorescences axillary catkins; bracts present. Flowers usually unisexual, occasionally bisexual, staminate and pistillate flowers usually on different plants, occasionally on same plants; perianth absent. Staminate flowers subtended by solitary bract; stamens 2-14(-22), hypogynous or ± epigynous; filaments filiform, distinct or basally connate; anthers dorsifixed, 2-locular, extrorsely dehiscent by longitudinal slits. Pistillate flowers subtended by solitary bract, bracteoles present or absent, usually 2-4(-8); pistils 1, 2-carpellate, 1-locular; ovules 1, basal, erect; styles, if present, short; stigmas 2. Fruits drupaceous or nutlike, smooth or often covered with warty protuberances, these commonly with waxy coating; fruits sometimes enclosed by persistent, accrescent bracts and bracteoles.
