Aromatic trees or shrubs; leaves simple, margins entire and lobed in one genus. Leaves alternate, with prominent stipular scars that encircle the twig; the stipules themselves are caducus (quickly deciduous). Flowers large, showy, with characteristics generally considered primitive: actinomorphic, perfect, with multiple whorls of 3 tepals; many laminar stamens; many free carpels; and the stamens and carpels spirally arranged on an elongate receptacle. Fruits are an aggregate of follicles or achenes and appear cone-like.
