ABSTRACT
Trees or shrubs, rarely subscandent, usually secreting resin or oil but without pellucid gland-dots in the leaves; the outer bark often peeling off in flakes, scrolls, strips or sheets, usually translucent, transmitting light to the green or bluish green under-bark. Leaves spirally arranged, usually without stipules, imparipinnate, 1–3-foliolate or occasionally simple, rarely bipinnate in America. Flowers rather small, regular, bisexual or imperfectly unisexual and dioecious, in panicles, corymbs, racemes, cymes or fascicles, or solitary. Receptacle saucer-shaped or cupular; calyx, ± divided into 3–5(–6) usually valvate lobes. Petals (0–)3–5(–6), valvate or imbricate, almost always free. Stamens placed outside or on the margin of a disc, (3–5)–6, 8 or 10(–12), usually twice as many as the petals and in 2 whorls. Ovary superior, 2–5(6–8)-locular, with 2 ovules pendent from the apex of each locule1*. Fruit a 1–5-seeded drupe or pseudocapsule**.
