Leaf: simple to ternate- or odd-pinnate-compound, alternate, deciduous or evergreen; stipules 0. Inflorescence: raceme or panicle; flowers generally many. Flower: generally unisexual, radial; sepals generally 5, base generally ± fused; petals 5, generally > sepals, free; (perianth parts 1–7 in Pistacia); stamens 4–7 or 10, vestigial in pistillate flowers; ovary superior, vestigial or 0 in staminate flowers, subtended by ± lobed, disk-like nectary, chamber generally 1, ovule generally 1, styles 1–3.
