Leaf: generally basal and cauline, alternate or opposite, simple or compound; petioles at base generally flat, occasionally sheathing or stipule-like. Inflorescence: cyme, raceme, panicle, or flowers 1. Flower: generally bisexual, generally radial; sepals 3–6(20), free, early-deciduous or withering in fruit, generally green; petals 0–many, generally free; stamens generally 5–many, staminodes generally 0; pistils 1–many, ovary superior, chamber 1, style 0–1, generally ± persistent as beak, ovules 1–many.
