Inflorescence: cyme, panicle, generally opposite leaf, peduncled. Flower: generally bisexual, radial; sepals generally reduced, generally fused, lobes 0 or 5; petals generally 5, free, reflexed, falling individually, or adherent at tips, ± erect, falling as unit, ± red or ± yellow; stamens generally 5, opposite petals; nectaries 0 or between stamens as ± free glands; ovary 1, superior, chambers generally 2(4), style 1 or 0, stigma inconspicuous or head-like. Fruit: berry. Seed: 1–6.
15 genera, ± 800 species: especially warm regions; some cultivated (Cissus, grape ivy; Parthenocissus, Virginia creeper; Vitis, grape). [Chen & Manchester 2007 Amer J Bot 94:1534–1553] —Scientific Editor: Thomas J. Rosatti.
