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.

Key to Vitaceae
Stem: bark peeling; stem center brown, partitioned at nodes; tendril tips without adhering disks. Leaf: simple, crenate to serrate. Inflorescence: panicle of often head- or umbel-like clusters. Flower: unisexual or bisexual; calyx ± green, lobes 0 or short; petals adherent at tips, ± yellow; stamens 3–9 mm, generally erect, in pistillate flowers reflexed and sterile or 0; nectaries ± free glands. Fruit: 4–20 mm wide, spheric to ovoid, glaucous or not. Seed: 1–4, obovoid.Key to Vitis
65 species: temperate, subtropics. (Latin: vine) Vitis californica, Vitis girdiana differ in nuclear rDNA sequences.

Stem: hairy, generally glabrous in age; nodal partitions generally 3–5 mm thick. Leaf: cordate to reniform, generally serrate, glabrous or hairy, lobes 0 or 3–5, deep; stipules generally < 3.5 mm. Flower: bisexual. Fruit: generally > 8 mm wide, spheric to ovoid, purple to blue-black, densely to not glaucous; skin adherent to pulp. Seed: round structure opposite attachment scar sunken or raised.
