Annual, perennial herb; hairs often hard from calcium deposits; generally monoecious. Stem: trailing or climbing, 1–many; tendril generally 1 per node, often branched. Leaf: generally simple, alternate, generally palmate-lobed and -veined, petioled; stipules 0. Inflorescence: at nodes; staminate flowers in racemes, panicles, small clusters, (or 1); pistillate flowers generally 1. Flower: unisexual [bisexual], radial; hypanthium > ovary; calyx generally 5-lobed (or ± 0); corolla rotate to cup- or bell-shaped, generally 5-lobed; stamens 3–5 (or ± 1–3 from fusion), anthers twisted together, often > filaments; ovary ± inferior, chambers 3–5, placentas parietal, styles 1–3, stigmas generally lobed, large. Fruit: berry, drying or not, or capsule, irregularly dehiscent, often gourd- or melon-like. Seed: 1–many.
100 genera, 700 species: especially tropics; some cultivated (Citrullus, watermelon; Cucumis, cucumber; Cucurbita, gourd, pumpkin, squash; Luffa, loofah; Sechium, chayote). [Schaefer et al. 2009 Proc Roy Soc London Ser B, Biol Sci 276:843–851] Several cultivated species included Bryonia dioica reported as waifs in California (Howell 1958 Wasmann J Biol 16:1–157), but none recently. —Scientific Editors: Douglas H.

Key to Cucurbitaceae
Perennial herb; tuber large; occasionally temporarily dioecious. Stem: ± scabrous or hairy, glabrous in age; tendril branched. Leaf: ± round, ± cordate, ± 5–7-lobed. Inflorescence: staminate flowers in racemes or panicles (or 1 flower per node early); pistillate flower 1 per node, generally at same nodes as staminate. Flower: sepals 0; staminate flower 3–15 mm wide, rotate to cup-shaped, white to cream or yellow-green; stamens fused, anthers twisted together; stigma (pistillate flowers) 1, ± hemispheric. Fruit: capsule, irregular-dehiscent from tip, ± symmetric, 3–20 cm, spheric to ovate or oblong, ± prickly, beak << body or 0. Seed: 1–many, generally > 1 cm, ± ovate, ± flat.Key to Marah
