CUCURBITACEAE

GOURD FAMILY

Robert L. Schlising

Annual, perennial herb, generally monoecious; hairs often hardened by calcium deposits
Stems trailing or climbing, 1–many; tendril generally 1 per node, often branched
Leaves generally simple, alternate, generally palmately lobed, veined, petioled; stipule 0
Inflorescences at nodes; staminate flowers in racemes, panicles, small clusters, rarely solitary; pistillate flowers generally solitary
Flower unisexual in CA, radial; hypanthium > ovary; calyx (apparently 0 or) generally 5-lobed; corolla rotate or cup-shaped, generally 5-lobed; stamens 3–5 (or appearing 1–3 from fusion), anthers often > filaments, twisted together; ovary ± inferior, chambers generally 5, placentas parietal, ± growing into chambers, styles 1–3, stigmas generally lobed, large
