Annual to small tree; sap colorless, yellow, orange, red, or white.
Leaf: basal, cauline, or both, simple and entire, toothed, or lobed, or 1–3-pinnate- dissected or compound; cauline generally alternate; stipules 0.
Inflorescence: terminal, 1-flowered or cyme, raceme, or panicle; bracts generally present.
Flower: bisexual, radial, bilateral, or biradial; sepals 2–3, shed after flower; petals generally 2 × sepals in number; stamens generally many; ovary 1, superior, chamber 1, style 0 or 1, stigmas or lobes 2–many, ovules few to many.
Fruit: capsule, dehiscent by valves or pores, ± nut, or breaking transversely into 1-seeded, indehiscent units.
Seed: fleshy appendage generally 0.
25–30 genera, 200 species: n temperate, n tropics; some cultivated (Papaver, Eschscholzia, Hunnemannia), source of opiates. Stylomecon moved to Papaver. Corydalis, Dicentra, Fumaria in Fumariaceae in FNANM, elsewhere. Glaucium flavum Crantz is a waif. According to FNANM (3:300–301), Hunnemannia fumariifolia Sweet (± like Eschscholzia except sepals free) an occasional waif in CA, but documentation evidently lacking. Fleshy appendage of seed sometimes for dispersal by ants. —Scientific Editor: Thomas J. Rosatti.
