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.
