Genera In Family: 25--30 genera, 200 species: northern temperate, northern tropics; some cultivated (Papaver, Eschscholzia, Hunnemannia), source of opiates. Note: 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 California, but documentation evidently lacking.
