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: northern temperate, northern 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 California, but documentation evidently lacking. Fleshy appendage of seed sometimes for dispersal by ants. —Scientific Editor: Thomas J. Rosatti.
Key to Papaveraceae
Annual, perennial herb; sap colorless or orange. Leaf: basal or basal and cauline, 1–4-pinnate-dissected, segments narrow. Inflorescence: cyme, 1–many-flowered. Flower: receptacle funnel-shaped, tip cupped around ovary base, outer receptacle rim occasionally spreading; sepals 2, fused, shed as unit at flower; petals generally 4 (except doubled flowers), free, obovate or wedge-shaped, generally yellow to orange (white or pink), shed after flower leaving crown-like membrane (inner receptacle rim); stamens 12–many, free; carpels 2, style 0, stigma lobes 4–8, spreading, linear. Fruit: oblong, dehiscent from base. Seed: many, 1–2 mm, round to ovate, net-ridged, prominent-discontinuous-ridged, or minutely pitted, tan, brown, or black.Key to Eschscholzia
12 species: western North America. (J.F.G. von Eschscholtz, Russian surgeon, botanist, 1793–1831)
Annual, erect or spreading, 5–35 cm, glabrous, gray- or blue-glaucous. Leaf: segments short, generally obtuse, entire to shallowly notched. Flower: bud nodding, short-pointed, glabrous, occasionally glaucous; receptacle obconic; petals 3–6(26) mm, yellow, base occasionally orange-spotted. Fruit: 3–6 cm. Seed: 1–1.4 mm wide, generally oblong to elliptic, net-ridged, brown to black.
2n=12,24,36. Desert washes, flats, slopes; < 2600 m. se Outer South Coast Ranges, East of Sierra Nevada, Desert; to southern Nevada, southwestern Utah, western Arizona, northwestern Mexico. [Eschscholzia parishii, misappl.] Variable; further study needed to determine if Eschscholzia minutiflora subsp. covillei (Greene) C. Clark (petals 6–18 mm; 2n=24; northern and central Mojave Desert), Eschscholzia minutiflora subsp. twisselmannii C. Clark & M. Faull (petals 10–26 mm; 2n=12; western Mojave Desert) deserve taxonomic recognition. Mar–May [Online Interchange]
