Higher Taxonomy
Family: PapaveraceaeView DescriptionDichotomous Key

Habit: 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.
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. Fleshy appendage of seed sometimes for dispersal by ants.

Genus: EschscholziaView DescriptionDichotomous Key

Habit: 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.
Species In Genus: 12 species: western North America. Etymology: (J.F.G. von Eschscholtz, Russian surgeon, botanist, 1793--1831)

Eschscholzia minutiflora S. Watson
Habit: 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. Chromosomes: 2n=12,24,36.
Ecology: Desert washes, flats, slopes; Elevation: < 2600 m. Bioregional Distribution: se SCoRO, SNE, D; Distribution Outside California: to southern Nevada, southwestern Utah, western Arizona, northwestern Mexico. Flowering Time: Mar--May Note: Variable; further study needed to determine if Eschscholzia minutiflora subsp. covillei (Greene) C. Clark (petals 6--18 mm; 2n=24; northern and central DMoj), Eschscholzia minutiflora subsp. twisselmannii C. Clark & M. Faull (petals 10--26 mm; 2n=12; western DMoj) deserve taxonomic recognition.
