Eschscholzia minutiflora subsp. minutiflora

PYGMY POPPY


Higher Taxonomy
Family: PapaveraceaeView DescriptionDichotomous Key
Common Name: POPPY FAMILY
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-ternate-dissected, segments narrow to wide. 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 8--many, free; carpels 2, style 0, stigma lobes 4, 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.
Etymology: (J.F.G. von Eschscholtz, Russian surgeon, botanist, 1793--1831)

Species: Eschscholzia minutifloraView Description 


Habit: Annual, erect or spreading, 5--35 cm, glabrous, gray- or blue-glaucous. Leaf: segments short, generally obtuse, entire to shallowly notched; distalmost cauline leaves with > 8 segments. Inflorescence: 1--many-flowered, each pedicel subtended by a leaf. Flower: bud nodding, short-pointed with tip generally < 1/4 bud, glabrous, occasionally glaucous; receptacle obconic; petals 3--26 mm, yellow, base occasionally orange-spotted. Fruit: 2.4--8 cm. Seed: 1--1.4 mm wide, generally oblong to elliptic, net-ridged, brown to black. Chromosomes: 2n=12,24,36.
Note: The three subspecies recognized here co-occur and warrant elevation to species rank.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
