Papaver hybridum
ROUGH 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: PapaverView DescriptionDichotomous Key


Habit: Annual [perennial herb]; sap white, orange, or red. Leaf: basal and cauline [or basal], deeply pinnate-lobed, glabrous or hairy, glaucous or not. Inflorescence: axillary or terminal, 1-flowered. Flower: bud nodding; sepals 2, shed at flower; petals generally 4, free, obovate to wedge-shaped, white to red or purple; stamens many, free; placentas 4--20, style 0(1), stigma disk- or head-like, lobes 4--20. Fruit: dehiscent by pores below stigma. Seed: many, < 0.7 mm, reniform, net-ridged, brown or black.
Etymology: (Latin: poppy) Note: Papaver dubium L. (fruit +- oblong, glabrous; peduncle hairs near flower appressed, stiff), perhaps in California as waif.

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.
