Description

Family Papaveraceae

Herbs or subshrubs , shrubs , or small trees , annual , biennial, or perennial , scapose or caulescent , usually from taproots , sometimes from rhizomes; sap clear, white, or colored , often sticky. Stems leafy or naked, erect , spreading , or decumbent , simple or branching. Leaves basal and/or cauline, alternate to opposite or whorled , simple, without stipules, petiolate or sessile; blade unlobed or with 1-3 odd-pinnate, subpalmate, or palmate orders of lobes . Inflorescences axillary or terminal , unifloral or else multifloral and cymiform, racemose, umbelliform, corybiform, or paniculate , pedunculate or subsessile ; bracts usually present. Flowers radially symmetric , pedicellate or sessile; receptacle sometimes expanded and forming cup or ring beneath calyx (only in Eschscholzia, Meconella, and Platystemon ) ; perianth and androecium sometimes perigynous; sepals caducous , 2 or 3, distinct or connate , usually obovate ; petals distinct, usually obovate, mostly 2 times number of sepals, sometimes more or absent; stamens many or 4-15 (only in Meconella and Canbya ) ; anthers 2-locular; pistil 1, 2-18[-22]-carpellate; ovary 1-2-locular or incompletely to completely multilocular by placental intrusion; placentas 2 or more, parietal ; style 1 or absent; stigmas or stigma lobes 2-many. Fruits capsular , dehiscence valvate , poricidal , or transverse , or carpels dissociating and breaking transversely into 1-seeded segments (only in Platystemon ) . Seeds usually many, small, sometimes arillate or carunculate.

Genera 25-30 (17 genera, 63 species in the flora ) : worldwide, mainly Northern Hemisphere.

According to W. R. Ernst (1962b), Papaveraceae "may be divided conveniently into four subfamilies." His scheme is followed here, but with the subfamilies taken up in alphabetic order; they seem to be natural groups, but their phylogenetic interrelationships are not yet clear. Similarly, the evolutionary relationships within the subfamilies remain ambiguous, and the genera in each are listed alphabetically. Subfamily Chelidonioideae Ernst includes genera 1-5; subf. Eschscholzioideae Ernst, genera 6-7; subf. Papavaroideae Ernst, genera 8-14; and subf. Platostamenoideae Ernst, genera 15-17.Robert W. Kiger "Papaveraceae". in Flora of North America Vol. 3.

Genus Papaver

Herbs, annual , biennial, or perennial , scapose or caulescent , from taproots ; sap white, orange, or red. Stems when present leafy. Leaves: basal rosulate, petiolate ; cauline alternate, proximal leaves petiolate, distal subsessile or sessile, sometimes clasping (in P . somniferum ) ; blade unlobed or 1-3× pinnately lobed or parted ; margins entire or toothed , scalloped, or incised. Inflorescences cymiform, with flowers disposed in 1s, 2s or 3s on long scapes or peduncles ; bracts present; buds nodding [erect ]. Flowers: sepals 2(-3), distinct ; petals 4(-6) ; stamens many; pistil 3-18[-22]-carpellate; ovary 1-locular, sometimes incompletely multilocular by placental intrusion; style absent; stigmas 3-18[-22], radiating on sessile, ± lobed disc, velvety . Capsules erect, 3-18[-22]-pored or short-valved immediately beneath persistent or sometimes deciduous (in P . hybridum ) stigmatic disc. Seeds many, minutely pitted , aril absent. x = 7.

Species 70-100: temperate and arctic North America, Eurasia , n, s Africa, Australia.

Papaver is rich in alkaloids, notably opiates. The genus is quite complex cytologically; in addition to diploids, there are numerous polyploid species and some that apparently are aneuploid . Most commonly, n = 7 or a multiple , and 2 n ranges from 14 to over 100. There are published chromosome counts for almost every taxon in the flora , but for the introduced species none has been made from wild-collected North American material .

The scapose poppies in the flora are native ; the caulescent ones, except Papaver californicum, are introduced Eurasian ornamentals , crop weeds , and ballast waifs . All the scapose species are confined to arctic and alpine habitats . Plants of the introduced caulescent species, especially P . rhoeas, P . dubium, and P . somniferum, vary greatly in size, and surprisingly diminutive mature individuals are sometimes found, especially northward.Robert W.
