Papaveraceae papavə'rese, informally kent as the puppie faimily, is an economically important faimily o 30 genera an aboot 600 species o flouerin plants in the order Ranunculales. The faimily is cosmopolitan, occurrin in temperate an subtropical climates, but almaist unkent in the tropics. Maist are yerbaceous plants, but a few are shrubs an smaa trees.

Description[eedit | eedit soorce]

Mexican prickly puppie - flouer

The plants mey be annual, biennial, or perennial. Uisually yerbaceous, a few species fairm scrogs or evergreen trees. Thay are lactiferous, producin latex, whilk mey be milky or wattery, coloured or plain. Aw pairts contain a weel-developed duct seestem (these ducts are cried "laticifers"), producin a milky latex, a wattery white, yellae or reid juice.

The simple leaves are alternate or whiles whorled. Thay hae petioles an are nae enclosed bi a sheath. The leaves are usually lobed or pinnatifid (i.e. consisting o several nae entirely separate leaflets), or much-divided. There are no stipules.

The plants are hermaphroditic an are pollinatit maistly bi insects (even as flouer nectaries are lackin; entomophilous), a few bi the wind (anemophilous). There is a distinct calyx an corolla, except in Macleaya whaur the corolla is lackin. The flouers is medium-sized or lairge an thay leuk spectacular. The terminal flouers solitar in maist species. In ithers the terminal inflorescence is cymose or racemose. The flouers is odourless an regular.

Thare mony stamens, maistly 16 tae 60, arranged in twa separate whorls, the ooter ane wi stamens alternate wi the petals, the inner ane opposite. The gynoecium consists o a compound pistil wi 2 tae 100 carpels. The ovary is superior an 1-locular. The ovary is athoot a footstalk (sessile) or on a short stem (stipitate).

The non-fleshy fruit is uisually a capsule, breakin open at maturity tae release the seeds through pores (poricidal), or through the partitions atween the cells (septicidal), or bi means o valves (valvular). The numerous seeds is smaa. Their nutritive tissue (endosperm) is oily an farinose. The fruit o Platystemon is a schizocarp. Naur aw o these plants contain alkaloids. Mony are pushionous. The Mexican Prickly puppie is poisonous if taken internally an mey cause edema an glaucoma. Even gif an animal, like a gait, shoud persist in grazin on this plant, nae anly will the animal suffer but the like will be for thaim that drink its milk, acause the pushions is passed alang in the milk.

Taxonomy[eedit | eedit soorce]

The APG II seestem (2003; unchynged frae the APG seestem o 1998) places the faimily in the order Ranunculales, in the clade eudicots. Housomever, APG daes provide for the option tae segregate twa faimilies, as optional segregate. Thus, there twa possible circumscriptions:

  • Papaveraceae sensu lato, includin the plants that woud itherwise fairm the faimilies Fumariaceae an Pteridophyllaceae. (see subfaimilies)
  • Papaveraceae sensu stricto, excludin thir plants.

The faimily sensu stricto confairms tae the faimily as recognised bi the Cronquist seestem, o 1981 (Cronquist recognised Fumariaceae as separate). This comprises aboot 26 genera an aboot 250 species. The description gien abuin applies tae the faimily in this narra sense.

Subfaimilies[eedit | eedit soorce]

For discussions o subfaimilies, see Carolan et al. (2006) an Blattner an Kadereit (1999): Eschscholzioideae, Papaveroideae (includin Platystemonoideae), an Chelidonioideae.

The twa taxa considered subfaimilies that hae been considered as separate faimilies is the Fumariaceae (Bercht. & J. Presl, 1820) an the Pteridophyllaceae (Murb., 1912) Nakai ex Reveal & Hoogland, 1991.

Cultivation[eedit | eedit soorce]

The faimily is weel luved for the strikin flouers, wi mony species grawn as ornamental plants, includin Californie puppie (Eschscholtzia californica, the Californie state flouer), the stunnin blue Himalayan poppies (Meconopsis), several species o Papaver, an the wildflouer bloodruit. The faimily conteens the opium puppie (Papaver somniferum) an aw, whilk is the soorce of opium an opiates, as weel as puppie seeds uised in cuikin an bakin, an puppieseed ile.

Seembolism[eedit | eedit soorce]

Main article: puppie

The opium puppie an corn puppie is seembols, respectively, o sleep an daith. In Great Breetain, Canadae, the Unitit States, an Australie the corn puppie is worn in remembrance o Warld War I.
