Question: Which one of this from poppy family, Papaver or Corokia?
Context: Poppy straw (also mowed opium straw, crushed poppy capsule, poppy chaff, poppy husk) is derived from opium poppies ("Papaver somniferum") that are harvested when fully mature and dried by mechanical means, minus the ripe poppy seeds. Opium poppy straw today can be one of several different things.  It is what remains after the poppy seed harvest, that is, the dried stalks, stem and leaves of poppies grown for their seeds.  The dried leaves and stalk harvested after the seed pod have been used for traditional opium extraction.  The field dried leaves, stalk and seed pod are used in commercial manufacture of morphine or other poppy alkaloid derived drugs, by first processing the material to make poppy straw separating the seeds then making concentrate of poppy straw, where no extraction using traditional methods of latex extraction has been made.  The straw was originally considered an agricultural by-product of the mechanised poppy seed harvest, which was primarily grown for its edible and oil-producing seed.  This changed in 1927 when János Kabay developed a chemical process to extract morphine from the crushed capsule.  Concentrated poppy straw consisting mainly of the crushed capsule without the seeds soon became a valuable source of morphine.  Today, concentrate of poppy straw is a major source of many opiates and other alkaloids It is the source of 90% of the world supply of legal morphine (for medical and scientific use) and in some countries it also is a source of illegal morphine, which could be processed into illegal heroin. Papaver nudicaule (syn.  "Papaver croceum", "P. miyabeanum", "P. amurense", and "P. macounii"), the Iceland poppy, is a boreal flowering plant.  Native to subpolar regions of Europe, Asia and North America, and the mountains of Central Asia (but not in Iceland), Iceland poppies are hardy but short-lived perennials, often grown as biennials, that yield large, papery, bowl-shaped, lightly fragrant flowers supported by hairy, one foot, curved stems among feathery blue-green foliage 1-6 inches long.  They were first described by botanists in 1759.  The wild species blooms in white or yellow, and is hardy from USDA Zones 3a-10b.  All parts of this plant are likely to be poisonous, containing (like all poppies) toxic alkaloids.  In particular, "P. nudicaule" has been shown to contain the benzophenanthidine alkaloid, chelidonine.  It also contains (+)-amurine, (-)-amurensinine, (-)-O-methylthalisopavine, (-)-flavinantine and (-)-amurensine. Romneya trichocalyx, the bristly Matilija poppy or hairy Matilija poppy, is a species of flowering plant in the poppy family.  This poppy is native to San Diego, Ventura, and Santa Barbara counties in California, as well as Baja California, Mexico, where it grows in dry canyons in chaparral and coastal sage scrub plant communities.  Like its relative "Romneya coulteri", it is used as an ornamental plant, kept for its large, showy flowers. Papaver rupifragum is a species of flowering plant in the poppy family, Papaveraceae Meconic acid, also known as acidum meconicum and poppy acid, is a chemical substance found in certain plants of the Papaveraceae family (poppy) such as "Papaver somniferum" (opium poppy) and "Papaver bracteatum".  Meconic acid constitutes about 5% of opium and can be used as an analytical marker for the presence of opium.  Meconic acid has erroneously been described as a mild narcotic, but it has little or no physiological activity, and is not used medicinally.  Meconic acid forms salts with alkaloids and metals.  These salts as well as meconic acid esters are called meconates.  Meconic acid was first isolated by Friedrich Sertürner in 1805. A Good Thing Lost is a compilation album by The Poppy Family, released in 1996 in Canada and later on iTunes in America with a second cover.  The compilation was essentially The Poppy Family's greatest hits collection but also included a number of Susan Jacks' solo recordings.  The album featured an alternate mix of "There's No Blood In Bone" and previously unreleased track "Evil Overshadows Joe", along with the U.S. version of "That's Where I Went Wrong" with the lead guitar being recorded in Nashville, Tennessee. Corokia is a genus in the Argophyllaceae family comprising about ten species native to New Zealand and one native to Australia.  "Corokia" species are shrubs or small trees with zigzagging (divaricating) branches.  In fact, "Corokia cotoneaster" is commonly known as "wire-netting bush".  The stems of the shrubs are dark when mature, covered with downy or silky hairs (tomentum) when young.  In spring, they produce clusters of small, star shaped yellow blossoms.  Berries are red or yellow.  The shrubs prefer forests and rocky areas, sun or light shade, reasonably well drained soil, and moderate watering. Papaver rhoeas (common names include common poppy, corn poppy, corn rose, field poppy, Flanders poppy or red poppy) is an annual herbaceous species of flowering plant in the poppy family, Papaveraceae.  This poppy is notable as an agricultural weed (hence the common names including "corn" and "field") and after World War I as a symbol of dead soldiers. A poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae.  Poppies are herbaceous plants, often grown for their colorful flowers.  One species of poppy, "Papaver somniferum", is the source of the crude drug opium which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as an analgesic and narcotic medicinal and recreational drug.  It also produces edible seeds.  Following the trench warfare which took place in the poppy fields of Flanders during World War I, poppies have become a symbol of remembrance of soldiers who have died during wartime. Papaver is a genus of 70–100 species of frost-tolerant annuals, biennials, and perennials native to temperate and cold regions of Eurasia, Africa and North America.  It is the type genus of the poppy family, Papaveraceae.
