Poppy

罂粟是产于温带和亚热带的植物。它具有麻醉作用的白色乳液,结有深红色等鲜艳的花,圆形的蒴果中含有无数种子。
POPPY (罂粟) is a flowering plant occurring principally in the North Temperate Zone.
It has lobed (裂片) or dissected leaves, milky sap (液汁), nodding buds (下垂的花蕾) on solitary (单个的) stalks (叶柄), and four- to six-petaled flowers with numerous (许多的) stamens (雄蕊) surrounding the ovary (子房).
The ovary develops into a short, many-seeded capsule (蒴果) that opens in dry weather, permitting the small seed to escape when it is shaken by the wind.
The family contains about 210 species; many are important as ornamentals.
Opium, from which morphine (吗啡), heroin (海洛因), codeine (可待因) and papaverine (罂粟碱) are derived, comes from the milky fluid in the capsule of the opium poppy, native to Anatolia (安纳托利亚,小亚西亚的旧称).
An annual plant, it bears 12.7-centimetre-wild blue-purple or white flowers on plants one to five m tall. The opium poppy also is grown for its nonnarcotic (非麻醉性的) seeds, used for seasoning, oil, and birdseed.
The poppy family is well represented in western North America, especially in California, where about 20 native species are found. The best-known of these is the California poppy, an annual with brilliant orange-coloured flowers, extensively naturalized in California, Australia and India.
The Oriental poppy is widely cultivated as an ornamental, and many colour forms have been developed. (SD-Agencies)
