''Narcissus pseudonarcissus'' (commonly known as wild daffodil or Lent lily) is a perennial flowering plant.〔(Linnaeus, Carl. 1753. Species Plantarum 1: 289, ''Narcissus pseudonarcissus'' )〕〔Gray, Samuel Frederick. 1821. Natural Arrangement of British Plants, According to Their Relation to Each Other 2:191, as ''Ajax fenestralis''〕〔Jordan, Claude Thomas Alexis. 1903. Jord. & Fourr. Icon. Fl. Eur. iii. 2. as ''Ajax festinus''〕〔Pugsley, Herbert William. 1933. Journal of the Royal Horticultural Society 1933, 58:72, as ''Narcissus gayi''〕〔Sell, Peter Derek. 1996. Flora of Great Britain and Ireland 5: 364, as ''Narcissus pseudonarcissus'' forma ''pleniflorus''〕〔Haworth, Adrian Hardy. 1831. Monog. Narciss. 4, as ''Oileus hexangularis''〕 This species has pale yellow flowers, with a darker central trumpet. The long, narrow leaves are slightly greyish green in colour and rise from the base of the stem. The plant grows from a bulb. The flowers produce seeds, which when germinated, take five to seven years to produce a flowering plant. (Sexual () reproduction mixes the traits of both parent flowers, so if garden hybrid cultivars are planted close to wild populations of ''Narcissus pseudonarcissus'', there is a danger that the new seedlings, having hybrid vigour, could out-compete the wild plants.) ==Distribution== The species is native to Western Europe from Spain and Portugal east to Germany and north to England and Wales. It is commonly grown in gardens and populations have become established in the Balkans, Australia, New Zealand, the Caucasus, Madeira, British Columbia, Ontario, Newfoundland, Oregon, Washington State, much of eastern United States, and the Falkland Islands. Wild plants grow in woods, grassland and on rocky ground. In Britain native populations have decreased substantially since the 19th century due to intensification of agriculture, clearance of woodland and uprooting of the bulbs for use in gardens. In Germany it was a subject of a national awareness campaign for the protection of wildflowers in 1981. In England, in the North York Moors National Park, the Farndale valley hosts a large population of the species, along the banks of the River Dove. In England, in Gloucestershire, there are several nature reserves supporting large populations of the species near Dymock Woods SSSI. There is a Daffodil Walk Trail around several reserves in the spring.〔2011, 'Nature Reserve Guide', Gloucestershire Wildlife Trust published for its 50th anniversary〕〔'The Daffodil Trails', (undated), Gloucestershire Wildlife Trust〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Narcissus pseudonarcissus」の詳細全文を読む スポンサード リンク
