Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', ''Ismene (plant), Ismene'' and ''Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, ''N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped Corona (plant structure), corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Carl Linnaeus, Linnaeus in his ''Species Plantarum'' (1753). The genus ...

Narcissus Pseudonarcissus
''Narcissus pseudonarcissus'' (commonly known as wild daffodil or Lent lily) (Welsh: Cennin Pedr) is a perennial flowering plant. This species has pale yellow tepals, 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 seed 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, Newf ...

Electron Micrograph
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gomphrena Globosa
''Gomphrena globosa'', commonly known as globe amaranth, is an edible plant from the family Amaranthaceae. The round-shaped flower inflorescences are a visually dominant feature and cultivars have been propagated to exhibit shades of magenta, purple, red, orange, white, pink, and lilac. Within the flowerheads, the true flowers are small and inconspicuous. ''Gomphrena globosa'' is native to Central America including regions Panama, and Guatemala, but is now grown globally. As a tropical annual plant, ''G. globosa'' blooms continuously throughout summer and early fall. It is very heat tolerant and fairly drought resistant, but grows best in full sun and regular moisture. The plant fixes carbon through the C4 carbon fixation, C4 pathway. At maturity, the flowerheads are approximately 4cm long and the plant grows up to 24 inches in height. ''Gomphrena globosa'' is an outcrossing species that is pollinated by butterflies, bees, and other insects. Floral volatiles likely play a signifi ...
