Galanthus Peshmenii
''Galanthus'' (from Ancient Greek , (, "milk") + (, "flower")), or snowdrop, is a small genus of approximately 20 species of bulbous perennial herbaceous plants in the family Amaryllidaceae. The plants have two linear leaves and a single small white drooping bell-shaped flower with six petal-like ( petaloid) tepals in two circles (whorls). The smaller inner petals have green markings. Snowdrops have been known since the earliest times under various names, but were named ''Galanthus'' in 1753. As the number of recognised species increased, various attempts were made to divide the species into subgroups, usually on the basis of the pattern of the emerging leaves ( vernation). In the era of molecular phylogenetics this characteristic has been shown to be unreliable and now seven molecularly defined clades are recognised that correspond to the biogeographical distribution of species. New species continue to be discovered. Most species flower in winter, before the vernal equinox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galanthus Nivalis
''Galanthus nivalis'', the snowdrop or common snowdrop, is the best-known and most widespread of the 20 species in its genus, ''Galanthus''. Snowdrops are among the first bulbs to bloom in spring and can form impressive carpets of white in areas where they are native or have been naturalised. They should not be confused with the snowflakes, in the genera ''Leucojum'' and '' Acis''. Naming The generic name ''Galanthus'', from the Greek ''gala'' (milk) and ''anthos'' (flower), was given to the genus by Carl Linnaeus in 1735. He described ''Galanthus nivalis'' in his ' published in 1753. The epithet means "of the snow", referring either to the snow-like flower or the plant's early flowering. The common name snowdrop first appeared in the 1633 edition of John Gerard's ''Great Herbal'' (in the first edition (1597) he described it as the "Timely flowring Bulbus violet"). The derivation of the name is uncertain, although it may have come from the German word ''Schneetropfen'', which wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vernation
Vernation (from ''vernal'' meaning ''spring'', since that is when leaves spring forth in temperate regions) is the formation of new leaves or fronds. In plant anatomy, it is the arrangement of leaves in a bud. In pine species, new leaves are short and encased in sheaths. Each leaf bundle consists of 2 to 5 needles. All the leaves on one section of branch grow in length together. In cabbage species, new leaves are folded over, each covered by the previous leaf. Circinate vernation Circinate vernation is the manner in which most fern fronds emerge. As the fern frond is formed, it is tightly curled so that the tender growing tip of the frond (and each subdivision of the frond) is protected within a coil. At this stage it is called a '' crozier'' (after the shepherd's crook) or ''fiddlehead'' (after the scrollwork at the top of a violin). As the lower parts of the frond expand and toughen up, they begin to photosynthesize, supporting the further growth and expansion of the frond. ...
