Nasturtium (genus)
''Nasturtium'' () is a genus of a small number of plant species in the family Brassicaceae (cabbage family) commonly known as watercress or yellowcress. The best known species are the edible ''Nasturtium officinale'' and ''Nasturtium microphyllum''. ''Nasturtium'' was previously synonymised with ''Rorippa'', but molecular evidence supports its maintenance as a distinct genus more closely related to ''Cardamine'' than to ''Rorippa'' ''sensu stricto''. These plants are related to garden cress and mustard, noteworthy for a peppery, tangy (pungent) flavor. The name ''Nasturtium'' comes from the Latin ''nasus tortus'', meaning "twisted nose", in reference to the effect on the nasal passages of eating the plants. ''Nasturtium'' foliage is used as food by the caterpillars of certain Lepidoptera, including ''Orthonama obstipata'' (The Gem). One species, '' Nasturtium gambellii'', is federally listed in California as an endangered species. Nomenclature The genus ''Nasturtium'' should ...

Watercress
Watercress or yellowcress (''Nasturtium officinale'') is a species of aquatic flowering plant in the cabbage family, Brassicaceae. Watercress is a rapidly growing perennial plant native to Eurasia. It is one of the oldest known leaf vegetables consumed by humans. Watercress and many of its relatives, such as garden cress, mustard, radish, and wasabi, are noteworthy for their piquant flavors. Description Watercress can grow up to in length. The stems are hollow and float in water. The leaf structure is pinnately compound. Small, white, and green inflorescences are produced in clusters and are frequently visited by insects, especially hoverflies, such as '' Eristalis'' flies. Taxonomy Watercress is listed in some sources as belonging to the genus ''Rorippa'', although molecular evidence shows those aquatic species with hollow stems are more closely related to ''Cardamine'' than ''Rorippa''. Despite the Latin name, watercress is not particularly closely related to the fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthonama Obstipata
''Orthonama obstipata'', the gem, is a moth of the family Geometridae. The species was Species description, first described by Johan Christian Fabricius in 1794. It is a cosmopolitan species. In continental Europe though in the northeast, its range does not significantly extend beyond the Baltic region and it is absent from northern Russia. This well-flying species is prone to vagrancy and able to cross considerable distances of the open sea; it can thus be regularly found on the British Isles (though mainly in the south) and even on Iceland. Under its junior synonyms ''Nycterosea brunneipennis'' and ''Geometra fluviata'', the gem is the type species of genera ''Nycterosea'' and ''Percnoptilota'', respectively. The latter is treated as a junior synonym of the former, but ''Nycterosea'', though usually included in ''Orthonama'' these days, may warrant recognition as an independent genus after all. Description and ecology The adult's wingspan is ; in their core range (e.g. Belgium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rorippa Africana
''Rorippa'' is a globally distributed genus in the family Brassicaceae, with species occurring on all continents except for Antarctica. ''Rorippa'' species are natively distributed in the Northern Hemisphere through Eurasia and North America, and dispersed into the Southern Hemisphere through long-distance dispersal. ''Rorippa'' species are annual to perennial herbs, usually with yellow flowers and a peppery flavour. They are known commonly as yellowcresses. Description As a close relative of ''Arabidopsis'', ''Rorippa'' has emerged as a group of valuable model organisms for investigating various biological processes. Researchers have utilized ''Rorippa'' to study developmental phenomena such as heterophylly, weediness, and vegetative regeneration. For example, heterophylly is the ability of plants to produce different leaf forms in response to contrasting environments, such as aerial or submerged conditions. This may incur anatomical or physiological changes and facilitate adap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orthographical Variant
In biology, within the science of Nomenclature, scientific nomenclature, i.e. the naming of organisms, an orthographical variant (abbreviated orth. var.) in botany or an orthographic error in zoology, is a spelling mistake, typing mistake or writing mistake within a scientific publication that resulted in a somewhat different name being accidentally used for an already-named organism. The rules that govern what to do when this happens are laid out in the relevant codes of nomenclature. In botanical names In botanical nomenclature, an orthographical variant (abbreviated orth. var.) is a variant spelling of the same name. For example, ''Hieronima'' and ''Hyeronima'' are orthographical variants of ''Hieronyma''. One of the spellings must be treated as the Correct name (botany), correct one.ICBNVienna Code(2006), Article 61 In this case, the spelling ''Hieronyma'' has been conserved name, conserved and is to be used as the correct spelling.

Tropaeolum Majus
''Tropaeolum majus'', the garden nasturtium, nasturtium, Indian cress or monk's cress, is a species of flowering plant in the family Tropaeolaceae, originating in the Andes from Bolivia north to Colombia. An easily-grown annual or short-lived perennial with disc-shaped leaves and brilliant yellow, orange or red flowers, it is of cultivated, probably hybrid origin.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . It is not closely related to the genus '' Nasturtium'' (which includes watercress). Description It is a fast-growing plant, with trailing stems growing to . The leaves are large, nearly circular, in diameter, green to glaucous green above, paler below; they are peltate, with the 5–30-cm-long petiole near the middle of the leaf, with several veins radiating to the smoothly rounded or slightly lobed margin. The flowers are 2.5–6 cm in diameter, mildly scented, with five petals, eight stamens, and a 2.5–3 cm long nectar spur at the ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. Globally, 6% of all plant species and 15% of herbaceous plants (excluding trees and shrubs) are annuals. The annual life cycle has independently emerged in over 120 different plant families throughout the entire angiosperm phylogeny. The evolutionary and ecological drivers of the annual life cycle Traditionally, there has been a prevailing assumption that annuals have evolved from perennial ancestors. However, recent research challenges this notion, revealing instances where perennials have evolved from annual ancestors. Intriguingly, models propose that transition rates from an annual to a perennial life cycle are twice as fast as the reverse transition. The life-history theory posits that annual plants are favored when adult mortality is higher than seedling (or seed) mortality, i.e., annuals will dominate environments with dis ...

Ornamental Plant
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
