Empetrum
''Empetrum'' is a genus of three species of dwarf evergreen shrubs in the heath family Ericaceae. They are commonly known as crowberries and bear edible fruit. They are commonly found in the northern hemisphere, from temperate to subarctic climates, and also in the Southern Andes of South America and on the South Atlantic islands of South Georgia, the Falklands and Tristan da Cunha. The typical habitat is on moorlands, tundra, muskeg and spruce forests. They are also often found in areas of coastal exposure on the sand dunes and dune slacks. Species of ''Empetrum'' include: '' E. nigrum'' (crowberry or black crowberry) and its tetraploid subspecies ''E. nigrum'' ssp. ''hermaphroditum'', '' E. eamesii'' (rockberry or purple crowberry) and '' E. rubrum'' (red crowberry). All are evergreen mat forming shrubs, with small, light green needle-like leaves 3–10 mm long. The flowers are small and either bisexual or dioecious. The fruit is a fairly dry berry. The plant has slender, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empetrum Nigrum
''Empetrum nigrum'', crowberry, black crowberry, or, in western Alaska, blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the Northern Hemisphere. It is usually dioecious, but there is a bisexual tetraploid subspecies, ''Empetrum nigrum'' subsp. ''hermaphroditum'', which occurs in more northerly locations and at higher altitude. Description ''Empetrum nigrum'' is a low growing, evergreen shrub with a creeping habit. The leaves are long, arranged alternately along the stem. The stems are red when young and then fade to brown. It blooms between May and June. The flowers are small and not very noticeable, with greenish-pink sepals that turn reddish purple. The round fruits are drupes, wide, usually black or purplish-black but occasionally red. The metabolism and photosynthetic parameters of ''Empetrum'' can be altered in winter-warming experiments.

Empetrum Eamesii
''Empetrum eamesii'', common name purple crowberry, is a plant native to eastern Canada and the northeastern United States. It has been reported from sand dunes, rocky outcrops, and alpine heath in Québec, Nova Scotia, Prince Edward Island, Maine, New Hampshire, Vermont, New York State, the Upper Peninsula of Michigan, Minnesota (Cook County), Newfoundland & Labrador and St. Pierre & Miquelon. All the US and some of the Canadian material belongs to ''Empetrum eamesii'' subsp. ''atropurpureum'' (Fernald & Wiegand) D.Löve which has been regarded as a separate species by some authorities but not others.

Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Tristan Da Cunha
Tristan da Cunha (), colloquially Tristan, is a remote group of volcanic islands in the South Atlantic Ocean. It is the most remote inhabited archipelago in the world, lying approximately from Cape Town in South Africa, from Saint Helena and from the Falkland Islands. The territory consists of the inhabited island, Tristan da Cunha, which has a diameter of roughly and an area of ; the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. , the main island has 250 permanent inhabitants, who all carry British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel of a weather station on Gough Island. Tristan da Cunha is a British Overseas Territory with its own constitution. There is no airstrip on the main island; the only way of travelling in and out of Tristan is by boat, a six-day trip from South Africa. History Discovery The uninhabited islands were f ...

Ceratiola
''Ceratiola'' is a genus of flowering plants with a single species, ''Ceratiola ericoides'', the sand heath, sandhill-rosemary or Florida-rosemary, is a species of shrub usually included in the plant family Ericaceae, though treated by some botanists in the Empetraceae. It is the sole species in the genus ''Ceratiola''. It is native to subtropical scrub and dry sandy habitats in the coastal southeastern United States, in Alabama, Florida, Georgia, Mississippi and South Carolina. It commonly occurs together with sand pine and species of oak. Like sand pine, it is adapted to the harsh coastal environment where hot sun and fast draining white sandy soils are common. Cetatiola regenerate by seed after periodic forest fires. Its habitat is important for the endangered Florida sand skink (''Neoseps reynoldsi'') in central Florida. The name derives from the species' superficial similarity to the unrelated European shrub rosemary, familiar for its leaves used as a herb. Florida-rosem ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
