Jakob Friedrich Ehrhart
Jakob Friedrich Ehrhart (4 November 1742, Holderbank, Aargau – 26 June 1795) was a German botanist, a pupil of Carl Linnaeus at Uppsala University, and later director of the Botanical Garden of Hannover, where he produced several major botanical works between 1780 and 1793. Ehrhart was the first Author (botany), author to use the rank of subspecies in botanical literature, and he published many subspecific names between 1780 and 1789. Ehrhart issued several exsiccata, exsiccatae, the first one ''Phytophylacium Ehrhartianum, continens plantas, quas in locis earum natalibus collegit et exsiccavit Fridericus Ehrhart'' (1780-1785).Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – München, Germany. He was one of the first who prepared exsiccatae for selling them to colleagues, namely the series ''Arbores, frutices et suffrutices Linnaei quas in usum dendrophilorum collegit et exsic ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Tree
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, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Types of pasture Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with e ...

Nordic Countries
The Nordic countries (also known as the Nordics or ''Norden''; ) are a geographical and cultural region in Northern Europe, as well as the Arctic Ocean, Arctic and Atlantic Ocean, North Atlantic oceans. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous administrative division, autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland. The Nordic countries have much in common in their way of life, History of Scandinavia, history, religion and Nordic model, social and economic model. They have a long history of political unions and other close relations but do not form a singular state or federation today. The Scandinavism, Scandinavist movement sought to unite Denmark, Norway and Sweden into one country in the 19th century. With the dissolution of the union between Norway and Sweden (Norwegian independence), the independence of Finland in the early 20th century and the 1944 Icelandic constitution ...

Apomixis
In botany, apomixis is asexual development of seed or embryo without fertilization. However, other definitions include replacement of the seed by a plantlet or replacement of the flower by bulbils. Apomictically produced offspring are genetically identical to the parent plant, except in nonrecurrent apomixis. Its etymology is Greek for "away from" + "mixing". Normal asexual reproduction of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis. In contrast to parthenocarpy, which involves seedless fruit formation without fertilization, apomictic fruits have viable seeds containing a proper embryo, with asexual origin. In flowering plants, the term "apomixis" is used in a restricted sense to mean agamospermy, i.e. clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Hedlundia Hybrida
''Hedlundia hybrida'' (formerly ''Sorbus hybrida''), the Swedish service-tree, Finnish whitebeam, or oakleaf mountain ash, is a species of whitebeam native to Norway, eastern Sweden, south-western Finland, and locally in Latvia. Description ''Hedlundia hybrida'' is a medium-sized deciduous tree growing to tall with a stout trunk up to in diameter, and grey bark. The crown is columnar or conic in young trees, becoming rounded with age, with branches angled upwards. The leaves are green above, and densely hairy with white hairs beneath. long and broad, the leaves are lobed, with six to nine oval lobes on each side of the leaf. These lobes are broadest near the base with the two basal pairs of lobes cut right to the midrib as separate leaflets, rounded at the apex, with finely serrated margins. The autumn colour is dull rusty brown. The flowers are in diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs in diameter in late spring. The f ...

Aria Edulis
''Aria edulis'', the whitebeam or common whitebeam, is a species of deciduous tree in the family ''Rosaceae''. The tree often forms new shoots around the trunk. Typically compact and domed, the plant has a few upswept branches and the leaves have an almost-white underside. The plant sexuality, hermaphrodite cream-white flowers appear in May, are insect pollinated, and go on to produce scarlet berries, which are often eaten by birds. It is native to most of Europe as well as North Africa (Algeria, Morocco, Tunisia) and temperate Asia (Eastern Anatolia Region, Eastern Turkey, Armenia, Georgia). It generally favours dry limestone and chalk soils. The cultivars ''A. edulis'' 'Lutescens', with very whitish-green early leaves, and ''A. edulis'' 'Majestica', with large leaves, have both gained the Royal Horticultural Society's Award of Garden Merit. The berries are edible when overripe (Bletting, bletted). File:Weilburg - Tiergarten - Mehlbeere.jpg, Tree References Sorbus ...

Torminalis Glaberrima
''Torminalis'' is a genus of plants in the rose family, Rosaceae. The genus was formerly included within the genus ''Sorbus'' as the section ''Torminaria'', but the simple-leafed species traditionally classified in ''Sorbus'' are now considered to form a separate monophyletic group. It is monotypic, being represented by the single species ''Torminalis glaberrima'', commonly known as wild service tree, chequers, and checker tree. This tree is native to Europe, parts of northern Africa and western Asia. A possible second species in the genus has been identified through DNA analysis, but a new scientific description for it has not yet been written. Description ''Torminalis glaberrima'' is a medium-sized deciduous tree growing to about 30 m (100 ft) tall, with a trunk up to 1.3 m in diameter. The bark is smooth and grey when young, becoming scaly and flaking away in squarish plates to reveal darker brown layers when about 30 years old. Young twigs are lightly hairy, quickly becomin ...

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (, also ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas. A recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The plant is frost hardy and colonizes disrupted and inacces ...

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
