Friedrich Ernst Ludwig Von Fischer
Friedrich Ernst Ludwig Fischer (20 February 1782, Halberstadt – 17 June 1854) was a Russian botanist, born in the Holy Roman Empire. He was director of the St Petersburg botanical garden from 1823 to 1850. In 1804 he obtained his medical doctorate from the University of Halle, afterwards working as director of Count Razumoffsky's botanical garden in Gorenki (near Moscow). In 1808 he produced a catalogue of plants of the garden. In 1823, he was appointed director of the imperial botanical garden in St. Petersburg by Alexander I of Russia, Alexander I. Here, he was involved with establishing a herbarium and library, as well as the planning of numerous scientific expeditions into the interior of Russia. During his final years, he served as a medical councillor for the Ministry of the Interior. In 1815, he was elected a corresponding member of the Royal Swedish Academy of Sciences. In 1841, his status was changed to that of foreign member. Selected works * ''Catalogue du Jardin ... [...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] |
Flora Of Turkey
The flora of Turkey consists of almost 10,000 species of plants, as well as a number of fungi and algae. Around 32% of Turkey's plants are found only in the country. One reason for the high proportion of endemics is that Anatolia is both mountainous and quite fragmented. The country is divided into three main floristic areas: the Mediterranean, Euro-Siberian, and Irano-Tranian area. The flora of the European part of Turkey is similar to that of adjoining Greece. The ecoregions here include Balkan mixed forests dominated by Oak, oaks, and Aegean and Western Turkey sclerophyllous and mixed forests where some of the main species are oaks, Arbutus unedo, strawberry tree, ''Arbutus andrachne, Greek strawberry tree'', Spartium junceum, Spanish broom and Laurus nobilis, laurel.

Trees Of Western Asia
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Azerbaijan
Flora of Azerbaijan or Vegetation of Azerbaijan refers to the plants, trees and flowers which can be found in Azerbaijan. Azerbaijan has a very rich flora, more than 4,500 species of higher plants have been registered in the country. Due to the unique climate in Azerbaijan, the flora is much richer in the number of species than the flora of the other republics of the South Caucasus. About 66% of the species growing in the whole Caucasus can be found in Azerbaijan. The richness of Azerbaijan's flora and the variety of its vegetation results from the variety and richness of its physical-geographic and natural-historic conditions and from its compound history influenced by the remote floristic regions. The floristic areas of Azerbaijan All types of floristic areas – ancient wood, boreal, plain, xerophytic, desert, Caucasian and accidental – exist in Azerbaijan. The representatives of ancient wood type are widely spread in the Talysh region and the location which is suitable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Armenia
The wildlife of Armenia includes the wild boar, crested porcupine, various lizards, snakes and numerous species of birds and plants. Endangered species in Armenia are the bear, wild goat, Armenian mouflon and the leopard. Fauna Fauna in Armenia is diverse given the country's relatively small size, owing to the varied habitats created by the area's mountainous terrain. Armenia is an important area for migratory animals, about 350 different bird species were recorded in the country. Many of the world's domesticated animals originated in or near Armenia, and the mouflon, the ancestor of domesticated sheep, is present there. Research suggests that about a quarter of the animal species in Armenia are internationally endangered. The mouflon is suffering a great population decline due to poaching and habitat loss, and the Sevan trout, which once made up thirty percent of the fish in Lake Sevan, have virtually disappeared. Southern and south-western Armenia remains the last strongh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1838
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymn ...

Quercus
An oak is a hardwood tree or shrub in the genus ''Quercus'' of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve. Ecologically, oaks are keystone species in habitats from Mediterranean semi-desert to subtropical rainforest. They live in association with many kinds of fungi including truffles. Oaks support more than 950 species of caterpillar, many kinds of gall wasp which form distinctive galls (roundish woody lumps such as the oak apple), and a large number of pests and diseases. Oak leaves and acorns contain enough tannin to be toxic to cattle, but pigs are ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azerbaijan
Azerbaijan, officially the Republic of Azerbaijan, is a Boundaries between the continents, transcontinental and landlocked country at the boundary of West Asia and Eastern Europe. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia's republic of Dagestan to the north, Georgia (country), Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city. The territory of what is now Azerbaijan was ruled first by Caucasian Albania and later by various Persian empires. Until the 19th century, it remained part of Qajar Iran, but the Russo-Persian wars of Russo-Persian War (1804–1813), 1804–1813 and Russo-Persian War (1826–1828), 1826–1828 forced the Qajar Empire to cede its Caucasian territories to the Russian Empire; the treaties of Treaty of Gulistan, Gulistan in 1813 and Treaty of Turkmenchay, Turkmenchay in 1828 defined the border between Russia and Iran.
