Eryngium Maritimum
''Eryngium maritimum'', the sea holly or sea eryngo, or sea eryngium, is a perennial species of flowering plant in the family Apiaceae and native to most European coastlines. It resembles a plume thistle in appearance on account of its burr-shaped flower. Despite its common name, it is not related to true holly, but is an umbellifer. Etymology ''E. maritimum'' was formally described by Linnaeus in his Species Plantarum I: 233 (1753). The generic name ''Eryngium'' derives from Greek and may have developed from a description of the plant by Theophrastus (300 BC), who referred to it as “Eryngion”, meaning a spiny plant. Alternatively, the name may have derived from the Greek word “eruggarein”, meaning to eructate (belch), since the plant was used to treat various disorders such as trapped gases. The specific epithet ''maritimum'' means “of the sea”. The common English name appears to date from the 16th century. In his 1548 publication ''The Names of Herbes'', the natur ...

Botanical Illustration
Botanical illustration is the art of depicting the form, color, and details of plant species, frequently in watercolor paintings. They must be scientifically accurate but often also have an artistic component and may be printed with a botanical description in books, magazines, and other media or sold as a work of art. Often composed by a botanical illustrator in consultation with a scientific author, their creation requires an understanding of plant morphology and access to specimens and references. Typical illustrations are in watercolour, but may also be in oils, ink or pencil, or a combination of these. The image may be life size or not, the scale is often shown, and may show the habit and habitat of the plant, the upper and reverse sides of leaves, and details of flowers, bud, seed and root system. Botanical illustration is sometimes used as a Biological type, type for attribution of a botanical name to a taxon. The inability of botanists to conserve certain dried specimen ...

Bracteole
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marram Grass
''Ammophila'' (synonymous with ''Psamma'' P. Beauv.) is a genus of flowering plants consisting of two or three very similar species of grasses. The common names for these grasses include marram grass, bent grass, and beachgrass. These grasses are found almost exclusively on the first line of coastal sand dunes. Their extensive systems of creeping underground stems or rhizomes allow them to thrive under conditions of shifting sands and high winds, and to help stabilize and prevent coastal erosion. ''Ammophila'' species are native to the coasts of the North Atlantic Ocean where they are usually the dominant species on sand dunes. Their native range includes few inland regions, with the Great Lakes of North America being the main exception. The genus name ''Ammophila'' originates from the Greek words ἄμμος (''ámmos''), meaning "sand", and φίλος (''philos''), meaning "friend". The ''Ammophila'' grasses are widely known as examples of xerophytes, plants that can withstand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gotland
Gotland (, ; ''Gutland'' in Gutnish), also historically spelled Gottland or Gothland (), is Sweden's largest island. It is also a province, county, municipality, and diocese. The province includes the islands of Fårö and Gotska Sandön to the north, as well as the Karlsö Islands ( Lilla and Stora) to the west. The population is 61,001, of which about 23,600 live in Visby, the main town. Outside Visby, there are minor settlements and a mainly rural population. The island of Gotland and the other areas of the province of Gotland make up less than one percent of Sweden's total land area. The county formed by the archipelago is the second smallest by area and is the least populated in Sweden. In spite of the small size due to its narrow width, the driving distance between the furthermost points of the populated islands is about . Gotland is a fully integrated part of Sweden with no particular autonomy, unlike several other offshore island groups in Europe. Historically there was ...

Skagerrak
The Skagerrak (, , ) is a strait running between the Jutland peninsula of Denmark, the southeast coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea area through the Danish Straits to the Baltic Sea. The Skagerrak contains some of the busiest shipping routes in the world, with vessels from every corner of the globe. It also supports an intensive fishing industry. The ecosystem is strained and negatively affected by direct human activities. Oslo and Gothenburg are the only large cities in the Skagerrak region. Name The meaning of ''Skagerrak'' is most likely the Skagen Channel/Strait. Skagen is a town near the northern cape of Denmark (The Skaw). ''Rak'' means 'straight waterway' (compare the Damrak in Amsterdam); it is cognate with '' reach''.Nudansk Ordbog (1993), 15th edition, 2nd reprint, Copenhagen: Politikens Forlag, entry ''Skagerrak''. The ultimate source of this syllable is the Proto-Indo-European root *reg-, 'straight'. ''Rak'' me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azov Sea
The Sea of Azov ( Crimean Tatar: ''Azaq deñizi''; russian: Азовское море, Azovskoye more; uk, Азовське море, Azovs'ke more) is a sea in Eastern Europe connected to the Black Sea by the narrow (about ) Strait of Kerch, and is sometimes regarded as a northern extension of the Black Sea. The sea is bounded by Russia on the east, by Ukraine on the northwest and southwest. The sea is largely affected by the inflow of the Don, Kuban, and other rivers, which bring sand, silt, and shells, which in turn form numerous bays, limans, and narrow spits. Because of these deposits, the sea bottom is relatively smooth and flat with the depth gradually increasing toward the middle. Also, due to the river inflow, water in the sea has low salinity and a high amount of biomass (such as green algae) that affects the water colour. Abundant plankton result in unusually high fish productivity. The sea shores and spits are low; they are rich in vegetation and bird colonies. Th ...

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper, and Don (river), Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the ...
