Hedera Algeriensis
''Hedera algeriensis'', the Algerian ivy, is a species of evergreen ivy native to the North African coast, including coastal mountains in Algeria.Verhaeghe, P. 2004. Clef des plantes sarmenteuses rustiques en Belgique. ''Taxonomania'' 11:1-26 Description It is a vigorous, large evergreen climber, self-clinging by aerial roots. The stems are reddish, partly decorated with stellate hairs or scales, reddish-starred with about 15 rays. The leaves are alternate and simple. As in other ''Hedera'' species, the fertile branches have stiff stems with leaves having usually fewer lobes compared to the sterile (juvenile) stems. The main part of the leaf (the lamina) is oval-rhombic, 12–20 cm by 5–12 cm on flowering branches and coarsely toothed or slightly lobed (3-5 lobes) on the sterile stems. The inflorescence is a cluster of 13-15 pubescent flowers. Small flowers in umbels develop only on the fertile stems or branches. The plant contains the glycoside hederagenin, mostly ...

Shirley Hibberd
James Shirley Hibberd (1825 – 16 November 1890) was one of the most popular and successful gardening writers of the Victorian era. He was a best-selling editor of three gardening magazines, including '' Amateur Gardening'', the only 19th-century gardening magazine still being published today. He wrote over a dozen books on gardening and several more on natural history and related subjects. He promoted town gardening, aquariums, bee-keeping, vegetarianism, water recycling, environmental conservation and the prevention of cruelty to animals and birds, all before they were taken up as 'causes' in the twentieth century. Most important of all, he taught and promoted amateur gardening, before it was acceptable among the gardening establishment, and helped to found the whole consumer industry in amateur gardening that we have today. Early life Shirley Hibberd was born in Mile End Old Town, now part of Stepney, in east London, England. His parentage is obscure but it is believed ...

Mediterranean Area
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea.

Hedera
''Hedera'', commonly called ivy (plural ivies), is a genus of 12–15 species of evergreen climbing or ground-creeping woody plants in the family Araliaceae, native to western, central and southern Europe, Macaronesia, northwestern Africa and across central-southern Asia east to Japan and Taiwan. Description On level ground they remain creeping, not exceeding 5–20 cm height, but on suitable surfaces for climbing, including trees, natural rock outcrops or man-made structures such as quarry rock faces or built masonry and wooden structures, they can climb to at least 30 m above the ground. Ivies have two leaf types, with palmately lobed juvenile leaves on creeping and climbing stems and unlobed cordate adult leaves on fertile flowering stems exposed to full sun, usually high in the crowns of trees or the tops of rock faces, from 2 m or more above ground. The juvenile and adult shoots also differ, the former being slender, flexible and scrambling or climbing with small ae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embankment (transportation)
A road, railway line, or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain, the alternatives being either to have an unacceptable change in level or detour to follow a contour. A cutting is used for the same purpose where the land is originally higher than required. Materials Embankments are often constructed using material obtained from a cutting. Embankments need to be constructed using non-aerated and waterproofed, compacted (or entirely non-porous) material to provide adequate support to the formation and a long-term level surface with stability. An example material for road embankment building is sand-bentonite mixture often used as a protective to protect underground utility cables and pipelines. Intersection of embankments To intersect an embankment without a high flyover, a series of tunnels can consist of a section of high tensile strength viaduct (typically built of ...

Hedera Iberica
''Hedera iberica'' is a species of ivy (genus ''Hedera'') which is native to the western Iberian peninsula (Portugal and southwest Spain), and northern Morocco. It was formerly classified as a sub-species named ''Hedera maderensis iberica'' in ''Hedera maderensis'' (K. Koch ex A. Rutherf). The Iberian subspecies was subsequently classified as a distinct species. It grows on slopes, rock, soil, trunks of trees. It is a climbing perennial shrub or bush with aerial roots. Stems are green or greenish-brown, sometimes tinged with red or purple. This plant has broad leathery leaves, 2 to 8.5 inches long, with 1-5 small lobes, regular in size and shape. The flowers of ''Hedera iberica'' are small, greenish-yellow, gathered in large numbers in umbels, and the fruits are globular and black when ripe. This plant flowers from April to December. Over time it was cultivated in gardens and used in floral arrangements. It is an evergreen climbing plant, growing to 20–30 meters high wher ...

Hedera Maroccana
''Hedera maroccana'', the Moroccan ivy, is a species of ivy (genus ''Hedera'') which is native to the Atlantic coast in northern Africa. It is an evergreen climbing plant, growing to 20–30 m high where suitable surfaces (trees, cliffs, walls) are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established a good bit faster than the related ''Hedera hibernica'' and ''Hedera helix''. The genus name ''Hedera'' is the classical Latin name for ivy. Maroccana is the Latin patronymic of Morocco, where the species was first described. It is quite common in the Canary islands and lives in slopes rock, soil, trunks of trees especially in Laurel forests dominated by ''Apollonias''. The flowers of ''Hedera maroccana'' are small, greenish, gathered in large numbers in umbels, and the fruits are globular and black when ripe. Stems a ...

Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the ''International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity rich ecosystems in the world with a large amount of species directly or indirectly depending on them. Other moss forests include black spruce/feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses including ''Hylocomium splendens'', ''Pleurozium schreberi'' and ''Ptil ...

Hedera Cypria
''Hedera cypria'', is a species of Ivy (genus ''Hedera'') which is endemic to the island of Cyprus. It is an evergreen climbing plant, growing slowly to 20–30 m high where suitable surfaces are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. It is more common at higher altitudes in rocky, shadowy riverine forest, over 400–650 m. In its natural habitat it can be distinguished easily from ''Hedera helix'' subsp. ''poetarum'', also present, because the latter has yellow fruits, while ''Hedera cypria'' is always black-fruited. ''Hedera cypria'' does not resemble any other ivy into such a unique white patterns conspicuous grey veining, red stemmed. It is an attractive robust plant, growing slowly. It has alternate and small to medium ovate leaves, with a long petiole; there are two types of leaves, palmately five-lobed juvenile leaves on creeping and climbing stems, and unlobed la ...
