Dendrosenecio Johnstonii
''Dendrosenecio johnstonii'', formerly ''Senecio johnstonii'', is a species of giant groundsel found in the middle altitudes of Mount Kilimanjaro in Africa. A recent botanical reclassification split off some species formerly in ''Senecio'', putting the giant groundsels in the new genus ''Dendrosenecio''. It also redefined the former species ''Senecio cottonii'', as a subspecies of ''Dendrosenecio johnstonii''. Both genera are in the family ''Asteraceae''. The giant grounsels of the genus ''Dendrosenecio'' evolved, about a million years ago, from a ''Senecio'' that established itself on Mount Kilimanjaro, with those that survived adapting into ''Dendrosenecio kilimanjari''. As it moved down the mountain, the adaptations necessary for the new environment created the new species, ''Dendrosenecio johnstonii''. Various subspecies are found on other mountains. Description ''Dendrosenecio johnstonii'' can be up to 10 meters tall, and grow to 40 centimeters (17 inches) or more in diameter ...

Daniel Oliver (botanist)
Daniel Oliver, FRS (6 February 1830, Newcastle upon Tyne – 21 December 1916) was an English botanist. He was Librarian of the Herbarium, Royal Botanic Gardens, Kew from 1860–1890 and Keeper there from 1864–1890, and Professor of Botany at University College, London from 1861–1888. In 1864, while at UCL, he published ''Lessons in Elementary Biology'', based upon material left in manuscript by John Stevens Henslow, and illustrated by Henslow's daughter, Anne Henslow Barnard of Cheltenham. With a second edition in 1869 and a third in 1878 this book was reprinted until at least 1891. Oliver regarded this book as suitable for use in schools and for young people remote from the classroom and laboratory. He was elected a member of the Linnean Society, awarded their Gold Medal in 1893, and awarded a Royal Medal by the Royal Society in 1884. He married in 1861 and was the father of two daughters and a son, Francis Wall Oliver. In 1895, botanist Tiegh published '' Oliverella'', a ...

Cordillera De Mérida
The Cordillera de Mérida is a series of mountain ranges, or massif, in northwestern Venezuela. The Cordillera de Mérida is a northeastern extension of the Andes Mountains and the most important branch of the Venezuelan Andes. The ranges run southwest–northeast between the Venezuelan-Colombian border and the Venezuelan Coastal Ranges. The Táchira depression separates the Cordillera de Mérida from the Cordillera Oriental, which forms the Colombia-Venezuela border. The ranges runs from southwest to northeast and parts lie within each of the following states: Táchira, Mérida, Barinas, Trujillo, Portuguesa and Lara. The southeastern slopes are drained by tributaries of the Orinoco River, while the streams that drain the northwestern slopes empty into Lake Maracaibo. At the northeast tip of the massif lies the town of Barquisimeto and the headwaters of the River Cojedes. In the centre of the massif is the city of Mérida. Two ranges of peaks lie on either side of the city, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, Herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many Plant stem, stems. T ...

Heath (habitat)
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moorland
Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland, nowadays, generally means uncultivated hill land (such as Dartmoor in South West England), but also includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath, although experts disagree on what precisely distinguishes these types of vegetation. Generally, moor refers to highland and high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats mostly occur in tropical Africa, northern and western Europe, and neotropical South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland also bears a relationship to tundra (where the subsoil is permafros ...

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Fumarole
A fumarole (or fumerole) is a vent in the surface of the Earth or other rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcanic activity, but fumarole activity can also precede a volcanic eruption and has been used for eruption prediction. Most fumaroles die down within a few days or weeks of the end of an eruption, but a few are persistent, lasting for decades or longer. An area containing fumaroles is known as a fumarole field. The predominant vapor emitted by fumaroles is steam, formed by the circulation of groundwater through heated rock. This is typically accompanied by volcanic gases given off by magma cooling deep below the surface. These volcanic gases include sulfur compounds, such as various sulfur oxides and hydrogen sulfide, and sometimes hydrogen chloride, hydrogen fluoride, and other gases. A fumarole that emits significant sulfur compounds is some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helichrysum Newii
The genus ''Helichrysum'' consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is ''Helichrysum orientale''. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Anicent Greek words (helios, sun) and (, gold). It occurs in Africa (with 244 species in South Africa), Madagascar, Australasia and Eurasia. The plants may be annuals, herbaceous perennials or shrubs, growing to a height of . The genus was a wastebasket taxon, and many of its members have been reclassified in smaller genera, most notably the Everlastings, now in the genus ''Xerochrysum''. Their leaves are oblong to lanceolate. They are flat and pubescent on both sides. The bristles of the pappus are scabrous, barbellate, or plumose. The receptacle (''base of the flower head'') is often smooth, with a fringed margin, or honey-combed, and resemble daisies. They may be in almost all colors, except blue. There are man ...
