Diospyros Leucomelas
''Diospyros leucomelas'' (marble ebony, bois d'ebene marbre or bois d'ebene a veines) is a species of tree endemic to Mauritius. Description This low, multi-stemmed tree species resembles the related species ''Diospyros egrettarum'' (and less so ''Diospyros revaughanii'') in its dark, rectangular, leathery leaves, rounded leaf-base, very short petiole, and short fruits. ''Diospyros leucomelas'' can be distinguished by the red midribs of its leaves though, which remain into adulthood and become especially prominent on the leaf undersides. Distribution and habitat Like ''Diospyros egrettarum'', it occurred in coastal and dry forest, all around Mauritius, and was especially common along the eastern coast. In fact, these two species were the only two primarily coastal or lowland species of ''Ebony Ebony is a dense black/brown hardwood, coming from several species in the genus ''Diospyros'', which also contains the persimmons. Unlike most woods, ebony is dense enough to sink i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diospyros Egrettarum
''Diospyros egrettarum'' is a species of tree endemic to Mauritius Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It incl ... and was once a dominant species throughout dry and coastal forests. Due to harvests for timber and firewood in the past the species was reduced to fewer than 10 individuals on the main land. The only viable population remained on Île aux Aigrettes, a coral island off the east coast, where it was able to survive thanks to protective measures, such as the eradication of exotic plants and rats. The tree is named after this Island. Morphology Most characteristic feature of the tree is the white bark of the often multistemmed trees. They form rectangular leathery leaves of dark colour with thick waxy cuticles. This species closest relative is ''Diospyros leucomelas'' ( ...

Diospyros Revaughanii
''Diospyros revaughanii'' is a rare species of tree in the family Ebenaceae (ebony). The tree is one of several species of ebony tree which are endemic to the island of Mauritius, in the western Indian Ocean. Description A short, evergreen, shrubby tree, which reaches 4 meters in height. The large, thick leaves have a circular to slightly rectangular shape. They are densely packed along the stems, and attach directly to the tree without any leaf stalks. This is the distinctive feature which can be used to distinguish this tree from the other ebony species of Mauritius. Like many Mauritian plants, it is heterophyllous and the foliage of juvenile plants is entirely different to that of adult plants. This adaptation is due to the grazing of the (now extinct) giant tortoises of the island. The leaves of young ''D. revaughanii'' are therefore longer, thinner, oblong and have petioles (stalks). Its trunk is thin and it branches from quite low down. Branches and twigs form at an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diospyros
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as " God's pear" and " Jove's fire". The genus is a large one a ...
