Weinmannia Pinnata
''Weinmannia pinnata'', commonly known as the bastard briziletto, is a species of tree in the family Cunoniaceae. It is native to Mexico, Central America, South America and the West Indies. It typically grows in wet habitats at high altitudes, and is one of the species found in dwarf forests perpetually wreathed in clouds. Description ''Weinmannia pinnata'' is a large shrub some tall which sometimes grows into a small tree. The trunk can reach in diameter and the bark exudes an astringent gum. The pinnate leaves are up to long and are stalkless. They are arranged in opposite pairs and have a winged midrib. The nine to twenty leaflets are oval, have serrated margins and rusty-brown hairs on the underside. The small flowers are in spikes similar to those of the bottlebrush; the buds are tinged pink and the flowers are white with pink centres. The fruits are dry and red, and divided in two parts. They are tipped by the remains of the long style. Distribution and habitat In Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cunoniaceae
Cunoniaceae is a family of 27 Genus, genera and about 335 species of woody plants in the order Oxalidales, mostly found in the tropical and wet temperate regions of the Southern Hemisphere. The greatest diversity of genera are in Australia and Tasmania (15 genera), New Guinea (9 genera), and New Caledonia (7 genera). The family is also present in Central America, South America, the Caribbean, Malesia, the islands of the South Pacific, Madagascar and surrounding islands. the family is absent from mainland Asia except from Peninsular Malaysia, and almost absent from mainland Africa apart from two species from Southern Africa (''Cunonia capensis'', ''Platylophus trifoliatus''). Several of the genera have remarkable disjunct ranges, found on more than one continent, e.g. ''Cunonia'' (Southern Africa & New Caledonia), ''Eucryphia'' (Australia & South America) ''Weinmannia'' (America and the Mascarenes). The family includes trees and shrubs; most are evergreen but a few are deciduous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dwarf Forest
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal temperate and montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines. High-elevation tropical dwarf forest High-elevation tropical locations in cloud forests contain mossy wet elfin forests due to high-elevation precipitation. These regions are characterized by low rainfall, with most of the wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callistemon
''Callistemon'' is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations. Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus. Description ''Callistemon'' species have commonly been referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are mostly found in the more temperate regions of Australia, especially along the east coast and typically favour moist conditions so when planted in gardens thrive on regular watering. However, two species are found in Tasmania and several others in the south-west of Western Australia. At least some species are drought-resistant and some are used in ornamental landscaping elsewhere in the world. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sierra De Luquillo
The Sierra de Luquillo is a mountain range located in the northeastern part of Puerto Rico. Also known as the Luquillo Mountains, these are steep-sided, densely-forested mountains rising to elevations of around , the highest point being the summit of El Toro, closely followed by that of Pico El Yunque. Geography The mountains of the Sierra de Luquillo were formed by tectonic activity some 37 to 28 million years ago, the island being on the junction between the North American Plate and the Caribbean Plate. The main rock types are pyroclastic rocks, quartzdiorite and contact metamorphic hornfels, with some outcrops of alluvium, basalt and mafic rocks. Nine rivers have their sources in the mountains, flowing downward through steep, rocky and boulder-strewed channels before reach the coastal plains. Easterly winds off the Atlantic Ocean rise and cool as they pass over the mountains, and the ensuing heavy precipitation brings an annual rainfall of on the ridge. The lower slopes a ...

Weinmannia
''Weinmannia'' is a genus of trees and shrubs in the family Cunoniaceae. It is the largest genus of the family with about 150 species. It is also the most widespread genus, occurring in Central and South America including the Caribbean, Madagascar and surrounding islands, Malesia and the islands of the South Pacific. It is absent from mainland Africa and Australia, but some fossils have been attributed to ''Weinmannia'' in Australia. Leaves are simple or pinnate, with a margin usually toothed, and interpetiolar stipules. Flowers are bisexual, white, arranged in racemes. The fruit is a capsule opening vertically from the top to the base. Seeds hairy without wings. Taxonomy The genus has been divided into five sections: * ''Fasciculata'' (mostly Malesia, from Sumatra to Fiji) * ''Inspersa'' (Madagascar) * ''Leiospermum'' (mostly Pacific, from Bismarck archipelago to the Marquesas) * ''Spicata'' (Madagascar and Comores) * ''Weinmannia'' (Central and South America, Mascarenes) A phy ...

Trees Of Mexico
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South America
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
