Gevuina
''Gevuina avellana'', commonly known as the Chilean hazelnut ( in Spanish) or Gevuina hazelnut, is an evergreen tree growing up to 20 meters (65 feet) tall. It is the only species currently classified in the genus ''Gevuina''. It is native to southern Chile and adjacent valleys in Argentina. It is found from sea level to 700 meters (2,300 feet) above sea level. Its distribution extends from 35° to 44° south latitude. The composite leaves are bright green and toothed, and the tree is in flower between July and November. The flowers are very small and beige to whitish, are bisexual and group two by two in long racemes. The fruit is a dark red nut when young and turns black. The peel is woody. It can grow up straight or branched from the soil, making up either a tree or a shrub. The name ''Gevuina'' comes from , the Mapuche Indigenous name for the Chilean hazel. The origin of the Spanish name, ''avellano'' come from the fact the Spanish settlers found the nuts similar to the haz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proteaceae
The Proteaceae form a family (biology), family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genus, genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae (plane trees), Nelumbonaceae (the sacred lotus) and in the recent APG IV system the Sabiaceae, they make up the order Proteales. Well-known Proteaceae genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'', and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''Grevillea'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of ''Gevuina avellana'' on a smaller scale. Etymology The name Proteaceae was adapted by Robert Brown (botanist, born 1773), Robert Brown from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultisol
Ultisol, commonly known as red clay soil, is one of twelve soil orders in the USDA soil taxonomy, United States Department of Agriculture soil taxonomy. The word "Ultisol" is derived from "ultimate", because Ultisols were seen as the ultimate product of continuous weathering of minerals in a humid, temperate climate without new soil formation via glaciation. They are defined as mineral soils which contain no calcareous (Limestone, calcium carbonate containing) material anywhere within the soil, have less than 10% weatherable minerals in the extreme top layer of soil, and have less than 35% base (chemistry), base saturation throughout the soil. Ultisols occur in humid temperate or tropical regions. While the term is usually applied to the red clay soils of the Southern United States, Ultisols are also found in regions of Africa, Asia, Australia and South America. In the World Reference Base for Soil Resources (WRB), most Ultisols are known as Acrisols and Alisols. Some belong to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Fitzroya
''Fitzroya'' is a monotypic genus in the cypress family. The single living species, ''Fitzroya cupressoides'', is a tall, long-lived conifer native to the Andes mountains and coastal regions of southern Chile, and only to the Argentine Andes, where it is an important member of the Valdivian temperate forests. Common names include ''lawal'' (in Mapudungun, Hispanicized as ''lahual''), ''alerce'' (, " larch" in Spanish), and Patagonian cypress. The genus was named in honour of Robert FitzRoy.
