Couma Macrocarpa
''Couma macrocarpa'', known by the common names leche caspi, leche huayo, sorva (a name it shares with its smaller relative ''Couma utilis''), and cow tree, is a species of tropical plant native to tropical, humid Central and South America from Belize to Bolivia. Ideal environmental conditions for ''Couma macrocarpa'' are: * average annual maximum temperature of 25.1 °C * average annual minimum temperature of 17.2 °C * average annual precipitation: 3,419 mm. (max) and 1,020 mm (min). It is found at variable altitudes from sea level to 1000 metres, in non-flooding areas with good drainage and in soils of good fertility. It adapts well to ultisols and oxisols and can tolerate long dry periods. In the Peruvian Amazon it is cultivated for its latex.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. 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 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. phylogenetic analysis should c ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and Americas, American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found List of subfamilies and genera of Apocynaceae, here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial plant, perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arr ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern Subregion#Americas, subregion of a single continent called Americas, America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territory, dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one administrative division, internal territory: French Guiana. In addition, the ABC islands (Leeward Antilles), ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Asce ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Couma Utilis
''Couma utilis'', called the milk tree, sorvinha, sorveira, sorva (a name it shares with its larger relative '' Couma macrocarpa''), and sorva-pequena, is a species of flowering plant in the subfamily Rauvolfioideae, native to the Orinoco and Amazon basins of South America. It is thought that ''C.utilis'' was on the verge of being domesticated by indigenous Amazonian peoples prior to the arrival of Europeans in the New World. Description ''Couma utilis'' is usually a tree tall, and occasionally a bush reaching only . Its bark is smooth and dark brown. When cut it exudes large quantities of white latex. Its root system usually consists of a taproot reaching down , more in softer soils, and superficial roots that extend far beyond the dripline. Its simple, entire leaves are oppositely arranged, with three leaves at branch termini. Leaf blades are elliptic, wide and long, with rounded to subobtuse apices. Leaf bases are cuneate and extend decurrently onto the petiole. They have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
