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] |

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. It is grown in Loreto, San Martín, Ucayali, Madre de Dios, Huánuco, and Pasco. The sticky white latex is eaten for treating diarrhea and skin ailments. It is used for patching, sealing and to waterproof can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 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 ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...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 opini ...

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 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 here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also 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 arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of a single continent called 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 territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...
