La Oroya
La Oroya is a city on the River Mantaro in central Peru. It is situated on the Andes some 176 km east-north-east of the national capital, Lima, and is capital of the Yauli Province. La Oroya is the location of a smelting operation that earned the town a place on the Blacksmith Institute's 2007 report on "The World's Worst Polluted Places". History In 1533, the Spanish established a small settlement and started small-scale mining for precious metals in the area, but isolation and transport difficulties hindered extraction. At the time of the War of Independence, the area's strategic position made it a center of guerrilla activity; one of the decisive battles of the war, Chacamarca (Junin), took place nearby, and Simón Bolívar passed through the town after the battle. In 1861, the settlement was named San Jeronímo de Callapampa and in 1893 it became La Oroya. In 1925, La Oroya was designated the capital of the Yauli province and finally, in 1942, it was elevated to ci ...

Cactoideae
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. *Blossfeldieae **''Blossfeldia'' * Browningieae **''Armatocereus'' – ''Browningia'' – ''Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – '' Astrophytum'' – ''Aztekium'' – ''Coryphantha'' – '' Cumarinia'' – ''Echino ...

Trichocereeae
Trichocereeae is a tribe of cactus that are particular to South America. There are 25 recognized genera in this tribe. Description Arborescent to shrubby, Trichocereeae normally form unsegmented, spherical to columnar stems that are usually ribbed, tuberculate, or ribbed-warty. The small to fairly large, regular or bilaterally symmetrical flowers appear laterally or below the apex and open day or night. The flower cup is scaled or covered with hair. The fruits are fleshy to berry-like and sometimes burst open lengthwise. They contain small to medium-sized seeds that vary in shape. Hilum and micropyle of seeds are fused to united. Appendages are usually absent. A strophic is present in some. Genera *'' Acanthocalycium'' *'' Arthrocereus'' *'' Brachycereus'' *'' Cleistocactus'' *''Denmoza'' *''Discocactus'' *''Echinopsis'' *'' Espostoa'' *'' Espostoopsis'' *'' Facheiroa'' *''Gymnocalycium'' *'' Haageocereus'' *'' Harrisia'' *'' Leocereus'' *''Matucana'' *'' Mila'' *'' Oreocereus'' ...

Cacti Of South America
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

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 ...
