Matucana
''Matucana'' is a genus of cacti (family Cactaceae), containing approximately 20 species of mostly globular plants. The genus is only known from Peru, mostly along the Marañón River. The first species was discovered near the town of Matucana and described as ''Echinocactus haynii'' by Otto in 1849. ''Matucana'' was erected by Britton & Rose in 1922. The genus ''Eomatucana'' F.Ritter has been brought into synonymy with this genus. Some species are endangered due to collection for the specialist market. Description Low, globose or shortly cylindrical bodies, either solitary or clustering. The flowers are subapical, usually more or less zygomorphic, diurnal, in various colours, but mainly red, yellow or pink. However, a few species, notably ''M. oreodoxa'', have actinomorphic flowers and were placed in a separate genus - ''Eomatucana'' - by F. Ritter. They are reported to flower easily at a young age. Cultivation All members of the genus cannot tolerate too much moistur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Matucana, Peru
Matucana is a town in Central Peru, capital of the Matucana District located in the Huarochirí Province, in the Department of Lima. It's located to the east of Lima at 2,378 m (7,802 ft) above sea level, along the Central Highway ( es, Carretera Central) at km 74. History Matucana was founded in 1647 by Miguel de Castro y García, a descendant of one of Francisco Pizarro's Conquistadores. He discovered gold in the hills outside of Matucana at a site that was once a holy shrine for the Incas. Using Inca slaves to operate the mine, he became very wealthy and eventually returned to live in Lima, Peru. The gold mine was unfortunately buried in a huge avalanche triggered by the devastating Santa Ursula earthquake of October 21, 1756, which also caused great damage to the City of Lima. Society and culture The City of Matucana is a popular destination for eco-tourists, as it has beautiful water falls in the deep valleys outside of the town and plentiful hiking trails. I ...

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'' � ...

Trichocereeae
Trichocereeae is a tribe of cactus that are particular to South America. There are 25 recognized genera in this tribe.

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation.
