''Harrisia tetracantha'' is a species of cactus found in Bolivia. Description ''Harrisia tetracantha'' grows in a shrub-like to tree-like manner, is usually branched above the ground and reaches heights of up to 3 meters. The blue-green to gray-green shoots have a diameter of up to 6 centimeters. There are eight rounded and tuberous ribs. The single, strong, initially brownish central spine later becomes white to ash-gray. The four to seven white marginal spines have a brown tip. The flowers reach a length of 18 to 22 centimeters. Distribution ''Harrisia tetracantha'' is widespread in the Bolivian departments of Cochabamba, Chuquisaca, Potosi, Santa Cruz and Tarija in dry scrub forest at elevations of 1200–2600 meters. Taxonomy The first description as ''Cereus tetracanthus'' was made in 1855 by J. Labouret. David Richard Hunt placed the species in the genus Harrisia in 1987. Further nomenclature synonyms are ''Eriocereus tetracanthus'' (Labour.) Riccob. (1909), ''Trichocereu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
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, ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Harrisia (plant)
''Harrisia'' (applecactus and moonlight cactus) is a genus of night blooming cactus, cacti native to Argentina, Paraguay, Brazil, Bolivia, Uruguay, the Greater Antilles, the Bahamas, and the U.S. state of Florida. The genus is named after William Harris, an important botanist of Jamaica. There are about 20 species. Harrisia cactus is an exotic invasive species, invasive in Queensland, Africa, and the U.S. state of Hawaii. The genus, genera ''Eriocereus'' (A.Berger) Riccob. and ''Roseocereus'' Backeb. have been brought into synonym (taxonomy), synonymy with this genus.
