	Harrisia Regelii ''Harrisia regelii'' is a species of cactus endemic Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsew ... to Argentina and Uruguay. Description ''Harrisia regelii'' grows bushy, scrambling, upright, sometimes arched or prostrate, with green stems that have 4-5 tuberculate ribs. Plants have 1–4 spines, needle-like, initially reddish to almost white thorns later turn gray with a black tip. The individual central spine is 1 to 2 centimeters long. The flowers reach a length of up to 9–22 centimeters with reddish hairs on the buds, spineless and pale green sepals. The spherical, slightly bumpy red fruits have a few scales. Distribution Plants are found growing from Argentina (Santa Fé, Entre Ríos) to Uruguay. References External links * * {{Taxonbar regelii Endemic flora of Arg ...

picture info	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, ...

picture info	Endemic Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

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.
