Harrisia Divaricata
''Harrisia divaricata'' is a species of cactus endemic to Hispaniola. Description ''Harrisia divaricata'' grows as a shrub up to 1 meter tall with upright, richly branched, slender shoots. There are nine blunt ribs. The four brown central spines are 2 to 2.5 centimeters long. The eight to ten marginal spines are white. The flowers are large and the globose spherical fruits are yellow. Seeds are 1.4–1.65 × 2.05 –2.6 mm. Distribution ''Harrisia divaricata'' is widespread on Hispaniola growing in scrublands and scrub forest at 5-400 meters. Taxonomy The first description as Cactus divaricatus was made in 1785 by Jean-Baptiste de Lamarck. The specific epithet divaricata means 'spread'. Curt Backeberg Curt Backeberg (2 August 1894 in Lüneburg, Germany – 14 January 1966) was a German horticulturist especially known for the collection and classification of cacti.

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, ...

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] |
Hispaniola
Hispaniola (, also ; es, La Española; Latin and french: Hispaniola; ht, Ispayola; tnq, Ayiti or Quisqueya) is an island in the Caribbean that is part of the Greater Antilles. Hispaniola is the most populous island in the West Indies, and the region's second largest in area, after the island of Cuba. The island is divided into two separate nations: the Spanish-speaking Dominican Republic (48,445 km2, 18,705 sq mi) to the east and the French/ Haitian Creole-speaking Haiti (27,750 km2, 10,710 sq mi) to the west. The only other divided island in the Caribbean is Saint Martin, which is shared between France ( Saint Martin) and the Netherlands (Sint Maarten). Hispaniola is the site of one of the first European settlements in the Americas, La Navidad (1492–1493), as well as the first proper town, La Isabela (1493–1500), and the first permanent settlement, the current capital of the Dominican Republic, Santo Domingo (est. 1498). These settlements were founded succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste De Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Muséum n ...

Curt Backeberg
Curt Backeberg (2 August 1894 in Lüneburg, Germany – 14 January 1966) was a German horticulturist especially known for the collection and classification of cacti. Biography He travelled extensively through Central and South America, and published a number of books on cacti, including the six-volume, 4,000-page ''Die Cactaceae'', 1958–1962, and the ''Kakteenlexikon'', first appearing in 1966 and updated posthumously. Although he collected and described many new species and defined a number of new genera, much of his work was based on faulty assumptions about the evolution of cacti and was too focused on geographic distribution; many of his genera have since been reorganized or abandoned. The botanist David Hunt is quoted as saying that he "left a trail of nomenclatural chaos that will probably vex cactus taxonomists for centuries.", p. 98 Nevertheless, his observations regarding the subtle variations among cacti have proven useful for hobbyists, who continue to use many cactu ...

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.

Flora Of Haiti
The wildlife of Haiti is important to the country because of its biodiversity. According to the World Conservation Monitoring Centre, Haiti is considered to be "one of the most biologically significant countries of the West Indies". With an estimated 5,600 plant species on the island of Hispaniola, some of which only occur in Haiti, 36% are considered as endemic to the island. A mountainous area country, it is situated in the western three-eighths of Hispaniola and shares a border with the Dominican Republic. There are nine life zones, from low desert to high cloud forests, as well as four mountain ranges, and hundreds of rivers and streams and the coral reefs in the seas that surround the islands. Issues of environmental damage, expanding population, deforesting and erosion are of concern; less than 2% of the original forest remains on account of deforestation. This degradation is traced from the 17th century to 19th century starting with the French colonization of the Haiti and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
