Nathaniel Lord Britton
Nathaniel Lord Britton (January 15, 1859 – June 25, 1934) was an American botanist and taxonomist who co-founded the New York Botanical Garden in the Bronx, New York. Early life Britton was born in New Dorp in Staten Island, New York to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Club soon after graduation and was a member his entire life. He married Elizabeth Gertrude Knight, a bryologist, on August 27, 1885. They had met when she joined the club and were lifelong collaborators in botanical research. New York Botanical Garden During their honeymoon in 1888, they visited Kew Gardens, which led to his wife proposing a botanical garden for New York at a Torrey Club meeting. Together, they campaigned to bring ... [...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 spin ...

Harrisia (plant)
''Harrisia'' (applecactus and moonlight cactus) is a genus of night blooming 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 in Queensland, Africa, and the U.S. state of Hawaii. The genera ''Eriocereus'' ( A.Berger) Riccob. and ''Roseocereus'' Backeb. have been brought into synonymy with this genus.

Endemism
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Flora Of North America
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
