What is "eucalyptus"

Bloodwood \Blood"wood\, n. (Bot.) A tree having the wood or the sap of the color of blood.

Note: Norfolk Island bloodwood is a euphorbiaceous tree ( Baloghia lucida), from which the sap is collected for use as a plant. Various other trees have the name, chiefly on account of the color of the wood, as Gordonia H[ae]matoxylon of Jamaica, and several species of Australian Eucalyptus; also the true logwood ( H[ae]matoxylon campechianum).

Eucalyptus \Eu`ca*lyp"tus\, n. [NL., from Gr. e'y^ well, good + ? covered. The buds of Eucalyptus have a hemispherical or conical covering, which falls off at anthesis.] (Bot.) A myrtaceous genus of trees, mostly Australian. Many of them grow to an immense height, one or two species exceeding the height even of the California Sequoia.

Syn: eucalyptus tree, gum tree, eucalypt. [1913 Webster]

Note: They have rigid, entire leaves with one edge turned toward the zenith. Most of them secrete resinous gums, whence they called gum trees, and their timber is of great value. Eucalyptus Globulus is the blue gum; E. gigantea, the stringy bark: E. amygdalina, the peppermint tree. E. Gunnii, the Tasmanian cider tree, yields a refreshing drink from wounds made in the bark in the spring. Other species yield oils, tars, acids, dyes and tans. It is said that miasmatic valleys in Algeria and Portugal, and a part of the unhealthy Roman Campagna, have been made more salubrious by planting groves of these trees.

Eucalyptus L'Heritier 1789 is a diverse genus of flowering trees and shrubs (including a distinct group with a multiple-stem mallee growth habit) in the myrtle family, Myrtaceae. Members of the genus dominate the tree flora of Australia. There are more than 700 species of eucalyptus and most are native to Australia, and a very small number are found in adjacent areas of New Guinea and Indonesia. One species, Eucalyptus deglupta, ranges as far north as the Philippines. Only 15 species occur outside Australia, with just nine of these not occurring in Australia. Species of eucalyptus are cultivated widely in the tropical and temperate world, including the Americas, Europe, Africa, the Mediterranean Basin, the Middle East, China, and the Indian subcontinent.

Eucalyptus is one of three similar genera that are commonly referred to as " eucalypts", the others being Corymbia and Angophora. Many species, though by no means all, are known as gum trees because they exude copious kino from any break in the bark (e.g., scribbly gum). The generic name is derived from the Greek words ευ (eu) "well" and καλύπτω (kalýpto) "to cover", referring to the operculum on the calyx that initially conceals the flower.

Some eucalyptus species have attracted attention from horticulturists, global development researchers, and environmentalists because of desirable traits such as being fast-growing sources of wood, producing oil that can be used for cleaning and as a natural insecticide, or an ability to be used to drain swamps and thereby reduce the risk of malaria. Eucalyptus oil finds many uses like in aromatherapy, as a cure for joint pains. Eucalyptus trees show allelopathic effects; they release compounds which inhibit other plant species from growing nearby. Outside their natural ranges, eucalypts are both lauded for their beneficial economic impact on poor populations and criticised for being "water-guzzling" aliens, leading to controversy over their total impact.

On warm days, eucalyptus forests are sometimes shrouded in a smog-like mist of vaporised volatile organic compounds ( terpenoids); the Australian Blue Mountains take their name from the haze.

Eucalyptus is a 1998 novel by Australian novelist Murray Bail. The book won the 1999 Miles Franklin Award and the 1999 Commonwealth Writers' Prize.

Eucalyptus is a post-hardcore album by the San Diego, California band Pitchfork, released in 1990 by Nemesis Records and re-released in 2003 by Swami Records. It is the band's only full-length album. It was produced by guitarist John Reis and its artwork was created by singer Rick Froberg, who at the time used the stage name Rick Fork.

The album was originally released as an LP in limited numbers and soon went out of print. In 2003 Reis re-released it in CD format on his record label Swami Records, including the tracks from the band's Saturn Outhouse 7" as well. This is the only version currently available.

Eucalyptus is a diverse genus of flowering trees in the myrtle family, Myrtaceae.

Eucalyptus may also refer to:

• Eucalyptus (album), an album by Pitchfork
• Eucalyptus (novel), a novel by Murray Bail
• Eucalyptus (software), computer software for cloud computing

Eucalyptus is free and open-source computer software for building Amazon Web Services (AWS)-compatible private and hybrid cloud computing environments marketed by the company Eucalyptus Systems. Eucalyptus is the acronym for Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems. Eucalyptus enables pooling compute, storage, and network resources that can be dynamically scaled up or down as application workloads change. Eucalyptus Systems announced a formal agreement with AWS in March 2012 to maintain compatibility. Mårten Mickos was the CEO of Eucalyptus. In September 2014, Eucalyptus was acquired by Hewlett-Packard.

Eucalyptus is a station on the San Francisco Municipal Railway light rail network's M Ocean View line. It is located in the Merced Manor neighborhood. It is located in the Merced Manor neighborhood in a special rail-only right of way, as the M train cuts through a small designated path to avoid several crowded intersections where Sloat and Ocean Avenues meet California Route 1.
