Commidendrum Robustum
''Commidendrum robustum'', the Saint Helena gumwood, is a species of tree endemic to Saint Helena, Ascension and Tristan da Cunha.Cairns-Wicks, R. 2003''Commidendrum robustum''.The IUCN Red List of Threatened Species 2003. Downloaded on 16 September 2015. Though it is now comparatively rare, it was once one of the most abundant trees of mid-elevations of the island of Saint Helena in the South Atlantic Ocean. A small tree to 7–8 m, it was cut extensively for fuel in the early years of settlement of the island by the English East India Company. It has given its name to certain placenames on the island such as "Gumwoods". It is one of several species in the endemic genus ''Commidendrum ''Commidendrum'' is a genus of trees and shrubs in the family Asteraceae endemic to the island of Saint Helena in the South Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about .

Commidendrum Rotundifolium
''Commidendrum rotundifolium'', the bastard gumwood, is a species of tree endemic to the island of Saint Helena. It was thought to be extinct, but one last tree was discovered in Horse Pasture in 1982. This tree, long believed to be the last, was destroyed in 1986 by a gale. However seedlings were grown from this tree before it perished. The last of these to survive in cultivation was damaged by gales in 2008 and the survival of the species was in doubt. In December 2009, Lourens Malan, a horticulturist working for the island's conservation department under the Critical Species Recovery Project, discovered a wild tree growing on a cliff. A local team of botanists, conservationists and volunteers commenced an intensive programme of hand pollination and seed collection of the remaining cultivated tree, while protecting it from insects that may cross-pollinate with nearby false gumwoods. Successful fertilisation will occur only if any grains of pollen happen to have mutation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint Helena
Saint Helena () is a British overseas territory located in the South Atlantic Ocean. It is a remote volcanic tropical island west of the coast of south-western Africa, and east of Rio de Janeiro in South America. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. Saint Helena measures about and has a population of 4,439 per the 2021 census. It was named after Helena, mother of Constantine I. It is one of the most remote islands in the world and was uninhabited when discovered by the Portuguese enroute to the Indian subcontinent in 1502. For about four centuries the island was an important stopover for ships from Europe to Asia and back, while sailing around the African continent, until the opening of the Suez canal. St Helena is the United Kingdom's second-oldest overseas territory after Bermuda. Saint Helena is known for being the site of Napoleon's second exile, following his final defeat in 1815. ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technica ...

South Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
