Xanthostemon Arenarius
''Xanthostemon arenarius'' is a species of tree in the myrtle family Myrtaceae that is endemic to tropical north-eastern Queensland, Australia. Description The tree usually grows to about 5–6 m in height, though is occasionally found as an emergent up to 20 m. The bark is plated and hard, grey to greyish brown. The spirally arranged leaves are about 5–9 cm long by 2–4.5 cm wide. The flowers are yellow, with the inflorescences crowded at the ends of seasonal growth. The ovoid fruits are about 10–14 mm in diameter, containing flat seeds 4.25–6 mm long. Distribution and habitat The species is known only from a restricted locality on the east coast of Queensland's Cape York Peninsula, north of Cooktown, in the Cape Bedford to Cape Flattery area. It grows on the grey or white sandy soils of Quaternary dunes, in closed forest dominated by ''Asteromyrtus angustifolia'' or ''Araucaria ''Araucaria'' (; original pronunciation: .ɾawˈka. ...

Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciat ...

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] |

Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

Cape Flattery (Queensland)
Cape Flattery is a cape in northern Queensland approximately north of Cooktown, Queensland. The headland was named by James Cook on 10 August 1770 as he charted the eastern Australian coast. Silica mine Cape Flattery is the location of the world's biggest silica mine. The mine was established in 1967 and was severely damaged by Cyclone Ita in 2014.

Quaternary
The Quaternary ( ) is the current and most recent of the three period (geology), periods of the Cenozoic era (geology), Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino (geologist), Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ord ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''Erg (landform), ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the wiktionary:stoss, stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in othe ...
