Xanthostemon Formosus
''Xanthostemon formosus'' is a species of tree in the myrtle family Myrtaceae that is endemic to north-eastern Queensland, Australia. Description The species may reach a height of 18 m with a stem diameter of 30 cm. The bark is grey and flaky. The crowded leaves are about 12–22 cm long by 2–4.5 cm wide, forming whorls on the twigs. The flowers are greenish-yellow. The fruits are globular, about 12–20 mm in diameter, containing flat seeds 4–5 mm across. Distribution and habitat Endemic to the wet tropics of north-eastern Queensland, the species is restricted to a few streams between the Daintree River and Cape Tribulation, with an altitudinal range from close to sea level to 100 m. It grows as a rheophyte along rocky or boulder-strewn streams flowing through rainforest. References formosus Pope Formosus (896) was the bishop of Rome and ruler of the Papal States from 6 October 891 until his death on 4 April 896. His reign as ...

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] |

Australian Tropical Rainforest Plants
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which are treated in a separate key called Australian Tropical Rainforest Orchids (see External links section). A key for ferns is under development. RFK is a project initiated by the Australian botanist Bernie Hyland. History The information system had its beginnings when Hyland started working for the Queensland Department of Forestry in the 1960s. It was during this time that he was tasked with the creation of an identification system for rainforest trees, but given no direction as to its format. Having little belief in single-access keys, he began work on creating a multi-access ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Government
The Australian Government, also known as the Commonwealth Government, is the national government of Australia, a federal parliamentary constitutional monarchy. Like other Westminster-style systems of government, the Australian Government is made up of three branches: the executive (the prime minister, the ministers, and government departments), the legislative (the Parliament of Australia), and the judicial. The legislative branch, the federal Parliament, is made up of two chambers: the House of Representatives (lower house) and Senate (upper house). The House of Representatives has 151 members, each representing an individual electoral district of about 165,000 people. The Senate has 76 members: twelve from each of the six states and two each from Australia's internal territories, the Australian Capital Territory and Northern Territory. The Australian monarch, currently King Charles III, is represented by the governor-general. The Australian Government in its exec ...

Wet Tropics Of Queensland
The Wet Tropics of Queensland World Heritage Site consists of approximately 8,940 km2 of Australian wet tropical forests growing along the north-east Queensland portion of the Great Dividing Range. The Wet Tropics of Queensland meets all four of the criteria for natural heritage for selection as a World Heritage Site. World Heritage status was declared in 1988, and on 21 May 2007 the Wet Tropics were added to the Australian National Heritage List. The tropical forests have the highest concentration of primitive flowering plant families in the world. Only Madagascar and New Caledonia, due to their historical isolation, have humid, tropical regions with a comparable level of endemism. The Wet Tropics rainforests are recognised internationally for their ancient ancestry and many unique plants and animals. Many plant and animal species in the Wet Tropics are found nowhere else in the world. The Wet Tropics has the oldest continuously surviving tropical rainforests on earth ...

Daintree River
The Daintree River is a river that rises in the Daintree Rainforest near Cape Tribulation in Far North Queensland, Australia. The river is located about northwest of Cairns in the UNESCO World Heritagelisted Wet Tropics of Queensland. The area is now primarily a tourist attraction. Course and features The river rises on the slopes of the Great Dividing Range within the Daintree National Park below Kalkajaka at an elevation of . The river flows in highly meandering course generally north, then east, then south and then east, through the rainforest where the water is fresh. At this convergence point, an abundance of wildlife congregate, particularly fish. The river is joined by two minor tributaries before flowing through the Cairns Marine Park through thick mangrove swamps where the water is highly saline; and then empties into the Coral Sea, north of . The mouth of the Daintree River opens onto a giant sandbar that shifts with each changing tide. The river descends over its ...

Rheophyte
A rheophyte is a plant that lives in fast moving water currents in an environment where few other organisms can survive. Rheophytes tend to be found in currents that move at rates of one to two meters per second and that are up to 1 to 2 m deep. The amount of force produced by these currents, and the damaging debris they can carry, makes this environment inhospitable to most plants. Rheophytes are able to live in such environments because their leaves are streamlined so as put up little resistance to the flow of water. The leaves tend to be quite narrow and flexible as well. Simply being an aquatic plant Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that ... with narrow leaves is not a sufficient condition for being a rheophyte. In order to prevent being uprooted by the rushing currents, ...

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of ...
