Strychnos Psilosperma
''Strychnos psilosperma'', known as the strychnine tree or threaded boxwood, is a shrub or small tree endemic to New South Wales and Queensland in Australia. It may reach a height of 18 metres. It occurs as far south as the Clarence River, New South Wales to Cape York at the northernmost tip of Australia. The bark is grey, with glossy pointed leaves creating a thick canopy. Small white, scented flowers occur in the warmer months. Fruit are orange to red berries, ripening to black. All parts of this plant are toxic. It may be grown in full sun with good drainage. The habitat is semi-evergreen deciduous vine forest, or mixed eucalyptus forest. A common associate tree is the Hoop Pine ''Araucaria cunninghamii'' is a species of ''Araucaria'' known as hoop pine.

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Cape York Peninsula
The Cape York Peninsula is a peninsula located in Far North Queensland, Australia. It is the largest 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.

Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat (ecology), habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred millimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy (forest), canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoop Pine
''Araucaria cunninghamii'' is a species of ''Araucaria'' known as hoop pine. Other less commonly used names include colonial pine, Queensland pine, Dorrigo pine, Moreton Bay pine and Richmond River pine. The scientific name honours the botanist and explorer Allan Cunningham, who collected the first specimens in the 1820s. Description The leaves on young trees are awl-shaped, 1–2 cm long, about 2 mm thick at the base, and scale-like, incurved, 1–2 cm long and 4 mm broad on mature trees. The cones are ovoid, 8–10 cm long and 6–8 cm diameter, and take about 18 months to mature. They disintegrate at maturity to release the nut-like edible seeds. Subspecies There are two varieties: *''Araucaria cunninghamii'' var. ''cunninghamii'' – Australia, from northeast New South Wales to east-central Queensland, at 0–1,000 m elevation. *''Araucaria cunninghamii'' var.

Strychnos
''Strychnos'' is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 200 accepted species of trees and lianas. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare. Etymology The name ''strychnos'' was applied by Pliny the Elder in his ''Natural History'' to ''Solanum nigrum''. The word is derived from the Ancient Greek στρύχνον (''strúkhnon'') – "acrid", "bitter". The meaning of the word ''strychnos'' was not fixed in Ancient Greece, where it could designate a variety of different plants having in common the property of toxicity. Distribution The genus has a pantropical distribution. Taxonomy The genus is divided into 12 sections, though it is conceded that the sections do not reflect evolution of th ...

Flora Of Queensland
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...
