Syzygium Clavatum
''Syzygium claviflorum'' is a tree in the Myrtaceae family. It is native to the north of the Australian continent and in tropical and subtropical Asia. It is used for timber, as fuel, as human and cattle food, and for dye. Stunted specimens can be found on the top of the plateau of Bokor National Park, Cambodia. Description An evergreen tree that grows some 10-20m tall in Southeast Asia, 3-15m tall in Zhōngguó/China. Trees in the North Queensland Rainforests grow quickly to a large size, reaching some 180 to 270cm diameter. The bark is often rather pale, greyish-white to greyish-brown. The leaves have a depressed midrib and a grooved petiole on the upper surface, the blade is 6.5-13.2 by 2.9-5.8cm in size. Oil dots that are quite variable in size can be seen with a hand-lens. There are about 16-37 lateral veins on each side of the midrib. The inflorescence bracts are deciduous, and absent at full flower opening, anthesis. In the flowers the calyx tube, hypanthium, and pedice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthers
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western New Guinea
Western New Guinea, also known as Papua, Indonesian New Guinea, or Indonesian Papua, is the western half of the Melanesian island of New Guinea which is administered by Indonesia. Since the island is alternatively named as Papua, the region is also called West Papua ( id, Papua Barat). Lying to the west of Papua New Guinea and considered a part of the Australian continent, the territory is almost entirely in the Southern Hemisphere and includes the Schouten and Raja Ampat archipelagoes. The region is predominantly covered with ancient rainforest where numerous traditional tribes live such as the Dani of the Baliem Valley although a large proportion of the population live in or near coastal areas with the largest city being Jayapura. Within five years following its proclamation of independence in 1945, the Republic of Indonesia (for a time part of the United States of Indonesia) took over all the former territories of the Dutch East Indies except Western New Guinea, ac ...

Melville Island (Australia)
Melville Island ( Tiwi: ''Yermalner'') is an island in the eastern Timor Sea, off the coast of the Northern Territory, Australia. Along with Bathurst Island and nine smaller uninhabited islands, it forms part of the group known as the Tiwi Islands, which are under the jurisdiction of the Northern Territory in association with the Tiwi Land Council as the regional authority.

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 ().

Syzygium Apodophyllum
''Syzygium apodophyllum'' is a tree in the Myrtaceae family endemic to north Queensland. The fruit is edible. It is a host for the exotic plant-pathogen fungus ''Austropuccinia psidii'', which is causing a lot of damage to vegetation communities and economic plants.

Cataphyll
In plant morphology, a cataphyll (sometimes also called a ''cataphyllum'' or cataphyll leafJackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928) is a reduced, small leaf. Many plants have both "true leaves" (''euphylls''), which perform most of the photosynthesis, and cataphylls, which are modified to perform other functions. Cataphylls include bracts, bracteoles and bud scales, as well as any small leaves that resemble scales, known as scale leaves. The functions of cataphylls, such as bud scales, may be short-lived, and they are often shed after their function is fulfilled. Etymology Cataphyll comes from the Ancient Greek , meaning "down", and , meaning "leaf". Forms In some cases, cataphylls perform a transient function, after which they die and may shed. Those that shed early are said to be caducous. The sepals of '' Papaver'' species are shed during the very opening of the pet ...
