It is found in Western Province, including the floodplains of the Fly River and near Daru to the west, and also extending to the Bensbach River The Bensbach River is a river in southwestern Papua New Guinea.

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones ( strobili), somewhat similar to conifer cones. Cycads have been reported to fix nitrogen in asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia).

Western Province (Papua New Guinea)
Western Province is a coastal province in southwestern Papua New Guinea, bordering the Indonesian province of Papua. The provincial capital is Daru. The largest town in the province is Tabubil. Other major settlements are Kiunga, Ningerum, Olsobip and Balimo. The provincial government has, as with the governments of North Solomons, Chimbu and Northern provinces, sought to change the name of the province. The government uses the name Fly River Provincial Government; however, this remains unofficial as it has not been changed in the Constitution of Papua New Guinea. Geography and ecology Western Province covers 99,300 km² and is the largest province in Papua New Guinea by area. There are several large rivers that run through the province, including the Fly River and its tributaries the Strickland and Ok Tedi rivers. The largest lake in Papua New Guinea, Lake Murray, is also in Western Province. This province is the only part of Papua New Guinea to hold land west ...

Fly River
The Fly River is the third longest river in the island of New Guinea, after the Sepik River and Mamberamo River, with a total length of and the largest by volume of discharge in Oceania, the largest in the world without a single dam in its catchment, and overall the 20th-largest primary river in the world by discharge volume. It is located in the southwest of Papua New Guinea and Papua Province of Indonesia. It rises in the Victor Emanuel Range arm of the Star Mountains, and crosses the south-western lowlands before flowing into the Gulf of Papua in a large delta. The Fly-Strickland River system has a total length of making it the longest river system of an island in the world, including Strickland River is the longest and largest tributary of Fly River, making it the farthest distance source of the Fly River.

Bensbach River
The Bensbach River is a river in southwestern Papua New Guinea. It is located just to the east of the Maro River in Merauke Regency, Indonesia, and just to the west of the Morehead River in Papua New Guinea. The mouth of the river, Torasi Estuary, marks part of the extreme southern boundary between Papua New Guinea and Indonesia. The river is strongly meandering and rather narrow. From the rivermouth, it stretches in a roughly northeasterly direction, and so is entirely located in PNG territory. It flows through the Trans-Fly savanna and grasslands, including the Tonda Wildlife Management Area. Europeans first discovered the river on 27 February 1893, and it was named after Jacob Bensbach, Dutch Resident at Ternate, by Sir William MacGregor. The local people call it the Torassi (sometimes spelled Torasi). Tonda languages are spoken in the Bensbach River area.

Cycas
''Cycas'' is a genus of plants belonging to a very ancient lineage, the Cycadophyta, which are not closely related to palms, ferns, trees or any other modern group of plants. They are evergreen perennials which achieved their maximum diversity in the Jurassic and Cretaceous periods, when they were distributed almost worldwide. At the end of the Cretaceous, when the non-avian dinosaurs became extinct, so did most of the cycas in the Northern Hemisphere. ''Cycas'' is the type genus and the only extant genus recognised in the family Cycadaceae. About 113 species are accepted. ''Cycas circinalis'', a species endemic to India, was the first cycad species to be described in western literature, and was the type of the generic name, ''Cycas''. The best-known ''Cycas'' species is '' Cycas revoluta''. Range The genus is native to the Old World, with the species concentrated around the equatorial regions - eastern and southeastern Asia including the Philippines with 10 species (9 of which a ...
