''Cycas schumanniana'' is a species of cycad endemic to New Guinea. Range It is found in northern New Guinea along the foothills of the Bismarck Range, where it is found in the valleys of the Markham River, Ramu River, and Bulolo River watersheds as far as Wau, Papua New Guinea Wau is a town in Papua New Guinea, in the province of Morobe. It has a population of approx 5,000 and is situated at an altitude of around 1100 metres.

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk (botany), trunk with a crown (botany), 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 Arecaceae, palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their fertilization, 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 (strobilus, strobili), somewhat similar to conife ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bismarck Range
The Bismarck Range is a mountain range in the Western Highlands Province of Papua New Guinea. The range is named after the German Chancellor, Otto von Bismarck. From the 1880s to 1914, this part of the island was a German colony. The highest point is Mount Wilhelm at 4,509 m (14,793 ft). At over 3,400 metres (11,155 ft), the landscape is alpine with tundra, in spite of the tropical climate. The Ramu The Ramu River is a major river in northern Papua New Guinea.

Ramu River
The Ramu River is a major river in northern Papua New Guinea. The headwaters of the river are formed in the Kratke Range from where it then travels about northwest to the Bismarck Sea. Along the Ramu's course, it receives numerous tributaries from the Bismarck Range to the south and the Finisterre and Adelbert. History For many millennia, people have lived along the river, and the river has formed the basis for food, transport, and culture. German exploration The area encompassed by the Ramu was part of Kaiser-Wilhelmsland when Germany established German New Guinea in 1884. The Germans were quick to explore their territory, and the mouth of the Ramu was discovered in 1886 by Vice-Admiral Freiherr von Schleinitz after returning to Finschhafen from an expedition to the nearby Sepik.Souter (1963) p. 73 Schleinitz called the Ramu, ''Ottilien'' after his ship the ''Ottilie''.

Wau, Papua New Guinea
Wau is a town in Papua New Guinea, in the province of Morobe. It has a population of approx 5,000 and is situated at an altitude of around 1100 metres. Wau was the site of a gold rush during the 1920s and 30s when prospective gold diggers arrived at the coast at Salamaua and struggled inland along the Black Cat Track. At the Battle of Wau in January 1943, the Australian Army stopped an advance by the Japanese. A road was established soon after World War II to Lae and this fostered the further development of local timber and agricultural industries that were originally established in support of the mining industry. While much of the mineral reserves have been extracted, industrial gold mining continues at Edie Creek and at the newly established Hidden Valley Gold Mine operated by Morobe Goldfields (a subsidiary of Harmony Gold - South Africa).

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 ar ...
