Cycas Condaoensis
''Cycas condaoensis'' is a species of cycad endemic to the Côn Đảo Islands off the coast of southern Vietnam Southern Vietnam ( vi, Nam Bộ) is one of the three geographical regions of Vietnam, the other two being Northern and Central Vietnam. It includes 2 administrative regions, which in turn are divided into 19 ''First Tier units'', of which 17 a ....

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] |
Côn Đảo
The Côn Đảo ("Côn Island") are an archipelago of Bà Rịa–Vũng Tàu province, in the Southeast region of Vietnam, and also a district () of this province. Geography Situated about from Vũng Tàu and from Ho Chi Minh City, the group includes 16 mountainous islands and islets. The total land area reaches and the local population is about 5,000. The islands are composed of magmatic rocks of different ages. Hòn Bảy Cạnh, Hòn Cau and Hòn Bông Lang are composed of cretaceous microgranite rocks. The northern part of Côn Đảo Island is composed of quartz diorite and granite - granodiorite of late mesozoic- early cenozoic age, and is partially covered by quaternary marine sediments. The southern part of this island and Hòn Bà island are composed of the rhyolite and intrusive formations of unknown age. On the western slope of Côn Đảo Island, there exist groups of outcrops of diorite and microgranite penetrated by big quartz band The island group is served b ...

Southern Vietnam
Southern Vietnam ( vi, Nam Bộ) is one of the three geographical regions of Vietnam, the other two being Northern and Central Vietnam. It includes 2 administrative regions, which in turn are divided into 19 ''First Tier units'', of which 17 are provinces and 2 are municipalities. In a sub-context, "Southern Vietnam" may include part of Central Vietnam. Known as ''Nam Bộ'' today in Vietnamese, it was historically called as '' Gia Định'' (1779–1832), ''Nam Kỳ'' (1832–1945), ''Nam Bộ'' (1945–48), and ''Nam Phần'' (1948–75). Southern Vietnam (''Basse-Cochinchine'' in French, or Lower Cochinchina), whose principal city is Saigon, is the newest territory of the Vietnamese people in the movement of '' Nam tiến'' (Southward expansion). This region was also the first part of Vietnam to be colonized by the French as French Cochinchina. Southern Vietnam region was incorporated into the Kingdom of Funan from 1st century CE until 6th century CE. Administration Muni ...

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 ...
