Borasseae
Borasseae is a tribe in the palm subfamily Coryphoideae. The tribe ranges from southern Africa and Madagascar north through the Arabian Peninsula to India, Indochina, Indonesia and New Guinea. Several genera are restricted to islands in the Indian Ocean. The two largest genera, ''Hyphaene'' and ''Borassus'', are also the most widespread. Description Borassoid palms typically have large, column-like trunks, though several species of ''Hyphaene'' have branching or clustered stems. The leaves are large, palmate and often with spines or sharp edges along the petioles. Leaves are retained on young palm stems, later falling to reveal prominent scars. All genera in the Borasseae are dioecious, with separate male and female trees; they are pleonanthic, flowering regularly for many years. Inflorescences are large and pendulous; the male flowers are much smaller than the female and are borne in clusters within catkin-like structures. Fruits contain hard, woody endocarps surrounding the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coryphoideae
The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting ''Mauritia'', ''Mauritiella'' and ''Lepidocaryum,'' all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds (excepting ''Guihaia''), while Calamoid palms have reduplicate (inverted V-shaped) leaf folds. Pinnate leaves do occur in Coryphoideae, in ''Phoenix'', '' Arenga'', ''Wallichia'' and bipinnate in ''Caryota''. Classification Subfamily Coryphoideae is divided into 8 tribes: * Sabaleae ** ''Sabal'' * Cryosophileae ** ''Schippia'' ** '' Trithrinax'' ** ''Zombia'' ** ''Coccothrinax'' ** ''Hemithrinax'' ** ''Thrinax'' ** ''Chelyocarpus'' ** ''Cryosophila'' ** ''Itaya'' ** ''Sabinaria'' * Phoeniceae ** ''Phoenix'' * Trachycarpeae ** ''Chamaerops'' ** ''Guihaia'' ** ''Trachycarpus'' ** ''Rhapidophyllum'' ** ''Maxburretia'' ** ''Rhapis'' ** ''Livistona'' ...

Lodoicea
''Lodoicea'', commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, ''Lodoicea maldivica'', is endemic to the islands of Praslin and Curieuse in the Seychelles. It has the biggest seed in a plant. It formerly also was found on the small islets of St Pierre, Chauve-Souris, and Ile Ronde (Round Island), all located near Praslin, but had become extinct there for a time until recently reintroduced. Taxonomy The name of the genus ''Lodoicea'' is given by Philibert Commerson, it may be derived from ''Lodoicus'', a Latinised form of ''Louis'' (typically '' Ludovicus''), in honour of King Louis XV of France. Other sources say that ''Lodoicea'' is from Laodice, the daughter of Priam and Hecuba. ''Lodoicea'' belongs to the Coryphoideae subfamily and tribe Borasseae. Borasseae is represented by four genera in Madagascar and one in Seychelles out of the seven worldwide. They are distributed on the coastlands surroun ...

Satranala
''Satranala decussilvae'' is a species of flowering plant in the Arecaceae family. It is a palm endemic to Madagascar. It is the only species in the genus ''Satranala'', and is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... There are perhaps 200 mature individuals remaining.

Borassus Aethiopum
''Borassus aethiopum'' is a species of '' Borassus'' palm from Africa. In English it is variously referred to as African fan palm, African palmyra palm, deleb palm, ron palm, toddy palm, black rhun palm, rônier palm (from the French). It is widespread across much of tropical Africa from Senegal to Ethiopia and south to northern South Africa, though it is largely absent from the forested areas of Central Africa and desert regions such as the Sahara and Namib. This palm also grows in northwest Madagascar and the Comoros. Description The typical form of ''Borassus aethiopum'' is a solitary palm to in height and in diameter at the base. In the river bottoms (floodplains) of many East African rivers (the Rufiji in Tanzania and the Tana in Kenya among others) a closely related form can be up to seven feet (2.1 meters) thick at breast height (4 feet (1.2 meters) above ground) and having the same thickness in its upper ventricosity. It also has a height of up to 100 feet ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medemia
''Medemia argun'' is a rare species of the palm tree family (Arecaceae) native to Egypt and Sudan. It is the only species in the genus ''Medemia''. The palm's dried dates have been found in ancient Egyptian tombs. Description ''Medemia argun'' is a robust, solitary-stemmed, dioecious palm up to tall with fan leaves forming a dense rounded crown. It grows in extreme desert conditions. It is typically found in dry river beds in which ground water is likely to occur. Distribution ''Medemia argun'' is found only in oases inside of the Nubian Desert, in southern Egypt and northern Sudan. The global population is divided in several sub-populations, with the most important (>90%) part of the population occurring in northern Sudan. The global population of ''Medemia argun'' was estimated at about 7,400 individuals in the middle of the 2000s. In Egypt, only 32 individuals were counted at Dungul Oases in 2007 (Ibrahim and Baker 2009). Its area of occupancy is restricted to 880 km². Con ...

Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and the ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
