Voanioala
''Voanioala gerardii'', commonly known as the forest coconut, is a species of flowering plant in the family Arecaceae. It is a relative of the coconut, and is generally regarded as monotypic within the genus ''Voanioala''. However, a team of geneticists headed by Bee F. Gunn found sufficient genetic variation within ''Voanioala'' to constitute at least two and possibly four cryptospecies. ''Voanioala'' is endemic to Madagascar, and is threatened by habitat loss. ''Voanioala'' is harvested for its edible seeds and palm heart. It is estimated that there are fewer than fifteen mature trees remaining. Description The forest coconut is a Madagascan tree that can reach 15–20 meters high in the wild. It is supported by a strong root base, and its leaves sprout from the crown. Voanioala can reach up to 5 meters in height. The leaflets are waxy, green, and stiff, and seventy of them can grow from each side of a leaf. The fruit grows in groups at the crown with a thick reddish-brown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocoseae
Cocoseae is a tribe of cocosoid palms of the family Arecaceae. Description The fruit of the Cocoseae is a modified drupe, with a sclerenchymatous epicarp and a highly developed mesocarp, formed mainly by parenchyma . The endocarp is generally sclerenchymatous and protects the seeds from predation and drying. The most obvious synapomorphy In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have ... of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination. Distribution The Cocoseae are distributed mainly in the Neotropical regions, with two genera endemic to Africa (''Jubaeopsis'' and ''Elaeis'') and Madagascar ( ''Beccariophoenix'' and ''Voanioala'' ), respectively. Systematics The Cocoseae in the sense of Dransfield et al. (2008) are ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coconut
The coconut tree (''Cocos nucifera'') is a member of the palm tree family ( Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The name comes from the old Portuguese word '' coco'', meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, form a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called ''coconut water'' or ''coconut juice''. Mature, ripe coconut ...

John Dransfield
John Dransfield (born 1945) is an honorary research fellow and former head of palm research at the Royal Botanic Gardens, Kew, United Kingdom, as well as being an authority on the phylogenetic classification of palms. Dransfield has written or contributed to several books on palms, notably both the first and second editions of ''Genera Palmarum''. The first edition was the standard reference for palm evolution and classification and the second edition, expanding on the original, is expected to achieve that same benchmark. He studied at the University of Cambridge, B.A.(1967), M.A. (1970) and Ph.D. (1970) before working at Kew Gardens. In 2004, Dransfield was awarded the Linnean Medal, an annual award given by the Linnean Society of London. The genus '' Dransfieldia'' was named for him, as was the species '' Adonidia dransfieldii''. He married Dr Soejatmi Dransfield (née Soejatmi Soenarko) in Malaysia (1977).

Bay Of Antongil
''Helodranon' Antongila'' (Bay of Antongila), more commonly called Antongil Bay in English, is the largest bay in Madagascar. This bay is on the island's east coast, toward the northern end of the eastern coastline of the island. It is within Analanjirofo administrative region. The bay is about long and wide. Forming the eastern edge of the bay is the Masoala peninsula. The island Nosy Mangabe and the town of Maroantsetra are situated at the northern end of the bay, while the southern end of the bay is near the site of the town of Mananara Avaratra and the mouth of the Mananara River (Analanjirofo) The Mananara River is one of the main rivers in north-eastern Madagascar. Its mouth is located in the Bay of Antongil, (Indian Ocean) near the city of Mananara Nord in the Analanjirofo Analanjirofo is a region in northeastern Madagascar. Until ....

Endemic Flora Of Madagascar
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] |
Monotypic Arecaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Rainforests
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...

Masoala Peninsula
Masoala National Park, in northeast Madagascar, is the largest of the island's protected areas. Most of the park is situated in Sava Region and a part in Analanjirofo. Created in 1997, the park protects 2,300 square kilometres of rainforest and 100 square kilometres of marine parks. The Masoala Peninsula is exceptionally diverse due to its large size, and variety of habitats. Altogether, the park protects tropical rainforest, coastal forest, flooded forest, marsh, and mangrove. Three marine parks protect coral reefs and a dazzling array of marine life. Climate This is an exceptionally wet area of Madagascar. The driest part of the year is from September to December. As the park is accessible only by a three-hour boat journey, the cyclone season (January to March) is best avoided. Flora and fauna There are ten lemur species, including the red ruffed lemur, which is native to the peninsula. The island reserve of Nosy Mangabe is one of the best sites in Madagascar to try to glim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocotyledon
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaflet (botany)
A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a leaf, petiole or a branch of the leaf. Compound leaves are common in many plant families and they differ widely in morphology (biology), morphology. The two main classes of compound leaf morphology are Leaf shape, palmate and pinnate. For example, a ''Cannabis, hemp'' plant has palmate compound leaves, whereas some species of ''Acacia sensu lato, Acacia'' have pinnate leaves. The ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf is called a pinnule or pinnula.
