Dypsis Decaryi
''Dypsis decaryi'' is a species of flowering plant in the Arecaceae family. It is commonly known as the triangle palm. It is indigenous to the Madagascan rainforest. Some specimens grow to a height of some in the wild. It is relatively new to cultivation however, so outside its native habitat it rarely achieves anything like that height. The leaves are about in length, growing almost upright from the trunk and arching gracefully outward about a metre from their tips. The leaf bases are arranged in three vertical columns set about 120 degrees apart on the main stem, forming a triangular shape in cross section. This shape has given rise to the palm's common name. The inflorescences branch out from the axils of the lower leaves. They produce yellow and green flowers that later produce round black fruit about in diameter. The palm is a fine ornamental plant and is most valuable as a specimen tree or accent plant when grown out in the open to display show its remarkable shape to ...

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).

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] |
Arecaceae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Madagascar Lowland Forests
The Madagascar lowland forests or Madagascar humid forests are a tropical and subtropical moist broadleaf forests, tropical moist broadleaf forest ecoregion found on the eastern coast of the island of Madagascar, home to a plant and animal mix that is 80 to 90% endemic, with the forests of the eastern plain being a particularly important location of this endemism. They are included in the Global 200 list of outstanding ecoregions. Geography The ecoregion constitutes a narrow strip of lowland forests between Madagascar's east coast and the mountainous central highlands, from sea level to elevation. It covers an area of approximately . The ecoregion is under the direct influence of the oceanic trade winds, which maintain a warm, humid climate; rainfall is above 2,000 mm per year and can reach up to 6,000 mm on the Masoala peninsula. The lowland forests extend from Marojejy in the north to the southeast corner of the island. At the northern edge of ecoregion around Vohemar, the moi ...

Habit (biology)
Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: *In zoology (particularly in ethology), habit usually refers to aspects of more or less predictable ''behaviour'', instinctive or otherwise, though it also has broader application. Habitus refers to the characteristic form or morphology of a species. *In botany, habit is the characteristic form in which a given species of plant grows (see plant habit).Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Behavior In zoology, ''habit'' (not to be confused with ''habitus'' as described below) usually refers to a specific behavior pattern, either adopted, learned, pathological, innate, or directly related to physiology. For example: * ...the atwas in the ''habit'' of springing upon the oor knockerin order to gain admission... * If these sensitive parrots are kep ...

Andohahela National Park
Andohahela National Park, in south-east Madagascar, is remarkable for the extremes of habitats that are represented within it. The park covers of the Anosy mountain range, the southernmost spur of the Malagasy Highlands and contains the last humid rainforests in the southern part of Madagascar. The Park was inscribed in the World Heritage Site in 2007 as part of the Rainforests of the Atsinanana. History Andohahela has been a protected area since 1939 but did not become a national park until 1998. Geography Andohahela National Park is north-west of Tôlanaro and at the southern end of the Malagasy Highlands. The park is divided into three zones. The first, Malio, ranges from to the summit of Pic d' Andohahela at , and has dense lowland and montane rainforest with more than two hundred species of tree ferns, orchids, wild vanilla, lemurs and many birds.

Dypsis
''Dypsis'' is a genus of flowering plants in the family Arecaceae. They are slender, evergreen palms with yellow flowers carried in panicles amongst the pinnate leaves. Many ''Dypsis'' species have aerial branching (above the main trunk), a rare growth habit among palms. Some have marcescent leaves that remain attached after death and trap litter for nutrients. Etymology The etymology is obscure but may be related to the Greek ' ‘I dive’ or ' ‘diver’. The species are native to Tanzania, Madagascar, and various islands in the Indian Ocean (Mauritius and Comoros). A few are naturalized in other regions, especially in the Caribbean The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Se ....

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] |
