Operculicarya Decaryi
''Operculicarya decaryi'', known as elephant tree or jabily, is a thick stemmed succulent plant species in the family (biology), family Anacardiaceae, named after the botany, botanical collector :fr:Raymond Decary, Raymond Decary. It is found in Madagascar and is also grown as a bonsai tree. It has small (less than 2 mm) red flowers in winter. The inflorescence is at the end of short branches and often consist of about five flowers. Woody cuttings need a soil mixture kept uniformly moist for propagation. It can also be propagated using pieces of the tuberous roots. It is drought tolerant and does well in full sun in most places. It cannot tolerate freezing conditions.

Comoro Islands
The Comoro Islands are a group of volcanic islands in the Mozambique Channel, an arm of the Indian Ocean lying between Madagascar and the African mainland. Three of the islands form the Union of the Comoros, a sovereign nation, while Mayotte belongs to France.

Dioecious Plants
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Anacardiaceae Genera
The Anacardiaceae, commonly known as the cashew family or sumac family, are a Family (biology), family of flowering plants, including about 83 genera with about 860 known species. Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an Irritation, irritant. The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus ''Anacardium''), mango, Toxicodendron vernicifluum, Chinese lacquer tree, Spondias mombin, yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, Cotinus, smoke tree, Sclerocarya birrea, marula and Amphipterygium adstringens, cuachalalate. The genus ''Pistacia'' (which includes the pistachio and Pistacia lentiscus, mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae. The cashew family is more abundant in warm or tropical regions with only a few species living in the temperate zones. Mostly native to tropical Americas, ...

Pachycaul
Pachycauls are plants with a disproportionately thick trunk, for their height, and relatively few branches. With certain pachycaul species, particularly the more succulent varieties, they are commonly referred to as "caudiciformes", a reference to their trunk development of a moisture-filled caudex for periods of drought. By comparison, trees with thin twigs, such as oaks (''Quercus''), maples ('' Acer'') and ''Eucalyptus'', are called leptocauls; those with moderately thick twigs, such as ''Plumeria'', are called mesocauls. Pachycauls can be the product of exceptional primary growth (as with Arecaceae and Cycadaceae) or disproportionate secondary growth, as with the baobabs (''Adansonia''). The word is derived from the Greek ''pachy-'' (meaning "thick" or "stout") and the Latin ''caulis'' (meaning "stem"). All of the arboreal (treelike) species of Cactaceae are pachycauls, as are most of the Arecaceae, Cycadaceae and ''Pandanus''. The most extreme pachycauls are the floodplains, ...

Aldabra
Aldabra, the world's second-largest coral atoll (the largest is Kiritimati), is located east of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands (Seychelles), Outer Islands of the Seychelles, with a distance of 1,120 km (700 mi) southwest of the capital, Victoria, Seychelles, Victoria on Mahé, Seychelles, Mahé Island. Initially named by Arab seafarers for its harsh environment, Aldabra became a French colonial empire, French colony dependency in the 18th century, leading to the exploitation of its natural resources, particularly giant tortoises. After passing through British hands, Aldabra faced potential military use in the 1960s, but international protests resulted in its protection. The atoll boasts unique geography, featuring the world's largest raised coral reef and a large shallow lagoon. Aldabra's history involves human impact, including failed agricultural ventures.

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Marie Henry Alfred Perrier De La Bâthie
Joseph Marie Henry Alfred Perrier de la Bâthie (11 August 1873 – 2 October 1958) was a French botany, botanist who specialized in the plants of Madagascar. He is the nephew of Eugène Pierre Perrier de la Bâthie, (1825-1916), another botanist, who also collected plants with him. He delineated the two chief floristic provinces of Madagascar (''see'' Ecoregions of Madagascar). Some of his works include ''La végétation malgache'' (1921), ''Biogéographie de plantes de Madagascar'' (1936), and numerous volumes of the series ''Flore de Madagascar et des Comores'' (1946-1952). Honours The orchid genus ''Neobathiea'' (originally ''Bathiea'') was named in his honor, as was the indriid lemur Perrier's sifaka (''Propithecus perrieri''). He has other plant genera named in his honour. Such as in 1905, botanist Lucien Désiré Joseph Courchet published ''Perriera'', a genus of flowering plants from Madagascar, belonging to the family Simaroubaceae. Then in 1915, botanist Hochr. publish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
