Ambrella (plant)
''Ambrella'' is a monotypic genus in the orchid family.De La Bathie, H. P. (1934)"Ambrella, genre nouveau d'Orchidées (Angraecoïdées) de Madagascar."Bulletin de la Société Botanique de France, 81(4), 655-657. The single species, ''Ambrella longituba'' is endemic to Madagascar. The type specimen was collected and described by Joseph Marie Henry Alfred Perrier de la Bâthie in 1934. Description The plants are relatively small, epiphytic orchids. The flowers are big in relation to the size of the plants. The sepals are free and resemble the petals. The unusual, 45 mm long, spurred labellum is tubulate and encloses the column. The inner surface of the tube is covered with trichomes. Ecology This species is native to the semi-dry forests of the Northern tip of Madagascar at altitudes of 800 m above sea level. It has been found growing on branches of ''Viguieranthus alternans ''Viguieranthus'' is a genus of flowering plants in the legume family, Fabaceae. It be ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Orchids Of Madagascar
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angraecinae
Angraecinae is a subtribe in the family Orchidaceae. The subtribe consists of approximately 18 genera and about 360 species. The type genus is ''Angraecum''. Most of the genera are endemic to Africa, Madagascar and other Indian Ocean Islands, a few genera can also be found in the Americas. Taxonomy Recent scholarship has led to proposed reorganization of this subtribe. The proposed change would have '' Campylocentrum'' and all leafless Neotropical genera transferred to a new subtribe under tribe Vandeae to be called Campylocentrinae. That would leave only the Palaeotropical genera in the Angraecum alliance within this subtribe. There is, however, not sufficient scientific agreement to justify moving the "Campylocentrinae" at this time. Angraecum Alliance *''Aeranthes'' Lindl., 1824 (47 spp.) *''Ambrella'' H.

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

Montagne D'Ambre National Park
Montagne d'Ambre National Park is a national park in the Diana Region of northern Madagascar. The park is known for its endemic flora and fauna, water falls and crater lakes. It is north of the capital, Antananarivo and is one of the most biologically diverse places in all of Madagascar with seventy-five species of birds, twenty-five species of mammals, and fifty-nine species of reptiles known to inhabit the park. Geography The park covers an area of on an isolated volcanic massif, of mostly basaltic rock, above the surrounding dry region. Attractions include spectacular waterfalls and several crater lakes. There are numerous rivers and streams and the park is a water catchment area for the town of Antsiranana, which is surrounded by dry, sparse forests and semi-desert with succulent plants. Annual rainfall in the park is compared with around the town. The area is named after the deposits of copal, a soft form of amber. Amber is one of the most accessible parks in northern M ...

Phorophyte
In botany phorophytes are plants, on which epiphyte An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phoroph ...s grow. The term is composed of ''phoro'', meaning bearer or carrier and ''phyte'', meaning plant. Commensalistic interactions The epiphytes benefit from the habitats provided, but the phorophyte is unaffected. In other words, the obligate epiphytes utilize phorophytes as habitats, without parasitizing them.Sáyago, R., Lopezaraiza-Mikel, M., Quesada, M., Álvarez-Añorve, M. Y., Cascante-Marín, A., & Bastida, J. M. (2013). Evaluating factors that predict the structure of a commensalistic epiphyte–phorophyte network.

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...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 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 serie''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. published ''Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Column (botany)
The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. The top part of the column is formed by the anther, which is covered by an anther cap. This means that the ''style'' and ''stigma'' of the pistil, with the filaments and one or more anthers, are all united. Orchidaceae The stigma sits at the apex of the column in the front but is pointing downwards after resupination (the rotation by 180 degrees before unfolding of the flower). This stigma has the form of a small bowl, the clinandrium, a viscous surface embedding the (generally) single anther. On top of it all is the anther cap. Sometimes there is a small extension or little beak to the median stigma lobe, called rostellum. Column wings may project laterally from the stigma. The column foot is formed by the atta ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...
