Aganisia
''Aganisia'' is a small South American genus in the orchid family (Orchidaceae), subfamily Epidendroideae. The genus was named after the Greek word ‘agnos’ (gratitude), perhaps referring to the sweet scent of its flowers. These dwarf, epiphytic climbing orchids occur in mountainous or savanna forests and alongside rivers in Trinidad, Brazil, Colombia, Venezuela, Guyana, French Guiana, Suriname and Peru. Aganisia produce pseudobulbs and small flowers produced from a creeping rhizome. These flowers generally reach 4 cm in width. Their color varies from a rose-tinted violet to a blue-tinted violet. The flower has a short column foot and an elongate stipe.Forzza, R. C. 2010. Lista de espécies Flora do Brasil . Jardim Botânico do Rio de Janeiro, Rio de Janeiro They are rarely cultivated.

Aganisia Cyanea
''Aganisia cyanea'' (formerly ''Acacallis cyanea'') is a showy species of orchid native to Colombia, Venezuela, Peru and Brazil and widely cultivated elsewhere as an ornamental. It is remarkable because some cultivars of this species produce blue flowers, the color blue being quite rare among the orchids. They are considered difficult to maintain in cultivation without a controlled growing environment.''Illustrated Encyclopedia of Orchids'' Biology ''Aganisia cyanea'' is found in very wet, lowland rain forests in northern South America growing on lower sections of the trunks of large trees. The plants can be submerged under water during monsoons for several weeks due to flooding in habitat with no apparent harm.''The Orchids, Natural History and Classification'', Robert L. Dressler. The plants grow from a creeping rhizome with inter-spaced pseudobulbs The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickenin ...

Orchidaceae
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] |
Zygopetalinae Genera
Zygopetalinae is an orchid subtribe in the tribe Cymbidieae with 418 species. Description Orchids in Zygopetalinae are mostly epiphytic but can be terrestrial, with pseudobulbs of one or several internodes or slender stems. All genera but one are sympodial. Leaves are convolute or duplicate, plicate, and articulate, with a smooth cuticle. Inflorescences of one to several spiral flowers rise from young shoots laterally. Flowers vary in size and can be resupinate. Columns can be winged or flattened and usually have a distinct foot. The anther can be either terminal or ventral, with an operculum. Velamen resembles that of the genus ''Cymbidium''. Plants have 46, 48, or 52 chromosomes. Genera Genera include: Distribution and habitat Species of the subtribe occur throughout the American tropics, from southern Mexico in North America to northern Argentina and Bolivia in South America. The northernmost species are of the genera '' Kefersteinia'' and '' Stenotyla'' in North Ameri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphytic Orchids
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 phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rondônia
Rondônia () is one of the 26 states of Brazil, located in the northern subdivision of the country (central-western part). To the west is a short border with the state of Acre, to the north is the state of Amazonas, in the east is Mato Grosso, and in the south and southwest is Bolivia. Rondônia has a population of 1,815,000 as of 2021. It is the fifth least populated state. Its capital and largest city is Porto Velho. The state was named after Cândido Rondon, who explored the north of the country during the 1910s. The state, which is home to 0.8% of the Brazilian population, is responsible for 0.6% of the Brazilian GDP. Geography Rondonia was originally home to over 200,000 km2 of rainforest, but has become one of the most deforested places in the Amazon. By 2003 around 70,000 km2 of rainforest had been cleared. The area around the Guaporé River is part of the Beni savanna ecoregion. The Samuel Dam is located in the state, on the Jamari River. History Dem ...

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 ...
