Epidendrum Geniculatum
''Epidendrum geniculatum'' is a deciduous, sympodial, caespitose orchid native to the Brazilian states of Espírito Santo and Rio de Janeiro, at elevations from 300 – 800 m. Synonymy and confusion A description of ''Epidendrum geniculatum'' was published in 1882 by João Barbosa Rodrigues. Eight years later, in 1890, Joseph Dalton Hooker published a description of an orchid, under the name of ''Epidendrum geniculatum'' for which William Roxburgh had published a description 70 years earlier, with the name ''Aerides multiflora''. Thus, ''Epidendrum geniculatum'' Hook.f. is a synonym for ''Aerides multiflora'' Roxb., and a very different taxon from ''Epidendrum geniculatum'' Barb.Rodr., the subject of this article. Description The stems of ''E. geniculatum'' are flattened and covered by the bases of the rather thin leaves, which drop before the seed capsule matures. The flowers, born in Winter and early Spring (July–September) on a short peduncle erupting from a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
João Barbosa Rodrigues
João Barbosa Rodrigues (June 22, 1842 – March 6, 1909) was considered one of Brazil's greatest botanists, known especially for his work on orchids and palms. For nearly two decades he was director of the Botanic Garden of Rio de Janeiro. Something of a polymath, he was a prolific botanical artist who also made contributions to his country's ethnography, geography, linguistics, zoology, and literature. Early life and education Rodrigues was born on June 22, 1842, in São Gonçalo do Sapucaí, Brazil, and was initially raised in Campanha, in the state of Minas Gerais, before the family returned to Rio in 1858. His father was a Portuguese merchant, and his mother was a Brazilian of Indian descent. He had several siblings: brothers João Baptista and Arthur and sisters Maria and Olympia. He showed early ability as a writer and he was always interested in natural science, particularly in collecting insects and plants. However, he went to the Central School of Engineering in Rio de ...

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Orchids Of Brazil
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] |
Epidendrum Subg
''Epidendrum'' , abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family. With more than 1,500 species, some authors describe it as a mega-genus. The genus name (from Greek ''επί, epi'' and ''δένδρον, dendron'', "upon trees") refers to its epiphytic growth habit. When Carl Linnaeus named this genus in 1763, he included in this genus all the epiphytic orchids known to him. Although few of these orchids are still included in the genus ''Epidendrum'', some species of ''Epidendrum'' are nevertheless not epiphytic. Distribution and ecology They are native to the tropics and subtropical regions of the American continents, from North Carolina to Argentina. Their habitat can be epiphytic, terrestrial (such as '' E. fulgens''), or even lithophytic (growing on bare rock, such as '' E. calanthum'' and '' E. saxatile''). Many are grown in the Andes, at altitudes between 1,000 and 3,000 m. Their habitats include humid jungles, d ... [...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 ...

Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympodial
Sympodial growth is a bifurcating branching pattern where one branch develops more strongly than the other, resulting in the stronger branches forming the primary shoot and the weaker branches appearing laterally. A sympodium, also referred to as a sympode or pseudaxis, is the primary shoot, comprising the stronger branches, formed during sympodial growth. The pattern is similar to dichotomous branching; it is characterized by branching along stems or hyphae. In botany, sympodial growth occurs when the apical meristem is terminated and growth is continued by one or more lateral meristems, which repeat the process. The apical meristem may be consumed to make an inflorescence or other determinate structure, or it may be aborted. Types If the sympodium is always formed on the same side of the branch bifurcation, e.g. always on the right side, the branching structure is called a helicoid cyme or bostryx. If the sympodium occurs alternately, e.g. on the right and then the left, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerides Multiflora
''Aerides multiflora'', the multi-flowered aerides, is a species of orchid, native to Southeast Asia, the Coromandel Coast, and Bangladesh.
