Adamantinia
''Adamantinia'' is a monotypic genus of orchids (family Orchidaceae), described in 2004 by Cássio van den Berg and Cezar Neubert Gonçalves. The name is a reference to Chapada Diamantina, Brazil, where this species comes from. The single species, ''Adamantinia miltonioides'', is native to the Serra do Sincorá range (Brazil, Bahia, South America). It grows as an epiphyte at sunny positions, at about 900m altitude. Plants bear more or less clustered unifoliate pseudobulbs (rarely bifoliate), coriaceous dark-olive leaves, and possess long inflorescences with successive flowering. Flowers are showy, pink, with similar petals and sepals and a showy dark pink lip, with very small side lobes. Column is short, with a broad stigma. DNA data from trnL-F plastid sequences indicate relationships to ''Leptotes'' and ''Isabelia ''Isabelia'' is an orchid genus formed by three tiny species and one natural hybrid, spread from the Northeast of Brazil to Argentina, which are closely rela ...

Cássio Van Den Berg
Cássio van den Berg (born 1971) is a Brazilian botanist, noted for work in orchid classification and evolution, especially great changes in the generic circumscriptions of ornamental orchids in the genus ''Cattleya'', based on DNA studies for the subtribe Laeliinae. Career Based on DNA studies studies, he proposed a fusion of the genera ''Cattleya and Sophronitis'', and also included in this genus the Brazilian species of ''Laelia''. In Laeliinae, the studies pointed out to the separation of subtribe Ponerinae, and the transfer of ''Dilomilis'' and ''Neocogniauxia'' to Pleurothallidinae. He also worked in the taxonomy of other orchid genera, such as ''Acianthera'', ''Baptistonia'', ''Bulbophyllum'', ''Cymbidium'', ''Encyclia'', ''Galeandra'', ''Isabelia'' and '' Pleione''. In 2004, he described a new genus of Laeliinae, ''Adamantinia'' Van den Berg & C.N.Gonç. Currently he is full professor and curator of the Laboratory of Plant Molecular Systematics. at Universidade Estadual ... [...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 t ... [...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 wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Epidendroideae Genera
In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Isabelia
''Isabelia'' is an orchid genus formed by three tiny species and one natural hybrid, spread from the Northeast of Brazil to Argentina, which are closely related to the genus '' Constantia''. During more than a century ''Isabelia'' was a genus formed by just one species, however, around 1968, it was merged with genus ''Neolauchea'', also unispecific. In 2001, a third genus was added to it, ''Sophronitella''. The genus name is abbreviated ''Isa.'' in cultivation. Distribution ''Isabelia'' are epiphytic or rarely rupicolous species that are just occasionally found but usually grow into large colonies, spread in the Atlantic Forest of Brazil from north Bahia to Rio Grande do Sul, both in the humid slopes of Serra do Mar and in the drier forests of the Brazilian Plateau, from sea level to fifteen hundred meters of altitude. ''I. virginalis'' is also found in Paraguay and north of Argentina. ''Isabelia pulchella'' exists from Rio de Janeiro to Rio Grande do Sul, (1975). ''Or ...

Leptotes (plant)
''Leptotes'', abbreviated Lpt in horticultural trade, is a genus of orchids formed by nine small species that grow in the dry jungles of south and southeast Brazil, and also in Paraguay or Argentina. They are small epiphytic plants of caespitose growth that sometimes resemble little ''Brassavola'', as they share the same type of thin terete leaves, though they are more closely related to ''Loefgrenianthus''. Some species of ''Leptotes'' are widely cultivated and form showy displays when completely in bloom although they are not among the easiest to grow. The majority of the species are not cultivated and some are so rare to be almost unknown; five of the nine species have been described since 2000. Besides being cultivated for their ornamental value, there are records of the flowers and fruits of '' Leptotes bicolor'' being used as a substitute for vanilla in milk, ice cream, tea and candies. Distribution The species of ''Leptotes'' were originally discovered in the Atlantic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals (biotic pollination), or in rare cases from surrounding water ( hydrophily). Stigma can vary from long and sle ... [...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 a ...

Inflorescences
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is als ...
