Oncidiinae
The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related. This subtribe consists of about 70 genera with over 1000 species, with '' Oncidium'' as its largest genus. These genera consist of a single floral type based on the angle of the attachment of the lip to the column, reflecting pollinator preferences. This has however led to several unreliable results and polyphyletic taxa within '' Oncidium''. These were transferred to ''Gomesa'' and a new genus '' Nohawilliamsia'', has been described for ''Oncidium orthostates'' Most Oncidioid species have well-developed pseudobulbs and conduplicate leaves. It is possible to form hybrids in some instances between multiple genera within the Oncidiinae. These hybrids are often colloquially referred to as "intergenerics." Genera Genera recognized in Chase et al.'s 2015 classification of Orchidaceae: * ''Aspasia'' * ''Brassia'' * '' Caluera'' * ''Capanemia'' * ''Caucaea'' * '' Centro ...

Heinrich Gustav Reichenbach
Heinrich Gustav Reichenbach (Dresden, 3 January 1823 – Hamburg, 6 May 1889) was a botanist and the foremost German orchidologist of the 19th century. His father Heinrich Gottlieb Ludwig Reichenbach (author of ''Icones Florae Germanicae et Helveticae'') was also a well-known botanist. Biography He started his study of orchids at the age of 18 and assisted his father in the writing of ''Icones''. He became a Doctor in Botany with his work on the pollen of orchids (see ‘Selected Works’). Soon after his graduation, Reichenbach was appointed to the post of extraordinary professor of botany at the Leipzig in 1855. He then became director of the botanical gardens at the Hamburg University (1863-1889). At that time, thousands of newly discovered orchids were being sent back to Europe. He was responsible for identifying, describing, classifying. Reichenbach named and recorded many of these new discoveries. He probably was not the easiest of personalities, and used to boast about h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain Forest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...

Inflorescence
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 al ...

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] |
