Phreatia Listeri
''Phreatia listeri'', commonly known as the Christmas Island caterpillar orchid, is a plant in the orchid family and is an epiphyte with four to six flat, blunt leaves in a fan-like arrangement. A large number of tiny, greenish white flowers are arranged along a thin flowering stem. It is endemic to Christmas Island. Description ''Phreatia listeri'' is a clump-forming epiphytic herb with a short stem, thin roots and between four and six flat, blunt, dark green leaves long and about wide in a fan-like arrangement. A large number of greenish white non-resupinate flowers long and wide are arranged along a thin flowering stem long. The sepals and petals are about long and do not spread widely. The labellum is about long and wide. Flowering occurs between September and October. Taxonomy and naming ''Phreatia listeri'' was first formally described in 1890 by Robert Allen Rolfe who published the description in the ''Journal of the Linnean Society, Botany''.

Robert Allen Rolfe
Robert Allen Rolfe (1855, Wilford, Nottinghamshire – 1921, Richmond, Surrey) was an English botanist specialising in the study of orchids. For a time he worked in the gardens at Welbeck Abbey. He entered Kew in 1879 and became second assistant. He was the first curator of the orchid herbarium at the Royal Botanic Gardens, Kew, founded the magazine ''The Orchid Review'', and published many papers on hybrids of different species of orchids. The genus ''Allenrolfea'' of amaranths was named after him by Carl Ernst Otto Kuntze. Rolfe was buried in Richmond Cemetery Richmond Cemetery is a cemetery on Lower Grove Road in Richmond in the London Borough of Richmond upon Thames, England. The cemetery opened in 1786 on a plot of land granted by an Act of Parliament the previous year. The cemetery has been expande .... Works Rolfe, Robert Allen (1883).

Plants Described In 1890
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Endemic Flora Of Christmas Island
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phreatia
''Phreatia'', commonly known as lace orchids, is a genus of flowering plants from the orchid family, Orchidaceae, native to regions bordering the Pacific and Indian Oceans. Plants in this genus are epiphytes, sometimes with pseudobulbs, in which case there are usually one or two leaves. Others lack pseudobulbs but have up to twelve leaves. A large number of small white or greenish flowers are borne on a flowering stem emerging from a leaf axil or from the base of the pseudobulb when present but the flowers do not open widely. There are about 220 species, distributed from tropical and subtropical Asia to the Pacific. Description Orchids in the genus ''Phratia'' are epiphytic herbs similar to those in the genus '' Thelasis'' and sometimes have pseudobulbs with one or two leaves or otherwise lack pseudobulbs and have up to twelve leaves. A large number of small flowers are arranged on a flowering stem that emerges from the top of the pseudobulb when present or from a leaf axil. The f ...

Rainforest
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 lea ...

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 ...

John Maclear
John Fiot Lee Pearse Maclear (27 June 1838 in Cape Town – 17 July 1907 in Niagara) was an admiral in the Royal Navy, known for his leadership in hydrography. He is best known for being commander of during the ''Challenger'' Expedition (1872–1876) under its commission captain, Sir George Nares, for the voyage of scientific discovery in which the ship went round the world. This expedition led to the science of oceanography, after which various ocean features are named, including the Challenger Plateau near New Zealand. During this expedition the Maclear's Rat on Christmas Island in the Indian Ocean was named after him. He is also honoured in the specific epithet of '' Dicliptera maclearii'', a plant in the family Acanthaceae which is endemic to Christmas Island. Royal Navy career Maclear entered the Navy in September 1851 as a cadet on board the frigate , then bearing the broad pennant of Commodore Christopher Wyvill, then commanding the Cape station. In her he saw servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Jackson Lister (naturalist)
Joseph Jackson Lister FRS (August 3, 1857 – February 5, 1927) was a British zoologist and plant collector from Leytonstone who collected biological specimens during travels in Africa, Asia, Australasia and the Pacific region. Life Lister's grandfather was also called Joseph Jackson Lister, and was a pioneer of high quality optical microscopes. Lister's uncle was Joseph Lister, 1st Baron Lister, the pioneer of antiseptic surgery. Lister attended St John's College, Cambridge where he was appointed Demonstrator in Animal Morphology in 1881, and Senior Lecturer in Animal Morphology in 1892. During 1887-1888 he also served as volunteer naturalist on the surveying voyage of to Christmas Island in the Indian Ocean, where he made valuable collections. He is commemorated in the specific epithet of an orchid (''Phreatia listeri'' ), Lister's palm (''Arenga listeri'' ), the Christmas Island lantern flower (''Abutilon listeri'' ), and Lister's gecko (''Lepidodactylus listeri'' ). He is al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Orchid
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] |
