Townsonia Apetala
''Townsonia'', commonly called myrtle beech orchids is a genus of two species of flowering plants from the orchid family, Orchidaceae. They form small clusters of plants with their tubers connected, each tuber with one or two leaves. The flowers are inconspicuous. Description Orchids in the genus ''Townsonia'' are terrestrial, perennial, deciduous, sympodial herbs which grow in small groups with their tubers connected by a fleshy root. Each tuber produces one or two leaves. The leaves are very thin with wavy margins. Those on non-flowering plants have a relatively long, fleshy petiole near ground level. Flowering plants have a similar leaf but lack a petiole, the leaf on the side of a brittle flowering stem. The flowers are small and pale coloured and have a dorsal sepal wider than the lateral sepals. The petals are much smaller than the sepals. The labellum is much different in size and shape from the petals and sepals, folded lengthwise with a narrow, ridge-like callus al ...

Townsonia Deflexa
''Townsonia deflexa'', commonly known as the creeping forest orchid, is a species of orchid endemic to New Zealand. It forms diffuse colonies with tiny, inconspicuous flowers and small, more or less round leaves and grows mainly in mossy places in beech forest. Description ''Townsonia deflexa'' is a terrestrial, perennial, deciduous, sympodial herb which grows in small groups with its tubers connected by a fleshy root. It spreads through mossy patches and leaf litter, each tuber producing one or two leaves. The leaves of both flowering and non-flowering plants are very thin with wavy margins and a relatively long petiole. The leaves emerge at ground level and are egg-shaped to almost round, and about long. Flowering plants also have a similar leaf on the flowering stem except that it lacks a petiole. Up to four flowers about long are borne on a flowering stem high. The flowers are green with red blotches. The sepals are V-shaped in cross section, the dorsal sepal broader ...

List Of Orchidaceae Genera
This is a list of genera in the orchid family ( Orchidaceae), originally according tThe Families of Flowering Plants- L. Watson and M. J. Dallwitz. This list is adapted regularly with the changes published in the ''Orchid Research Newsletter'' which is published twice a year by the Royal Botanic Gardens, Kew. The most up to date list of accepted; genera, natural nothogenera, species and natural nothospecies with their synonyms can be found on the World Checklist of Selected Plants FamilieSearch Pagepublished by the Royal Botanic Gardens, Kew. This list is reflected on Wikispecies Orchidaceae and the new eMonocot websitOrchidaceae Juss. This taxonomy undergoes constant change, mainly through evidence from DNA study. Orchids were traditionally defined by morphological similarity (structure of their flowers and other parts). However, recent changes to nomenclature have been driven primarily by DNA studies and also by re-examination of herbarium specimens. This has led to a reductio ...

Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Rchb
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
