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 along th ...

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 Pageand Plants of the World Online published by the Royal Botanic Gardens, Kew. This list is reflected on Wikispecies Species:Orchidaceae, Orchidaceae and the new eMonocot websitOrchidaceae Juss. This Taxonomy (biology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved/bent back or has a deeply grooved indentation, which serves to grab, latch or in any way attach itself onto another object. The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's ''shank'') or a ring (sometimes called the hook's "''eye''") for attachment to a thread (yarn), thread, rope or chain, providing a reversible attachment between two objects. In many cases, the distal end of the hook is sharply pointed to enable penetration into the target material, providing a firmer anchorage. Some hooks, particularly fish hooks, also have a ''barb'', a backwards-pointed projection near the pointed end that functions as a secondary "mini-hook" to catch and trap surrounding material, ensuring that the hook point cannot be easily pulled back out once e ...

Townsonia Viridis
''Townsonia viridis'', commonly known as the beech orchid, is a species of orchid endemic to Tasmania. It forms diffuse colonies with tiny, inconspicuous flowers and small, more or less round leaves and grows mainly in mossy places in myrtle beech forest. Description ''Townsonia viridis'' is a terrestrial, perennial, deciduous, sympodial herbs which grows in small groups with the tubers connected by a fleshy root. It spreads through mossy patches and leaf litter. Each tuber produces one or two leaves. Both flowering and non-flowering plants have an erect, very thin leaf emerging at ground level. These leaves are pale green to yellowish and have wavy margins. They are long and wide with a petiole long. Flowering plants also have a similar leaf on the flowering stem except that it lacks a petiole and is well above ground level. Up to four flowers long and wide are borne on a brittle, fleshy flowering stem high. The flowers are green with red blotches. The dorsal sepal is lon ...

David L
David (; , "beloved one") was a king of ancient Israel and Judah and the Kings of Israel and Judah, third king of the Kingdom of Israel (united monarchy), United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Canaanite and Aramaic inscriptions, Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as "Davidic line, House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the ''Seder Olam Rabbah'', ''Seder Olam Zutta'', and ''Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, Historicity of the Bible, the historicit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rchb
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist, ornithologist and illustrator. 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, becoming a professor and, eight years later in 1818, an instructor. 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. Together with Carl Friedrich Heinrich Schubert he started in 1822 to edit and distribute his first exsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

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 associated. 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 ...
