Pterostylis Alata
''Pterostylis alata'', commonly known as the striped greenhood, is a species of orchid endemic to Tasmania. As with similar orchids, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves but the flowering plants have a single flower with leaves on the flowering spike. This greenhood has a white flower with prominent dark green stripes and a sharply pointed, brown-tipped dorsal sepal. Similar greenhoods growing on the Australian mainland were formerly known as ''Pterostylis alata'' but are now given the name ''Pterostylis striata''. Description ''Pterostylis alata'' is a terrestrial, perennial, deciduous, herb with an underground tuber and when not flowering, a rosette of dark green, wrinkled leaves, long and wide. Flowering plants have a single flower long and wide borne on a spike high. The flowers are white with dark green stripes. The dorsal sepal and petals are fused, forming a hood or "galea" over the column ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Orchids Of Australia
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterostylis
''Pterostylis'' is a genus of about 300 species of plants in the orchid family, Orchidaceae. Commonly called greenhood orchids, they are terrestrial, deciduous, perennial, tuberous, herbs found in Australia, New Zealand, New Guinea, New Caledonia and one Indonesian island. The flowers are mostly green, sometimes with brown, reddish or white stripes, and are distinguished from other orchids by their unusual flower structures and pollination mechanism. Description Greenhood orchids are all terrestrial herbs with an underground tuber like many other genera of orchids but are distinguished by a hood-like "galea" formed by the fusing of the dorsal sepal and two lateral petals. The galea curves forward, covers the sexual parts of the flower, is important in the pollination process and is about as long as the two petals. The dorsal sepal is translucent white with green, reddish or brown stripes. The two lateral sepals are joined at their base, form the front of the flower and usually ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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] |
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] |
Novae Hollandiae Plantarum Specimen
''Novae Hollandiae Plantarum Specimen'' is a two-volume work describing the flora of Australia. Facsimiles of the originals can be found in the onlinBiodiversity Heritage Library (Vol.1)anVol 2) The author was the French botanist Jacques Labillardière, who visited the region in 1792 with the d'Entrecasteaux expedition. Published between 1804 and 1806, it is one of the earliest works to describe the plants of the continent; according to Denis and Maisie Carr, " practical terms, this was the first general flora of Australia." The work describes the botanical collections made by himself and his companion on the d'Entrecasteaux expedition, Charles Riche, and the unattributed and later collections of Nicolas Baudin's expedition. Labillardière's collections were seized by the English, but were returned to him in France at the intervention of Joseph Banks. He made his collections at Observatory Island and other locations at the Archipelago of the Recherche. Extensive collection were ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disperis
''Disperis'' is a genus of plants in the orchid family, Orchidaceae. It has about 78 species.Mark W. Chase, Kenneth M. Cameron, John V. Freudenstein, Alec M. Pridgeon, Gerardo A. Salazar, Cássio van den Berg, and André Schuiteman. 2015. "An updated classification of Orchidaceae". ''Botanical Journal of the Linnean Society'' 177(2):151-174. (See ''External links'' below). Most of the species are from tropical and southern Africa, as well as Indian Ocean islands. A few are native to the tropical or the warmer subtropical regions of Asia and Malesia. Etymology The genus name ''Disperis'' derives from the ancient greek (), meaning "twice", and (), meaning "bag", "pouch", because of to the pouches formed by the lateral sepals.Umberto Quattrocchi. 2000.

Jacques Labillardière
Jacques-Julien Houtou de Labillardière (28 October 1755 – 8 January 1834) was a French biologist noted for his descriptions of the flora of Australia. Labillardière was a member of a voyage in search of the Jean-François de Galaup, comte de Lapérouse, La Pérouse expedition. He published a popular account of his journey and produced the first Flora (publication), Flora on the region. Early life Jacques Labillardière was born in Alençon, Normandy, France, on 28 October 1755. The ninth of 14 children of a lace merchant, he was born into a devoutly Roman Catholic family of modest means.Duyker (2003) p. 8. The surname ''Labillardière'' originated with Labillardière's grandfather, Jacques Houtou, who, in an affectation of nobility, appended the name of the family's estate, ''La Billardière'', after his surname. Labillardière was thus baptised under the surname ''Houtou de Labillardière'', but he later dropped the patronymic, retaining only ''Labillardière'' in both h ...
