Pterostylis Major
''Pterostylis major'' is a plant in the orchid family Orchidaceae and is endemic to New South Wales where it grows on the Northern Tablelands. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves on a short stalk but the flowering plants lack a rosette and have up to eleven well-spaced, bright green flowers with darker stripes, on a flowering stem with stem leaves. Description ''Pterostylis major'' is a terrestrial, perennial, deciduous, herb with an underground tuber. Non-flowering plants have a rosette of between three and six leaves, each leaf long and wide on a stalk high. Flowering plants lack a rosette but have up to eleven flowers on a flowering spike high with between five and seven linear to lance-shaped stem leaves which are long and wide. The flowers are well-spaced, long, wide and translucent bright green with darker green stripes. The dorsal sepal and petals are joined ...

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 ...

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 ...

Barrington Tops National Park
The Barrington Tops National Park is a protected national park located in the Hunter Valley in New South Wales, Australia. Gazetted in 1969, the park is situated between Scone, Singleton, Dungog, Gloucester and East Gresford. The park is part of the Barrington Tops group World Heritage Site Gondwana Rainforests of Australia inscribed in 1986 and added to the Australian National Heritage List in 2007. It is also part of the Barrington Tops and Gloucester Tops Important Bird Area. Environment Geology Barrington Tops is part of the Mount Royal Range, a spur of the Great Dividing Range. Barrington Tops is a plateau between two of the large peaks in the range. The park is believed to be an extinct volcano and the mountain ranges are made up of a mixture of sedimentary rocks with a granite top. Erosion has weathered the granite and rounded granite boulders can be seen in some areas of the park. Estimates put the age of the rock at 300 to 400 million years, well before Australia sep ...

New England (New South Wales)
New England is a vaguely defined region in the north of the state of New South Wales, Australia, about 60 km inland from the Tasman Sea. The area includes the Northern Tablelands (or New England Tablelands) and the North West Slopes regions. As of 2006, New England had a population of 202,160, with over a quarter of the people living in the area of Tamworth Regional Council. Shaw, John H., "Collins Australian Encyclopedia", William Collins Pty Ltd., Sydney, 1984, . History The region has been occupied by Indigenous Australians for tens of thousands of years, in the west by the Kamilaroi people. In the highlands, the original languages (which are now extinct) included Anaiwan to the south of Guyra and Ngarbal to the north of Guyra. The population of the tablelands has been estimated to be 1,100 to 1,200 at the time of colonisation – quite low in comparison to the Liverpool Plains and Gwyder River region, estimated to be 4,500 to 5,500.

Pterostylis Longifolia
''Pterostylis longifolia'', commonly known as the common leafy greenhood or tall greenhood, is a plant in the orchid family Orchidaceae and is Endemism, endemic to eastern Australia. Flowering plants have up to seven flowers which are green, partly transparent and which have a Labellum (botany), labellum which is pale green and hairy with a blackish central stripe. Non-flowering plants have a Rosette (botany), rosette of leaves but flowering plants lack the rosette, instead having five to eight stem leaves. A similar species, ''Pterostylis melagramma'' has paler green flowers which have a less hairy Labellum (botany), labellum. Description ''Pterostylis longifolia'', is a terrestrial, Perennial plant, perennial, deciduous, Herbaceous plant, herb with an underground tuber. Non-flowering plants have a rosette of between three and six, linear to lance-shaped leaves, each leaf long and wide. Flowering plants have up to seven green, partly transparent flowers on a flowering spike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
