Pterostylis Umbrina
''Pterostylis umbrina'', commonly known as the broad-sepaled leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to the Australian Capital Territory and New South Wales on the Southern Tablelands. As with similar greenhoods, plants in flower differ from those that are not. Those not in flower have a rosette of leaves flat on a short stalk. Plants in flower have up to six green flowers with darker green stripes with stem leaves but lack a rosette. Description ''Pterostylis diminuta'', is a terrestrial, perennial, deciduous, herb with an underground tuber. Plants not in flower have a rosette of between three and five, lance-shaped or elliptic leaves on a stalk tall, each leaf long and wide. When flowering, plants lack a rosette but have up to six flowers on a flowering spike high with four to seven linear to lance-shaped stem leaves that are long and wide. The flowers are long, wide. The dorsal sepal and petals are joined to form a hood c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aranda, Australian Capital Territory
Aranda () is a suburb in the district of Belconnen, in the Australian capital city of Canberra. Located at the western foot of Black Mountain and bounded on two sides by nature park, the suburb is characterised by its bush setting. During the planning and development of the suburb, a large proportion of large native trees – predominantly eucalypts – were left in place. The suburb derives its name from the Arrernte tribe of Central Australia, previously known as ''Arunta'', which means 'White Cockatoo'. The streets in Aranda are named after Aboriginal tribal groups from around Australia. The suburb comprises an area of 160ha and in 1967 was the first suburb in Belconnen to be settled. A small plaque at the Aranda District playing fields near the suspension bridge over Belconnen Way marks the settlement of the suburb as the first development in the Belconnen district. It reads: Location Aranda is located in the south east of Belconnen. It is bounded by Caswell Drive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Orchids Of New South Wales
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] |
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 ...

Tumut
Tumut () is a town in the Riverina region of New South Wales, Australia, situated on the banks of the Tumut River. Tumut sits on the north-west foothills of the Snowy Mountains and is located on the traditional lands of the Wiradjuri, Wolgalu and Ngunnawal Aboriginal peoples. Tumut is often referred to as the 'gateway to the snowy' Snowy Mountains Scheme. The former Tumut Shire was administered from offices located in the town. Tumut is approximately south-west of Sydney and north-east of Melbourne. Tumut is home to a number of historic buildings, including an Anglican church designed by Edmund Blacket and a Courthouse designed by James Barnet. Many of the pubs in the town have been in use from the mid to late 1800s. Early settlers established many European deciduous trees throughout the area. The stand of Poplars, Elm and Willow, amongst others, create a well renowned display of colour over autumn. Tumut celebrates this with the yearly Festival of the Falling Leaf. Etym ...

Burrinjuck, New South Wales
Burrinjuck is a village community in the far eastern part of the Riverina. It is situated by road, about 15 kilometres southwest from Woolgarlo and 28 kilometres south from Bookham. The name of the town is derived from an Aboriginal word meaning 'mountain with a rugged top'. At the , the Burrinjuck area had a population of 19. The village is situated on the western side of Burrinjuck Dam which holds water from the Murrumbidgee River and which was constructed between 1907 and 1928 (with World War I interfering with the timing of the construction). During the construction of the dam and in the time during which it filled, there was a settlement known as 'Barren Jack City' facing the river at the base of the Burrinjuck mountain. Much of its site was later submerged as the dam water rose. The locality of Burrinjuck includes part of one of the proposed sites for Australia's national capital, which was known as Mahkoolma. It was to be located in the upper reaches of nearb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

Pterostylis Macrosepala
''Pterostylis macrosepala'' is a plant in the orchid family Orchidaceae and is endemic to the central-west slopes of New South Wales. As with similar greenhoods, plants in flower differ from those that are not flowering. Non-flowering plants have a rosette of leaves flat on the ground, but those that are flowering have up to eight translucent green flowers with narrow, dark green stripes and up to ten stem leaves. Description ''Pterostylis macrosepala'', is a terrestrial, perennial, deciduous, herb with an underground tuber. Non-flowering plants have a rosette of between three and five, egg-shaped to lance-shaped leaves, each leaf long and wide with a petiole up to long. Plants that are flowering lack a rosette but have up to eight flowers on a flowering spike high with between five and ten linear to lance-shaped stem leaves that are long and wide.

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] |
