Argophyllum Nullumense
''Argophyllum nullumense'', the silver leaf, is a shrub or small tree found in eastern Australia. A rare plant with a ROTAP rating of 3RCa The generic name comes from the Greek, meaning "bright leaf", referring to the silvery white under-side of the leaves. The original specimen was collected from Mount Nullum, near Murwillumbah. It grows from near Nimbin in the south to Mackay, Queensland. Most often seen on the Mount Warning caldera, growing in warm temperate rainforest based on the relatively infertile rhyolite based soils. Growing to 8 metres tall and a stem diameter of 15 cm. The plant often branches close to the ground. Yellow flowers form on terminal panicle A panicle is a much-branched inflorescence. (softcover ).

ROTAP
Rare or Threatened Australian Plants, usually abbreviated to ROTAP, is a list of rare or threatened Australian plant taxa. Developed and maintained by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the most recent edition lists 5031 taxa. The list uses a binary coding system based on the IUCN Red List categories for "Presumed Extinct", "Endangered", "Vulnerable", "Rare" or "Poorly Known". However, it also provides for additional information such as geographic range and occurrence in protected areas. It was first compiled in 1979, and published in 1981, with revisions published in 1988 and 1996. In its early days it was the only nationally recognised list of threatened plants, although it had no legal status. When the ''Endangered Species Protection Act 1992'' was proclaimed, the ROTAP list was used as a basis for the publication of schedules to the Act. A third list was produced by ANZECC from 1996. In 2000, the ''Environment Protection and Biodiversity Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murwillumbah
Murwillumbah ( ) is a town in far north-eastern New South Wales, Australia, in the Tweed Shire, on the Tweed River. Sitting on the south eastern foothills of the McPherson Range in the Tweed Volcano valley, Murwillumbah is 848 km north-east of Sydney, 13 km south of the Queensland border and 132 km south of Brisbane. The town's name is often abbreviated to M'bah or Murbah. At the 2016 census, Murwillumbah had a population of 9,245. Many of the buildings are Art Deco in style and there are cafes, clothes shops and antique shops in the town. History The first people to live in the area were Kalibai people.

Nimbin, New South Wales
Nimbin is a village in the Northern Rivers area of the Australian state of New South Wales, approximately north of Lismore, northeast of Kyogle, and west of Byron Bay. Nimbin is notable for the prominence of its environmental initiatives such as permaculture, sustainability, and self-sufficiency, as well as the cannabis counterculture. Writer Austin Pick described his initial impressions of the village this way: "It is as if a smoky avenue of Amsterdam has been placed in the middle of the mountains behind frontier-style building facades. ... Nimbin is a strange place indeed." Nimbin has been described in literature and mainstream media as 'the drug capital of Australia', 'a social experiment', and 'an escapist sub-culture'. Nimbin has become an icon in Australian cultural history, with many of the values first introduced there by the counterculture becoming part of modern Australian culture. History Nimbin and surrounding areas are part of what was known as the "Rainbow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mackay, Queensland
} Mackay () is a city in the Mackay Region on the eastern or Coral Sea coast of Queensland, Australia. It is located about north of Brisbane, on the Pioneer River. Mackay is described as being in either Central Queensland or North Queensland, as these regions are not precisely defined. More generally, the area is known as the Mackay–Whitsunday Region. Mackay is nicknamed the sugar capital of Australia because its region produces more than a third of Australia's sugar. Name The city was named after John Mackay. In 1860, he was the leader of an expedition into the Pioneer Valley. Initially Mackay proposed to name the river Mackay River after his father George Mackay. Thomas Henry Fitzgerald surveyed the township and proposed it was called Alexandra after Princess Alexandra of Denmark, who married Prince Edward (later King Edward VII). However, in 1862 the river was renamed to be the Pioneer River, after in which Queensland Governor George Bowen travelled to the area, and t ...

Mount Warning
Mount Warning ( Bundjalung: ''Wollumbin''), a mountain in the Tweed Range in the Northern Rivers region of New South Wales, Australia, was formed from a volcanic plug of the now-gone Tweed Volcano. The mountain is located west-south-west of Murwillumbah, near the border between New South Wales and Queensland. Lieutenant James Cook saw the mountain from the sea and named it Mount Warning. Shield volcano Mount Warning is the central volcanic remnant of an ancient shield volcano, the Tweed Volcano, which would have been about above sea level or just under twice the height of the current mountain.The Caldera of the Mount Warning Shield Volcano. rochureNew South Wales National Parks and Wildlife Service. 1990.

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018.

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...

Lismore, New South Wales
Lismore is a city in northeastern New South Wales, Australia and the main population centre in the City of Lismore Local government in Australia, local government area; it is also a regional centre in the Northern Rivers region of the State. It is situated on a low flood plain on the banks of the Wilsons River (New South Wales), Wilsons River near the latter's junction with Leycester Creek, both tributaries of the Richmond River which enters the Pacific Ocean at Ballina, New South Wales, Ballina, to the east. The original settlement initially developed as a grazing property in the 1840s, then became a timber and agricultural town and inland port based around substantial river traffic, which prior to the development of the road and rail networks was the principal means of transportation in the region. Use of the river for transport declined and then ceased around the mid-twentieth century, however by that time Lismore (which was elevated to city status in 1946) had become well est ...
