Guioa Semiglauca
''Guioa semiglauca'', known as the guioa or wild quince, is a rainforest tree of eastern Australia. It grows from Kioloa (35° S) near Batemans Bay in southern New South Wales to Eungella National Park (20° S) in tropical Queensland. It grows in many different types of rainforest, particularly common in regenerating areas and on sand in littoral rainforest. Description Growing to around 20 metres tall, and 43 cm in diameter, though often seen much smaller than this. The outer bark is smooth, often coloured and patterned by various lichens. The outer bark is similar to coachwood, however it is more fluted and irregular. The veiny leaflets are pinnate 5 to 10 cm long. The midrib extends beyond the leaf to form a tiny tip. Green above, whitish glaucous below. The yellow/green flowers form around September to November. The fruiting capsule matures from January to May. The seeds are oval covered by a thin layer of fleshy aril. Fruit eaten by a large variety of birds, ...

Hacking River
The Hacking River is a perennial stream, watercourse that is located in the Southern Sydney region of New South Wales in Australia. For thousands of years traditional owners called the river Deeban, however the colonial settlers renamed the river after Henry Hacking, a British seaman who killed Pemulwuy and was a Maritime pilot, pilot at Port Jackson in colonial New South Wales. Course Drawing its source from the east north-eastern runoff of the Illawarra escarpment, drained via Kellys Creek and Gills Creek, both terminating in falls adjacent to each other. The waters of both creeks combine in the valley below, forming the Hacking River. Kellys Creek rises about south of , east of the Princes Highway and west of . The Hacking River flows generally north north-east before reaching its Mouth (river), mouth and emptying into Port Hacking at a line between Grays Point and Point Danger, about east of the suburb of , west of . The river descends over its Watercourse, course. Alt ...

Aril
An aril (pronounced ), also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. An arillode or false aril is sometimes distinguished: whereas an aril grows from the attachment point of the seed to the ovary (from the funiculus or '' hilum''), an arillode forms from a different point on the seed coat. The term "aril" is sometimes applied to any fleshy appendage of the seed in flowering plants, such as the mace of the nutmeg seed. Arils and arillodes are often edible enticements that encourage animals to transport the seed, thereby assisting in seed dispersal. Pseudarils are aril-like structures commonly found on the pyrenes of Burseraceae species that develop from the mesocarp of the ovary. The fleshy, edible pericarp splits neatly in two halves, then falling away or being eaten to reveal a brightly coloured pseudaril around the black seed. The aril may create a fruit-like structure, called (among other names) a ''false fruit ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

Sapindales Of Australia
Sapindales is an order of flowering plants. Well-known members of Sapindales include citrus; maples, horse-chestnuts, lychees and rambutans; mangos and cashews; frankincense and myrrh; mahogany and neem. The APG III system of 2009 includes it in the clade malvids (in rosids, in eudicots) with the following nine families: *Anacardiaceae *Biebersteiniaceae *Burseraceae *Kirkiaceae *Meliaceae *Nitrariaceae (including Peganaceae and Tetradiclidaceae) *Rutaceae *Sapindaceae *Simaroubaceae The APG II system of 2003 allowed the optional segregation of families now included in the Nitrariaceae. In the classification system of Dahlgren the Rutaceae were placed in the order Rutales, in the superorder Rutiflorae (also called Rutanae). The Cronquist system of 1981 used a somewhat different circumscription, including the following families: *Staphyleaceae *Melianthaceae * Bretschneideraceae *Akaniaceae *Sapindaceae *Hippocastanaceae *Aceraceae *Burseraceae *Anacardiaceae *Julianiaceae ...

Kiama
Kiama () is a coastal town 120 kilometres south of Sydney in the Illawarra. One of the main tourist attractions is the Kiama Blowhole. Kiama features several popular surfing beaches and caravan parks, and numerous alfresco cafes and restaurants. Its proximity to the south of Sydney makes it an attractive destination for many day-trippers and weekenders. History Kiama was the site of two strong volcanic flows, called the Gerringong Volcanics, which came out of Saddleback Mountain, now a collapsed volcanic vent. The Kiama Blowhole is part of an erosion process on the more recent rock, formed into columnar basalt, or latite. Before the cedar-getters (comprising ex-convicts, convicts and runaways, some with cedar licences and many without) arrived in the area around 1810, the local Indigenous Australians, Wodi Wodi of the language group Dharawal, had been using the land for thousands of years, moving every six weeks or so in family groups. This is supported by a midden of shells ...

Saponin
Saponins (Latin "sapon", soap + "-in", one of), also selectively referred to as triterpene glycosides, are bitter-tasting usually toxic plant-derived organic chemicals that have a foamy quality when agitated in water. They are widely distributed but found particularly in soapwort (genus Saponaria), a flowering plant, the soapbark tree (''Quillaja saponaria'') and soybeans (''Glycine max'' L.). They are used in soaps, medicinals, fire extinguishers, speciously as dietary supplements, for synthesis of steroids, and in carbonated beverages (the head on a mug of root beer). Structurally, they are glycosides, sugars bonded to another organic molecule, usually a steroid or triterpene, a steroid building block. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin, licorice flavoring; and quillaia (alt. quillaja), a bark extract used in beverages. Uses The saponins are a subclass of terpenoids, the larges ...

Indigenous Australians
Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

Australian King Parrot
The Australian king parrot (''Alisterus scapularis'') is a species of parrot endemic to eastern Australia ranging from Cooktown in Queensland to Port Campbell in Victoria. Found in humid and heavily forested upland regions of the eastern portion of the continent, including eucalyptus wooded areas in and directly adjacent to subtropical and temperate rainforest. They feed on fruits and seeds gathered from trees or on the ground. Taxonomy The Australian king parrot was first described by the German naturalist Martin Lichtenstein in 1818 as ''Psittacus scapularis''. The species belongs to the genus '' Alisterus'', whose three members are also known as king parrots. The species are sometimes allied to the genus '' Aprosmictus''. Two subspecies are recognised, which are differentiated by size: **''A. s. minor'' (Mathews, 1911) **''A. s. scapularis'' (Lichtenstein, 1816) Naturally-occurring hybrids with the red-winged parrot (''Aprosmictus erythropterus'') have been recorded from Be ...

Glaucous
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by insec ...
