Dodonaea petiolaris | |
Dodonaea petiolaris is a shrub species in the genus Dodonaea found in Australia.
It is an erect shrub, 1–2(–5) m high living on sandy and loamy soils, on rocky hillsides and ridges. [1] The seed possesses a water gap explaining its dormancy. [2]
Dodonaea petiolaris yields the diterpene ent-3β-acetoxy-15,16-epoxylabda-8(17),13(16),14-trien-18-oic acid (C22H28O6) or its enantiomer. [3]
The species occurs in Western Australia, South Australia, the Northern Territory, Queensland and New South Wales. [4]
Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. They are found in a wide variety of landscapes; sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
Acacia aneura, commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia. It is the dominant tree in the habitat to which it gives its name (mulga) that occurs across much of inland Australia. Specific regions have been designated the Western Australian mulga shrublands in Western Australia and Mulga Lands in Queensland.
Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory.
Hakea is a genus of about 150 species of plants in the Family Proteaceae and are endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially Grevillea. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia.
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination of non-dormant seeds.
Dodonaea is a genus of about 70 species of flowering plants, often known as hop-bushes, in the soapberry family, Sapindaceae. It has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia. By far the highest species diversity is in Australia. The genus is named after Rembert Dodoens, traditionally known as 'Dodonaeus'.
Banksia petiolaris is a rare species of flowering plant in the family Proteaceae native to Western Australia, where it is found in sandy soils in the south coastal regions from Munglinup east to Israelite Bay. It was first described by Victorian state botanist Ferdinand von Mueller in 1864, and no subspecies are recognised. B. petiolaris is one of several closely related species that will all grow as prostrate shrubs, with horizontal stems and thick, leathery upright leaves. Those of this species can be viable for up to 13 years—the longest-lived of any flowering plant recorded. It bears yellow cylindrical flower spikes, known as inflorescences, up to 16 cm high in spring. As the spikes age, they turn grey and develop up to 20 woody seed pods, known as follicles, each.
Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.
Banksia blechnifolia is a species of flowering plant in the genus Banksia found in Western Australia. It was first described by Victorian state botanist Ferdinand von Mueller in 1864, and no subspecies are recognised. It gained its specific name as its leaves are reminiscent of a fern (Blechnum). B. blechnifolia is one of several closely related species that grow as prostrate shrubs, with horizontal stems and leathery, upright leaves. The red-brown flower spikes, known as inflorescences, are up to 20 centimetres (8 in) high and appear from September to November in the Australian spring. As the spikes age, each turns grey and develops as many as 25 woody seed pods, known as follicles.
Muntingia is a genus of plants in the family Muntingiaceae, comprising only one species, Muntingia calabura, and was named in honour of Abraham Munting. It is native to the neotropics, from Mexico south to Bolivia, with edible fruit, and has been widely introduced in other tropical areas.
Hakea petiolaris, commonly known as the sea-urchin hakea, is a shrub or small tree with cream-coloured and pink or purple flowers and woody fruit. It is endemic to the south west of Australia, occurring at the coastal plain, jarrah forest and wheatbelt regions, often at the ancient granite outcrops of Western Australia.
Atriplex cinerea, commonly known as grey saltbush, coast saltbush, barilla or truganini, is a plant species in the family Amaranthaceae. It occurs in sheltered coastal areas and around salt lakes in the Australian states of Western Australia, South Australia, Tasmania, Victoria and New South Wales.
Banksia gardneri var. gardneri is a variety of Banksia gardneri. As an autonym, it is defined as encompassing the type material of the species. It is native to the Southwest Botanical Province of Western Australia.
Drosera falconeri is a carnivorous plant in the genus Drosera. It is endemic to the Northern Territory of Australia.
Dodonaea microzyga, commonly known as brilliant hopbush, is a shrub in the family Sapindaceae. It grows to between 0.3 and 1.5 metres high.
Hakea leucoptera, commonly known as silver needlewood, needle hakea, pin bush or water tree and as booldoobah in Koori language, is a shrub or small tree with rigid, cylindrical, sharply pointed leaves and white, cream-coloured or yellow flowers in late spring and early summer. It is widespread and common in central parts of the Australian mainland.
Grevillea kennedyana is a sprawling shrub of the genus Grevillea. It is only found in a small part of Australia, with a natural range less than 100 km. It is considered a vulnerable under federal and state legislation. G. kennedyana is also known as the flame spider-flower.
Persoonia terminalis, also known as the Torrington geebung, is a rare shrub belonging to the family Proteaceae, and native to northern New South Wales and southern Queensland in eastern Australia. Reported as a subspecies of Persoonia nutans in 1981, it was described as a species by Lawrie Johnson and his colleague Peter Weston in 1991.
Isopogon mnoraifolius is a shrub of the family Proteaceae and is endemic to New South Wales.
Dodonaea procumbens, commonly known as the creeping hop bush, is a species of shrub in the genus Dodonaea found in eastern Australia. It was one of eleven species selected for the Save a Species Walk campaign in April 2016; scientists walked 300 km to raise money for collection of seeds to be prepared and stored at the Australian PlantBank at the Australian Botanic Garden, Mount Annan.
