Grevillea Rara
''Grevillea rara'', also known as the rare grevillea, is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of the South West region of Western Australia. It is a prostrate, sprawling shrub when young, later a dense, prickly shrub with pinnatisect leaves with linear lobes, and clusters of white to pale pink flowers. Description ''Grevillea rara'' is a prostrate, sprawling shrub when young, later a dense, spreading, prickly shrub up to high and wide with woolly-hairy branchlets. The leaves are long, up to wide and pinnatisect with 3 to 5 lobes that are sometimes divided again, the end lobes linear long and wide. The edges of the leaf lobes are rolled under, obscuring the lower surface. The flowers are arranged in more or less spherical to dome-shaped clusters on a woolly-hairy rachis, and are white, sometimes tinged with pink, the pistil long. Flowering occurs from August to November and the fruit is an oblong follicle. The specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kings Park, Perth
Kings Park, (Noongar: ''Kaarta Gar-up'') is a park overlooking Perth Water and the central business district of Perth, Western Australia.

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Endemic Flora Of Western 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season.

Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Government of Western Australia, Western Australian government department responsible for managing lands and waters described in the ''Conservation and Land Management Act 1984'', the ''Rottnest Island Authority Act 1987'', the ''Swan and Canning Rivers Management Act 2006'', the ''Botanic Gardens and Parks Authority Act 1998'', and the ''Zoological Parks Authority Act 2001'', and implementing the state's conservation and environment legislation and regulations. The Department reports to the Minister for Environment and the Minister for Tourism. DBCA was formed on 1 July 2017 by the merger of the Department of Parks and Wildlife (Western Australia), Department of Parks and Wildlife (DPaW), the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rottnest Island Authority.

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

Acacia Pulchella
''Acacia pulchella'', commonly known as prickly moses or western prickly moses, is a shrub in the family Fabaceae.

Xanthorrhoea Preissii
''Xanthorrhoea preissii'', known as balga, is a widespread species of perennial monocot in Southwest Australia. Description The form of the plant resembles a tree, with very long and bunched, grass-like, leaves that emerge from a central base. The trunk may grow over 3 metres tall, and the often blackened appearance is evidence of its ability to withstand fire. The remains of the flammable leaves and the annual regrowth produce banding, allowing the age of the plant to be determined, and giving a record of previous fires in its habitat. The inflorescence appears on an upright spike, 1.5 m to 2.5 m long, between June and December. The sessile flowers, creamy or white, appear more profusely when stimulated by bushfire. Taxonomy The name 'balga' is derived from the Nyungar language. This species and other members of the genus ''Xanthorrhoea'' are informally termed blackboys or grasstrees. The appearance of the plant was seen as resembling a native inhabitant holding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hakea Lasiantha
''Hakea lasiantha'', commonly known as the woolly-flowered hakea, is a shrub in the family Proteaceae endemic to an area along the south coast in the South West and Great Southern regions of Western Australia. Description The erect non-lignotuberous dense rounded shrub typically grows to a height of . It blooms from May to September and produces white flowers and have woolly white or yellowish brown perianths with a deep red style in clusters in the leaf axils. The leaves are flat, elliptic or obovate, about long by young leaves and branchlets are clothed in rusty-woolly hairs. The smooth narrowly elliptic fruit are normally 2.5–3 cm (1 inch) long and only a slight beak. Taxonomy and naming ''Hakea lasiantha'' was first formally described by Scottish botanist Robert Brown in 1830. The specific name is derived from ancient Greek words ''lasios'' (λάσιος) meaning "shaggy" and ''anthos'' (ἄνθος) meaning flower,Backer, C.A. (1936). ''Verklarend woordenboek d ...
