Petrophile Aculeata
''Petrophile aculeata'' is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a small shrub with narrow egg-shaped leaves with the narrower end towards the base and with irregular teeth near the end, and more or less spherical heads of hairy yellow flowers. Description ''Petrophile aculeata'' is a shrub that typically grows to a height of and has hairy branchlets and leaves but that become glabrous with age. The leaves are narrow egg-shaped with the narrower end towards the base, long and wide with irregular teeth in the upper half. The flowers are arranged in sessile, more or less spherical heads in diameter, with hairy grey involucral bracts at the base. The flowers are about long, yellow and hairy. Flowering occurs from October to November and the fruit is a nut, fused with others in a more or less spherical head up to in diameter.

Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coorow, Western Australia
Coorow is a town in the Mid West region of Western Australia, north of Perth. History The townsite of Coorow was gazetted in 1893. Its name is derived from the Aboriginal name of a nearby spring, first recorded in 1872. The meaning of the name may be from the word "Curro", which is the Aboriginal word for a variety of ''Portulaca''; another source gives it as "many mists". The town experienced some flooding in 1918 following a deluge of of rain overnight. The Moore River broke its banks and caused much more severe flooding downstream at Moora. After rapid growth through the early 1920s local settlers began to seek obtaining a hotel licence for the town in 1927. The licence was granted in 1929 to Alexander Gloster who put forward a tender of £1,750, and submitted his plans for approval. The hotel was erected at a cost of £13,000 and constructed of cement blocks and brick. The two storey building held fifteen rooms for accommodation on the top floor and more accommodation ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Petrophile
''Petrophile'' is a genus of evergreen shrubs, in the family Proteaceae. The genus is endemic to Australia. Commonly known as conebushes, they typically have prickly, divided foliage and produce prominently-displayed pink, yellow or cream flowers followed by grey, conical fruits. Taxonomy The genus ''Petrophile'' was first formally described in 1809 by Joseph Knight in ''On the cultivation of the plants belonging to the natural order of Proteeae'', preempting publication of the same name by Robert Brown in his book '' On the natural order of plants called Proteaceae''. The name ''Petrophile'' is derived from the Greek words ''petra'' = rock and ''philos'' = seeking or preferring, referring to the rocky habitat in which some species grow. Species list The following is a list of ''Petrophile'' species and subspecies accepted by the Australian Plant Census as at November 2020: *'' Petrophile acicularis'' R.Br.

Department Of Parks And Wildlife (Western Australia)
The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the ''Conservation and Land Management Act 1984'' and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment. History The Department of Environment and Conservation (DEC) was separated on 30 June 2013, forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), both of which commenced operations on 1 July 2013. DPaW focused on managing multiple use state forests, national parks, marine parks and reserves. DER focused on environmental regulation, approvals and appeals processes, and pollution prevention. It was announced on 28 April 2017 that the Department of Parks and Wildlife would merge with the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rott ...

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

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 ...
