Paul Graham Wilson
Paul Graham Wilson (born 1928) is an Australian botanist. He has been a most prolific contributor to the journal ''Nuytsia'', contributing to the first issue in 1970 and to the 12th volume in 1998, which was dedicated to him for his contributions to plant taxonomy and to celebrate his 70th birthday. Since his retirement from the Western Australian Herbarium in 1993, he has helped to maintain a comprehensive census of the flora of Western Australia. Wilson has mostly published papers dealing with the plant families Rutaceae, Asteraceae and Chenopodiaceae. Selected publications * A taxonomic revision of the genera ''Crowea'', ''Eriostemon'', and ''Phebalium'' (Rutaceae) * A taxonomic review of the genera ''Eriostemon'' and ''Philotheca ''Philotheca'' is a genus of about fifty species of flowering plants in the family Rutaceae.

Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', ''Aegiceras'', ''Aegialitis'' and ''Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vacuola ...

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 ...

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 ...

Swan Coastal Plain
The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean. The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia (IBRA) regions.IBRA Version 6.1

It is also one of the distinct physiographic provinces of the larger West Australian Shield division.


Location and description

The coastal plain is a strip on the Indian Ocean coast directly west of the

Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest. Considerable amount of research delineates northern, central and southern jarrah forestStrelein, G. J. (1988) ''Site classification in the Southern jarrah forest of Western Australia'' Como, W.A.

Whicher Range
Whicher Range, also known as Whicher Scarp, is a range in the South West region of Western Australia. The range has an average elevation of above sea level. Bounded by the Swan Coastal Plain to the west and the south, the Darling Scarp to the north and the Blackwood Plateau to the east, the range is approximately south of Busselton. The range has the form of a crescent shaped scarp. Composed of lateritic Mesozoic sediments, the range marks the southern and western edge of the Yilgarn Block. Ecological fragility The range is also the location of endemic rare flora and this had been identified in the 1970s. It has also been surveyed more recently in 2008, showing that further interest in the range's floristic uniqueness deserved more study. The most critically endangered species that inhabits the Whicher range is '' Petrophile latericola'' also known as Laterite petrophile, Ironstone Petrophile or the Ironstone Pixie Mop, which has a range of approximately within ...

Capel, Western Australia
Capel is a town in the South West region of Western Australia, located south of Perth and midway between Bunbury and Busselton. The town is located on the Capel River and is approximately above sea level. History The Capel area was originally inhabited by the Wardandi Noongar people. Colonists visited the region early in the history of colonial Western Australia. The Capel River was visited by Frederick Ludlow in 1834, but it was not given an English name until the Bussell family settled in the area soon afterwards. The name honours Capel Carter Brockman (1839–1924), daughter of John Bussell (1803–1875), herself named after a Miss Capel Carter, a cousin of the Bussells in England with whom Bussell family members corresponded. In the 1830s a number of settlers followed the Bussells into the area, and both James Stirling and John Hutt, (the first two Governors of Western Australia) took up land in the region. Plans to establish a townsite in the area were first ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ...
