Hakea Pendens
''Hakea pendens'' is a flowering plant in the family ''Proteaceae'' and endemic to a small area in the Goldfields-Esperance regions of Western Australia. It is a small shrub with needle-like leaves and pendulous pink flowers. Description ''Hakea pendens'' typically grows to high and wide. The branchlets are densely covered in silky, flattened hairs until flowering and then the surface becoming whitish and waxy. The terete, dark green leaves are long and about wide, crowded, stiff, and densely covered with silky, rusty coloured, flattened hairs, ending with a sharp point long. The inflorescence is a cluster of 6-8 pale pink pendulous flowers borne in leaf axils. Flowering occurs from August to September and the fruit is obovate, smooth, grey, sometimes with darker grey speckling and about long and wide. Taxonomy and naming ''Hakea pendens'' was first formally described in 1990 by Robyn Mary Barker and the description was published in the ''Journal of the Adelaide Botanic G ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terete
Terete is a term in botany used to describe a cross section that is circular, or like a distorted circle, with a single surface wrapping around it.Lichen Vocabulary, Lichens of North America Information, Sylvia and Stephen Sharnoff/ref> This is usually contrasted with cross-sections that are flattened, with a distinct upper surface that is different from the lower surface. The cross-section of a branch in a tree is somewhat round, so the branch is terete. The cross section of a normal leaf has an upper surface, and a lower surface, so the leaf is not terete. However, the fleshy leaves of succulents are sometimes terete. Fruticose lichens are terete, with a roughly circular cross section and a single wrap-around skin-like surface called the cortex, compared to foliose lichens and crustose lichens Crustose lichens are lichens that form a crust which strongly adheres to the substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Obovate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marvel Loch, Western Australia
Marvel Loch is a small townsite of fewer than 100 people, east of Perth, Western Australia. It is located south west of Southern Cross, along the Perth to Kalgoorlie Great Eastern Highway. The town is located in the Shire of Yilgarn. Gold was discovered in the area in the early 1890s. In 1906 following gold mining leases being issued to Markham, Doolette, Leneberg and Le Breton, who named their lease Marvel Loch. The town is named after the horse that won the Caulfield Cup in 1905. The town lies between the mine and another minesite, and the current location was surveyed in 1909 and the town was gazetted in 1911. The Marvel Loch Progress Association was formed in 1909 to help get a School established in the area, which was built by the Association in around 1910 out of Lime Wash Hession Walls with Bush Poles and an Iron Roof. In 1911 with attendance growing resulted in a bigger building being built in 1911. Tianye SXO Gold Mining currently operate the Marvel Loch Gold Mine i ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
