Calectasia Grandiflora
''Calectasia grandiflora'', commonly known as the blue tinsel lily, is a plant in the family Dasypogonaceae growing as a perennial herb endemic to the south-west of Western Australia. It flowers in spring. Description ''Calectasia grandiflora'' is a rhizomatous perennial herb growing to a height of about 60 cm (24 in). The stems have many side branches and bear leaves 5.2–16.5 x 0.4–1.2 mm. The six petals are blue but turn red as they age; the central anthers are yellow and do not change colour as they age, unlike those of some other ''Calectasia'' species. Flowers appear from June to October (Winter and Spring) overall, though earlier in Perth than in the wheatbelt and Stirling Ranges. Taxonomy and naming ''Calectasia grandiflora'' is one of eleven species in the genus ''Calectasia''. It was first described by Ludwig Preiss in ''Plantae Preissianae'' in 1846. The specific epithet (''grandiflorum'') is from the Latin ''grandis'' = great and ''floris'' = ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Preiss
Johann August Ludwig Preiss (21 November 1811 – 21 May 1883) was a German-born British botanist and zoologist. Early life Preiss was born in Herzberg am Harz. He obtained a doctorate, probably at Hamburg, then emigrated to Western Australia. Australia Preiss was one of a number of influential German-speaking residents such as William Blandowski, Ludwig Becker, Hermann Beckler, Amalie Dietrich, Diedrich Henne, Gerard Krefft, Johann Luehmann, Johann Menge, Carl Ludwig Christian Rümker (a.k.a. Ruemker), Moritz Richard Schomburgk, Richard Wolfgang Semon, George Ulrich, Eugene von Guérard, Robert von Lendenfeld, Ferdinand von Mueller, Georg von Neumayer, and Carl Wilhelmi who brought their "epistemic traditions" to Australia, and not only became "deeply entangled with the Australian colonial project", but also "intricately involved in imagining, knowing and shaping colonial Australia" (Barrett, et al., 2018, p.2). He arrived at the Swan River Colony on board the ''Bri ... [...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.

Commelinids Of Australia
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, and no ...

Warren (biogeographic Region)
Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of ''Eucalyptus diversicolor'' (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906. Geography and geology The Warren region is defined as the coastal sandplain between Cape Naturaliste and Albany. Extending from the ocean to the edge of the Yilgarn craton p ...

Mallee (biogeographic Region)
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...

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.

Esperance, Western Australia
Esperance is a town in the Goldfields–Esperance region of Western Australia, on the Southern Ocean coastline approximately east-southeast of the state capital, Perth. The urban population of Esperance was 12,145 at June 2018. Its major industries are tourism, agriculture, and fishing.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
