Calytrix Uncinata
''Calytrix uncinata'' is a species of plant in the myrtle family Myrtaceae that is endemic to Western Australia. The shrub typically grows to a height of . It usually blooms between August and November producing white star-shaped flowers. Found on granite or sandstone breakaways, rocky rises in the central Mid West The Midwestern United States, also referred to as the Midwest or the American Midwest, is one of four census regions of the United States Census Bureau (also known as "Region 2"). It occupies the northern central part of the United States. I ... region of Western Australia where it grows on sandy clay soils. The species was first formally described by Lyndley Craven in 1990 in the article ''Three additional species in Calytrix (including the reduction of Calythropsis), and notes on Calytrix exstipulata (Myrtaceae).'' in the journal '' Australian Systematic Botany''.

Lyndley Craven
Lyndley Alan Craven (3 September 1945 – 11 July 2014) was a botanist who became the Principal Research Scientist of the Australian National Herbarium. Lyndley ("Lyn") Craven worked for the CSIRO plant taxonomy unit of the New Guinea Survey Group, Division of Land Research and Regional Survey from 1964 to 1967. This was part of a unit that became the Australian National Herbarium, Centre for Australian National Biodiversity Research. Craven's duties included botanical support for land resources surveys. Craven then left to study horticulture at Burnley Horticultural College, Victoria, earning the degree of Diploma of Horticultural Science in 1970 before being briefly employed by the Parks and Gardens Branch of Department of the Interior, Canberra. Part of this department later became the Canberra Botanic Garden and eventually the Australian National Herbarium, Centre for Australian National Biodiversity Research at the Australian National Botanic Gardens. In 1984, he earned the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

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] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Mid West (Western Australia)
The Mid West region is one of the nine regions of Western Australia. It is a sparsely populated region extending from the west coast of Western Australia, about north and south of its administrative centre of Geraldton, Western Australia, Geraldton and inland to east of Wiluna, Western Australia, Wiluna in the Gibson Desert. It has a total area of , and a permanent population of about 52,000 people, more than half of those in Geraldton. Earlier names The western portion of this region was known earlier as "The Murchison" based on the Murchison River (Western Australia), river of the same name, and the similarly named Goldfield. Economy The Mid West region has a diversified economy that varies with the geography and climate. Near the coast, annual rainfall of between allows intensive agriculture. Further inland, annual rainfall decreases to less than , and here the economy is dominated by mining of iron ore, gold, nickel and other mineral resources. Geraldton is an imp ...

Australian Systematic Botany
''Australian Systematic Botany'' is an international peer-reviewed scientific journal published by CSIRO Publishing. It is devoted to publishing original research, and sometimes review articles, on topics related to systematic botany, such as biogeography, taxonomy and evolution. The journal is broad in scope, covering all plant, algal and fungal groups, including fossils. First published in 1978 as ''Brunonia'', the journal adopted its current name in 1988. The current editor-in-chief is Daniel Murphy ( Royal Botanic Gardens Melbourne). Abstracting and indexing The journal is abstracted and indexed in BIOSIS, CAB Abstracts, Current Contents (Agriculture, Biology & Environmental Sciences), Elsevier BIOBASE, Kew Index, Science Citation Index and Scopus.

Plants Described In 1990
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
