Lawrence Alexander Sidney Johnson
Lawrence Alexander Sidney Johnson FAA, (26 June 1925 – 1 August 1997) known as Lawrie Johnson, was an Australian taxonomic botanist. He worked at the Royal Botanic Gardens, Sydney, for the whole of his professional career, as a botanist (1948–1972), Director (1972–1985) and Honorary Research Associate (1986–1997). - originally published in ''Historical Records of Australian Science'', vol.13, no.4, 2001. Alone or in collaboration with colleagues, he distinguished and described four new families of vascular plants, 33 new genera, 286 new species (including posthumous publications), and reclassified another 395 species. Of the families he described, Rhynchocalycaceae (with B. G. Briggs, 1985) is accepted by the Angiosperm Phylogeny Group (APG). Hopkinsiaceae and Lyginiaceae, (which he and B. G. Briggs proposed in 2000 be carved out of Anarthriaceae), have not been accepted by the APG. Lawrie Johnson died of cancer in 1997. He received many honours and awards, including ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill.

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Eucalypts Of Western Australia
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', ''Corymbia'', '' Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Arid National Park
Cape Arid National Park is a List of national parks of Australia, national park located in Western Australia, southeast of Perth. The park is situated east of Esperance, Western Australia, Esperance and lies on the shore of the South coast of Western Australia, south coast from the eastern end of the Recherche Archipelago. The bay at its eastern side is Israelite Bay, a locality often mentioned in Bureau of Meteorology weather reports as a geographical marker. The western end is known as Duke of Orleans Bay. Its coastline is defined by Cape Arid, a bay called Sandy Bight and, further east, Cape Pasley. History The first European to discover the area was the French Admiral Bruni D'Entrecasteaux in 1792 and he named it ''Cap Aride''; Matthew Flinders anglicized the name in 1802 and the park took its name from this feature. Pioneer Pastoral farming, graziers arrived in the area in the 1870s and the ruins of homesteads, dams and buildings as well as gravesites can be found near Pi ...

Caiguna, Western Australia
Caiguna is a small roadhouse community located on the Eyre Highway in Western Australia. It is the second stop east of Norseman on the journey east across the Nullarbor Plain. Between Balladonia and Caiguna is a stretch of the highway which is one of the longest straight stretches of road in the world. The unofficial Central Western Time (CWT) starts shortly east of Caiguna, heading eastward. History The name is an Aboriginal word possibly meaning "spear track". In 1841, Edward John Eyre's party, consisting of Eyre, a man named John Baxter and three Aboriginals including one named Wylie, travelled across the Nullarbor, leaving Fowler's Bay in South Australia. On 29 April, two of the Aboriginals killed John Baxter and disappeared into the desert, taking most of the party's supplies. Due to the terrain, Baxter could not be buried, so his remains were wrapped in a blanket and left behind, and Eyre and Wylie pressed on for another month, after which they were rescued by a Fren ...

Mallee Woodlands And Shrublands
Mallee Woodlands and Shrublands is one of 32 Major Vegetation Groups defined by the Australian Government Department of the Environment and Energy. Description " Mallee" refers to the growth habit of a group of (mainly) eucalypt species that grow to a height of , have many stems arising from a lignotuber and have a leafy canopy that shades 30–70% of the ground. The term is also applied to a vegetation association where these mallee eucalypts grow, on land that is generally flat without hills or tall trees and where the climate is semi-arid. Of the 32 Major Vegetation Groups classified under the National Vegetation Information System, "Mallee Woodlands and Shrublands" (MVG14): * are semi-arid areas dominated by mallee eucalypts; * may also have co-dominant species of '' Callitris'', '' Melaleuca'', ''Acacia'' and ''Hakea''; * have an open tree or shrub layer with more than 10% foliage cover and more than 20% crown cover, distinguishing MVG 14 from "Mallee Open Woodland" (MVG14 ...

Balladonia, Western Australia
Balladonia is a small roadhouse community located on the Eyre Highway in Western Australia. It is the first stop east of Norseman on the journey east across the Nullarbor Plain. Between Balladonia and Caiguna is a stretch of the highway which is one of the longest straight stretches of road in the world. History The name is an Aboriginal word meaning "big rock by itself". The area was settled by Europeans in 1879, and the original Balladonia homestead was built away from the present townsite. From 1897 to 1929, Balladonia was a telegraph station on the East-West Telegraph, a telegraph line running from Perth to Adelaide telegraph line, due to a previous coastal line being shorted by salt spray from the Southern Ocean. The arid climate and lack of suitable water sources restricted the town's development. In July 1979, the area gained worldwide attention when the re-entry of the Skylab space station left a trail of debris across the nearby countryside. Balladonia Statio ...

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...
