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 ...

Mount Lofty Ranges
The Mount Lofty Ranges are a range of mountains in the Australian state of South Australia which for a small part of its length borders the east of Adelaide. The part of the range in the vicinity of Adelaide is called the Adelaide Hills and defines the eastern border of the Adelaide Plains. Location and description The Mount Lofty Ranges stretch from the southernmost point of the Fleurieu Peninsula at Cape Jervis northwards for over before petering out north of Peterborough. In the vicinity of Adelaide, they separate the Adelaide Plains from the extensive plains that surround the Murray River and stretch eastwards to Victoria. The Heysen Trail traverses almost the entire length of the ranges, crossing westwards to the Flinders Ranges near Hallett. The mountains have a Mediterranean climate with moderate rainfall brought by south-westerly winds, hot summers and cool winters. The southern ranges are wetter (with of rain per year) than the northern ranges (). Southern rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious Plants
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagales Of Australia
The Fagales are an order of flowering plants, including some of the best-known trees. The order name is derived from genus ''Fagus'', beeches. They belong among the rosid group of dicotyledons. The families and genera currently included are as follows: *Betulaceae – birch family (''Alnus'', ''Betula'', ''Carpinus'', ''Corylus'', ''Ostrya'', ''Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', ''Ceuthostoma'', ''Gymnostoma'') *Fagaceae – beech family ('' Castanea'', ''Castanopsis'', ''Chrysolepis'', ''Colombobalanus'', ''Fagus'', '' Lithocarpus'', ''Notholithocarpus'', ''Quercus'') *Juglandaceae – walnut family (''Alfaroa'', ''Carya'', ''Cyclocarya'', ''Engelhardia'', ''Juglans'', ''Oreomunnea'', ''Platycarya'', ''Pterocarya'', ''Rhoiptelea'') *Myricaceae – bayberry family (''Canacomyrica'', '' Comptonia'', ''Myrica'') *Nothofagaceae – southern beech family (''Nothofagus'') *Ticodendraceae – ticodendron family ('' Ticodendron'') The ...

Flora Of South Australia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allocasuarina
''Allocasuarina'' is a genus of trees in the flowering plant family Casuarinaceae. They are endemic to Australia, occurring primarily in the south. Like the closely related genus ''Casuarina'', they are commonly called sheoaks or she-oaks. Wilson and Johnson distinguish the two very closely related genera, ''Casuarina'' and ''Allocasuarina'' on the basis of: *''Casuarina'': the mature samaras being grey or yellow-brown, and dull; cone bracteoles thinly woody, prominent, extending well beyond cone body, with no dorsal protuberance; *''Allocasuarina'': the mature samaras being red-brown to black, and shiny; cone bracteoles thickly woody and convex, mostly extending only slightly beyond cone body, and usually with a separate angular, divided or spiny dorsal protuberance. Description They are trees or shrubs that are notable for their long, segmented branchlets that function as leaves. Formally termed cladodes, these branchlets somewhat resemble pine needles, although sheoaks ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Desert National Park
The Little Desert National Park is a national park in the Wimmera Mallee region of Victoria, Australia. The national park is situated near Dimboola, approximately west of Melbourne and extends from the Wimmera River in the east to the South Australian border in the west near . While the region is surrounded by agricultural land, the area of the Little Desert itself "consists mainly of deep sandy soils with very low fertility, interspersed with small pockets of clay soils. There are occasional rocky, sandstone outcrops and buckshot rises. Average yearly rainfall varies remarkably from the east to the west." The Little Desert "remains relatively undisturbed by human activity, even though in the earlier years of European settlement it experienced some industry in the way of grazing and woodcutting." Now the desert is a National Park, and is "broken up into three blocks": Western Block, Central Block and Eastern Block; demarcated by two north-south roads, the Nhill-Harrow road an ...

Wyperfeld National Park
The Wyperfeld National Park is the third largest national park in Victoria, Australia, located in the Mallee district, approximately northwest of Melbourne, The national park was declared in 1921 and expanded significantly to protect of mallee, woodland, and heathland. For management purposes, the Wyperfeld National Park is managed with the Hattah-Kulkyne National Park, Murray-Sunset National Park, Lake Albacutya Park and Murray-Kulkyne Park as part of the Victorian Mallee Parks. History Like most of north-western Victoria, Wyperfeld was a shallow sea from about 25 million years ago until fairly recent times. The current landforms took shape as the sea gradually retreated, leaving a vast expanse of sandy sediment which, as it dried, was formed into sand dunes during the period 40,000 to 15,000 years ago. Before European settlement, the network of ephemeral lakes filled and emptied, on average, about every 20 years, typically remaining dry for about half that period at a time. ...

Keith, South Australia
Keith is a town and a locality in the Australian state of South Australia located in the state's south-east about from the state capital of Adelaide at the junction of the Dukes Highway and the Riddoch Highway. It is sometimes referred to as the 'lucerne capital of Australia' due to the high number of lucerne growers in the region. The 2016 Australian census which was conducted in August 2016 reports that Keith had a population of 1355 people of which 1076 lived in the town centre. History A large granite outcrop outside the town called Mount Monster was a basis for the area's name until it was surveyed in 1884 and officially proclaimed Keith in 1889. It is believed that the town is named after the home town of the Governor of South Australia at the time, Lord Kintore. His home in Aberdeenshire in Scotland was called Keith Hall and he was also known as Earl of Kintore. The Post Office opened around 1874 as Mount Monster and was renamed Keith in 1904.

Pinnaroo, South Australia
Pinnaroo is a town in the Murray Mallee region of South Australia, near the border with Victoria, 243 km east of Adelaide. Pinnaroo is on the north side of the Mallee Highway, and on the railway line between Tailem Bend and Ouyen. The roadhouse on the highway at Pinnaroo is the first "food and leg-stretch" stop on the bus route from Adelaide to Sydney. At the 2016 census, the locality of Pinnaroo had a population of 712 of which 547 lived in and around its town centre. History The town's name is derived from a word for "big man" in a local Aboriginal language. The railway arrived in the area in 1906. There had not been any significant development in the area before that, as the remoteness and difficulty of getting supplies in and produce out had made it uneconomic to farm before that. Economy The railway is not currently available for transport between the states, as the line from Tailem Bend was converted to standard gauge and more recently mothballed forcing grain ...
