Joy Thompson
Joy Thompson (born Joy Gardiner-Garden, 1923, died 2018) was an Australian botanist. Her main research areas were taxonomy and Myrtaceae. Life & Career Thompson's university studies occurred during the second world war and in university vacations she worked in the Land Army near Maitland. She graduated in 1946 with a B.Sc. (Agric) from the University of Sydney, and went to work at the New South Wales Herbarium (then a part of the NSW department of Agriculture). She was Honorary Secretary of the Systematic Botany Committee of ANZAAS from 1952 to 1954. In 1956 she married Max Thompson and, as a public servant, resigned from her position as was required at the time. Ten years later, after the birth of her two children, she returned to work at the Herbarium, in a part-time position. On her retirement in 1982, she became an Honorary Research Associate, and until 2009, continued to work in this role, making the 2.5 hour train journey from Mittagong once a week.

Eucalyptus Caesia
''Eucalyptus caesia'', commonly known as caesia or gungurru, is a species of mallee that is endemic to the south-west of Western Australia. It has smooth reddish brown bark at first, later shedding in curling flakes, lance-shaped, sometimes curved adult leaves, club-shaped flower buds covered with a waxy, bluish white bloom, pink stamens with yellow anthers and urn-shaped fruit.

Oxalidales Of Australia
Oxalidales is an order of flowering plants, included within the rosid subgroup of eudicots. Compound leaves are common in Oxalidales and the majority of the species in this order have five or six sepals and petals. The following families are typically placed here:Stephens, P.F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008. http://www.mobot.org/MOBOT/Research/APweb/ * Family Brunelliaceae * Family Cephalotaceae (''Cephalotus follicularis'') * Family Connaraceae * Family Cunoniaceae * Family Elaeocarpaceae * Family Huaceae * Family Oxalidaceae (wood sorrel family) The family Cephalotaceae contains a single species, a pitcher plant found in Southwest Australia. Under the Cronquist system, most of the above families were placed in the Rosales. The Oxalidaceae were placed in the Geraniales, and the Elaeocarpaceae split between the Malvales and Polygalales, in the latter case being treated as the Tremandraceae.

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Tetratheca
''Tetratheca'' is a genus of around 50 to 60 species of shrubs endemic to Australia. It is classified in the botanical family Elaeocarpaceae, now known to encompass the family Tremandraceae, which the genus originally belonged to. It occurs throughout extratropical Australia, and has been recorded in every mainland state except the Northern Territory. Origin and evolution The origin of the genus is thought to be south-western Western Australia, radiating eastward. The distribution of ''Tetratheca'' is mainly across the temperate southern part of the continent. Most species are localised endemics and are highly disjunct from each other. Very few are widespread across Australia; none occurs in the Nullarbor Plain and only seven are found on both the western and the south-eastern sides. (McPherson, 2008). The formation of the Nullarbor is thought to have created a barrier to dispersal between the east and west. It is estimated that the family Elaeocarpaceae is 120 million years ...

Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a number ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Understorey
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...
