Angophora Costata - Spreading Crown Habit
''Angophora'' is a genus of nine species of trees and shrubs in the myrtle family, Myrtaceae. Endemic to eastern Australia, they differ from other eucalypts in having juvenile and adult leaves arranged in opposite pairs, sepals reduced to projections on the edge of the floral cup, four or five overlapping, more or less round petals, and a papery or thin, woody, often strongly ribbed capsule. Species are found between the Atherton Tableland in Queensland and south through New South Wales to eastern Victoria, Australia. Description Plants in the genus ''Angophora'' are trees, occasionally shrubs, with rough bark except for '' A. costata''. The juvenile leaves differ from adult leaves in being hairy with raised oil glands. Both juvenile and adult leaves are arranged in opposite pairs, the adult leaves usually glabrous and paler on the lower surface. The flower buds are arranged in groups of three or seven. The flower has four or five small sepals, reduced to small projections on the ...

Angophora Costata
''Angophora costata'', commonly known as Sydney red gum, rusty gum or smooth-barked apple, is a species of tree that is endemic to eastern Australia. Reaching in height, the species has distinctive smooth bark that is pinkish or orange-brown when new and fades to grey with age. Its lance-shaped leaves are arranged in opposite pairs along the stems, with white or creamy white flowers appearing from October to December. The flower buds are usually arranged in groups of three, followed by ribbed, oval or bell-shaped fruit. Description ''Angophora costata'' is a tree that typically grows to a height of and forms a lignotuber. It has smooth pinkish or orange-brown bark that weathers to grey and is shed in small scales. Young plants and coppice regrowth have sessile, elliptical to egg-shaped leaves arranged in opposite pairs with a stem-clasping base, long and wide. Adult leaves are arranged in opposite pairs, glossy green but paler on the lower surface, lance-shaped or curved, ...

Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Angophora Floribunda
''Angophora floribunda'', commonly known as the rough-barked apple, is a common woodland and forest tree of the family Myrtaceae native to Eastern Australia. Reaching 30 m (100 ft) high, it is a large tree with fibrous bark and cream-white flowers that appear over the Austral summer. It grows on alluvial soils on floodplains and along watercourses. Much of the land it grew on has been cleared for agriculture. Description ''Angophora floribunda'' is a large, wide, spreading tree growing to a height of 30 m (100 ft). The trunk is often gnarled and crooked with fibrous grey bark. Like all members of the genus ''Angophora'', the dull to glossy green leaves are arranged oppositely along the stem. 5.5 to 15 cm (2.2–6 in) long and 1–5 cm (0.4–2 in) wide, they are lanceolate to ovate and attached to the stems by 0.6–1.5 cm (0.2–0.6 in) long petioles. The leaves in the western parts of the range are narrower than those in mor ...

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 ...

James Britten
James Britten (3 May 1846 – 8 October 1924) was an English botanist. Biography Born in Chelsea, London, he moved to High Wycombe in 1865 to begin a medical career. However he became increasingly interested in botany, and began writing papers on the subject. His first publication was probably that published in the '' Journal of Botany'' in 1863. He became a Catholic in 1867, and was involved at various times in social work and training choirs in Brentford, Isleworth, and Southwark. In 1869, he was appointed a junior at the Herbarium at the Royal Botanic Gardens, Kew. In 1871, he joined the Department of Botany at the British Museum and remained in this position until his retirement in 1909. In 1879, he succeeded Henry Trimen as editor of the ''Journal of Botany, British and Foreign''. He would hold the editorship for around 45 years. Botanist Norman Hall wrote of Britten: "Britten threw himself fully into the editorship, although his pungent remarks on papers submitted were ...

Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observ ...

Australian Plant Census
The Australian Plant Census (APC) provides an online interface to currently accepted, published, scientific names of the vascular flora of Australia, as one of the output interfaces of the national government Integrated Biodiversity Information System (IBIS – an Oracle Co. relational database management system). The Australian National Herbarium, Australian National Botanic Gardens, Australian Biological Resources Study and the Council of Heads of Australasian Herbaria coordinate the system. The Australian Plant Census interface provides the currently accepted scientific names, their synonyms, illegitimate, misapplied and excluded names, as well as state distribution data. Each item of output hyperlinks to other online interfaces of the information system, including the Australian Plant Name Index (APNI) and the Australian Plant Image Index (APII). The outputs of the Australian Plant Census interface provide information on all native and naturalised vascular plant taxa of Australi ...
