Angophora Hispida Dwarf Apple Gum IMG 4562 (5770965009)
''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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

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 Glossary of leaf morphology#lanceolate, lanceolate to ovate and attached to the stems by 0.6–1.5 cm (0.2–0.6 in) long Petiole (botany), petioles. The leaves in the ...

Lawrence Alexander Sidney Johnson
Lawrence Alexander Sidney Johnson (26 June 1925 – 1 August 1997) known as Lawrie Johnson, was an Australian Taxonomy (biology), taxonomic botany, 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 family (biology), families of vascular plants, 33 new genus, genera, 286 new species (including posthumous publications), and reclassified another 395 species. Of the families he described, Rhynchocalyx, 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 observed dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
