Macrozamia Spiralis
''Macrozamia spiralis'' is a species of cycad in the family Zamiaceae. It is endemic to New South Wales in eastern Australia, where it is found in sclerophyll forest on low-nutrient soils. Plants generally lack a trunk and have 2–12 leaves that range up to 100 cm (40 in) in length. Taxonomy Richard Anthony Salisbury described this species as ''Zamia spiralis'' in 1796, from a collection made somewhere in the vicinity of Port Jackson (Sydney); however, no type specimen is extant. Dutch botanist Friedrich Anton Wilhelm Miquel gave it its current name in 1842. Meanwhile, Joseph Dalton Hooker described ''M. corallipes'' from a plate in 1872. For many years, the name ''M. spiralis'' was applied to the large common cycad from the Sydney region, while its smaller relative was known as ''M. corallipes''. In 1959, New South Wales Herbarium botanist Lawrie Johnson examined the species descriptions and determined that Salisbury's original description was in fact of the smaller s ...

Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typical stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Putty, New South Wales
Putty is a village in New South Wales, Australia in Singleton Shire. It is north west of Sydney on the Putty Road between Windsor and Singleton. Geography The village lies in a wide valley. The knee-deep Putty Creek, or the Tupa, rises in north at the foot of Mt Kindarun, and runs the length of the valley before joining with the Wollemi Creek which then feeds into the Colo River. Adjoining the Putty Road (State Route 69) at a distance of from Singleton and from Windsor, Putty Valley Road services the northern stretch of the valley, while the recently relocated Box Gap Road services the south western end. Land holdings in the area extend to the boundaries of the Wollemi National Park in the west and south, the Putty State Forest in the north and the Yengo National Park in the East. Commerce While the number of large land holdings in Putty are diminishing to make way for smaller hobby farms, livestock production (primarily beef cattle) continues on a small scale. A saw mill, ...

Maroota, New South Wales
Maroota is a suburb to the north-west of Sydney, New South Wales, Australia. Maroota is located 49 kilometres north-west of the Sydney central business district, in the Local government in Australia, local government areas of The Hills Shire and Hornsby Shire. Maroota is located at a high point, about 200 m above sea-level, on the ridge-following Great Northern Road (now renamed Old Northern Road). This was the main early road, constructed by convict gangs, from Sydney north to Singleton in the Hunter Valley. It is the last northwest suburb of Sydney. Maroota is situated on, and owes its nature to, Chris Nesci (the Maroota Sand) which geologists think may be the oldest known remnant of the largest waterway in the Sydney region, the Nepean-Hawkesbury system. History The first attempt to settle Maroota, as a soldier-settlement, failed totally. Some of the soldiers leaving the Army during an across-the-Empire downsizing in the wake of the Napoleonic wars bought land (sight-unse ...

Wallacia, New South Wales
Wallacia is a suburb of Sydney, in the state of New South Wales, Australia. Formerly a rural village it is west of the Sydney GPO (General Post Office), in the local government areas of the City of Penrith, City of Liverpool and Wollondilly Shire. It is part of the Greater Western Sydney region. History Originally the region was called Riverview, but later became known locally as Wallace after Robert Wallace who grazed cattle on the that he rented from Sir Charles Nicholson 1st Bt. of Luddenham. His house became the unofficial Post Office from November 1885, situated at the rear of what is now the Wallacia Store and Newsagents. By 1897, a school built in the area was known as Wallace School. When the Post Office became official in November 1905, the G.P.O. named the area Boondah, as the name Wallace was already in use elsewhere in New South Wales. However, local people objected and to retain the link with Wallace, they suggested that the area be called Wallacia. This name was ...

Blue Mountains (New South Wales)
The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about west of centre of the state capital, close to Penrith on the outskirts of Greater Sydney region. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. As defined in 1970, the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin. The ''Blue Mountains Range'' comprises a range of mountains, plateau escarpments extending off the Great Dividing Range about northwest of Wolgan Gap in a generally southeasterly direction for about , terminating at .

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular nitrogen (), with a strong triple covalent bond, in the air is converted into ammonia () or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or ''diazotrophy'' is an important microbials mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif). Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen-containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids. As part of the nitrogen cycle, it is essential for agriculture and the manufacture of fertilizer. It is also, indirectly, relevant to the manufacture of all nitrogen chemical c ...
