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 ...

Botanischer Garten München-Nymphenburg
The Botanischer Garten München-Nymphenburg is a botanical garden and arboretum in Munich, Germany. History Munich's first botanical garden, now called the " Old Botanical Garden", was established in 1809 based on designs by Friedrich Ludwig von Sckell near Karlsplatz, where its remains are still visible. It was replaced by the Botanical Garden of Munich-Nymphenburg in 1912/13 and officially opened on 10 May 1914. The garden was designed by Peter Holfelder who worked closely with Walter Kupper and Leonhard Dillis. Description The garden cultivates about 19,600 species and subspecies on an area of . Its mission is to provide a beautiful and restful environment as well as educate the public about plants and nature more broadly. Major collections include an alpine garden, an arboretum, rose collections, and a so-called "systematic garden" in which plants are arranged by taxonomic families. The garden also contains an extensive greenhouse complex (4,500 m total area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuber
Tubers are a type of enlarged structure that plants use as storage organs for nutrients, derived from stems or roots. Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and Yam (vegetable), yam. The term ''root tuber'' describes modified lateral roots, as in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning 'lump, bump, or swelling'. Some writers limit the definition of ''tuber'' to structures derived from Plant stem, stems, while others also apply the term to structures derived from 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 and leaves and the undersides produce roots. They tend to form at the s ...

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.

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 w ...

Blue Mountains (New South Wales)
The Blue Mountains ( Gundungurra/Dharug: Colomatta or Gulumada) are a mountainous region and a mountain range located in New South Wales, Australia. The region is considered to be part of the western outskirts of the Greater Sydney area. The region borders on Sydney's main metropolitan area, its foothills starting about west of centre of the state capital, close to Penrith. 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.

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular dinitrogen () is converted into ammonia (). It occurs both biologically and abiological nitrogen fixation, abiologically in chemical industry, chemical industries. Biological nitrogen fixation or ''diazotrophy'' is catalyzed by enzymes called nitrogenases. These enzyme complexes are encoded by the Nif gene, ''Nif'' genes (or ''Nif'' homologs) and contain iron, often with a second metal (usually molybdenum, but sometimes vanadium). Some nitrogen-fixing bacteria have symbiotic relationships with plants, especially legumes, mosses and aquatic ferns such as ''Azolla''. Looser non-symbiotic relationships between diazotrophs and plants are often referred to as associative, as seen in nitrogen fixation on rice roots. Nitrogen fixation occurs between some termites and fungus, fungi. It occurs naturally in the air by means of NOx, NOx production by lightning. Fixed nitrogen is essential to life on Earth.
