Xylomelum Pyriforme
''Xylomelum pyriforme'', commonly known as the woody pear, is a species of plant in the family Proteaceae native to eastern Australia. It grows as a large shrub or small tree to five metres high. Taxonomy ''Xylomelum pyriforme'' was first documented at Botany Bay in 1770 by Joseph Banks and Daniel Solander, who gave it the (unpublished) binomial name ''Leucadendroides pyrifera'' in ''Banks' Florilegium''. It was first formally described as ''Banksia pyriformis'' by German botanist Joseph Gaertner in 1788 in ''De Fructibus et Seminibus Plantarum''. It was given its current name in 1809 by the gardener Joseph Knight in his ''On the cultivation of the plants belonging to the natural order of Proteeae''. The species name "pear-shaped" is derived from the Latin words ''pyrus'' "pear" and ''forma'' "shape". Description ''Xylomelum pyriforme'' grows as a large shrub or small tree, usually reaching high, although trees to have been recorded in the Howes Valley northwest of Sydney. T ...

Muogamarra Nature Reserve
The Muogamarra Nature Reserve () is a protected nature reserve that is located in the Sydney region of New South Wales, in eastern Australia. The reserve is situated in the northern edge of Sydney and lies between the suburb of to the south, and the Hawkesbury River to the north. Features The vegetation is mainly dry sclerophyll forest and shrubs on rocky areas, as well as mangroves along the river. The reserve is closed to the public for most of the year, and opens for six weekends each year in spring, when there are prolific displays of wildflowers. At other times of the year it is available to groups such as the scouts or to schools for education or special events. During the weekends that the reserve is open to the public, volunteers provide guided walks around some of the trails. Access to the Muogamarra Nature Reserve is via the Pacific Highway (not the M1 Pacific Motorway), approximately north of Cowan, near the Pie in the Sky cafe. A small gravel road with a ga ...

Corymbia Eximia
''Corymbia eximia'', commonly known as the yellow bloodwood, is a bloodwood native to New South Wales. It occurs around the Sydney Basin often in high rainfall areas on shallow sandstone soils on plateaux or escarpments, in fire prone areas. Growing as a gnarled tree to , it is recognisable by its distinctive yellow-brown tessellated bark. The greyish green leaves are thick and veiny, and lanceolate spear- or sickle-shaped. The cream flowerheads grow in panicles in groups of seven and appear in spring. Known for many years as ''Eucalyptus eximia'', the yellow bloodwood was transferred into the new genus ''Corymbia'' in 1995 when it was erected by Ken Hill and Lawrie Johnson. It is still seen under the earlier name in some works. Description The yellow bloodwood grows as an attractive gnarled tree, up to tall. It can have a multistemmed stunted habit when growing on an exposed site. The distinctive bark is a yellowish fawn colour, and flaky, rough in consistency with a somewha ...

Xylomelum
''Xylomelum'' is a genus of six species of flowering plants, often commonly known as woody pears, in the family Proteaceae and are endemic to Australia. Plants in this genus are tall shrubs or small trees with leaves arranged in opposite pairs, relatively small flowers arranged in spike-like groups, and the fruit a woody, more or less pear-shaped follicle. Description Plants in the genus ''Xylomelum'' are shrubs or trees that typically grow to a height of and have simple, leathery leaves arranged in opposite pairs. Juvenile leaves have coarse, sometimes prickly teeth on the edges. The flowers are arranged in dense, spike-like racemes or panicles, the flowers in pairs with a bract at the base. Each flower has four similar tepals that roll back as the flower develops revealing four stamens. The fruit is a woody, more or less pear-shaped follicle attached at the larger end, that eventually splits into two halves and releases two winged seeds. Taxonomy The genus ''Xylomelum'' was ...

Edward Minchen
Edward William Minchen/Minchin (25 June 1852 – 1913) was an Australian botanical artist. Minchen was born in Middle Swan, Perth, Western Australia, the son of James Minchen and Elizabeth Fisher, and had a fairly checkered career pursuing jobs at sea, trades, an attempt at the stage and the National Art Gallery. He ended up working as a lithographer in New South Wales for the Lands Department, the Survey Office and the Government Printer. He often collaborated with Henry Baron (1863-?), a lithographic artist who joined the Government Printer in 1891. Family Elizabeth Fisher (*1834), daughter of William Fisher (1803-1878) and Elizabeth Witt Wittle (1808-), at 17, married James Minchin (24 June 1821, Petersfield, Hampshire - 26 May 1901, Mooroopna, Victoria), son of James Minchin (1799-1837) and Elizabeth Tewlett, on 24 August 1851 at Middle Swan. James, a carpenter, was the brother of Hester/Esther Minchin (20 August 1828 Petersfield, Hampshire - 11 September 1900 South Austral ...

Stock (firearms)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damping Off
Damping off (or damping-off) is a horticultural disease or condition, caused by several different pathogens that kill or weaken seeds or seedlings before or after they germinate. It is most prevalent in wet and cool conditions. Symptoms There are various symptoms associated with damping off; these reflect the variety of different pathogenic organisms which can cause the condition. However, all symptoms result in the death of at least some seedlings in any given population.Buczacki, S., and Harris, K., ''Pests, Diseases and Disorders of Garden Plants'', Collins, 1998, pp. 481–2. Groups of seedlings may die in roughly circular patches, the seedlings sometimes having stem lesions at ground level. Stems of seedlings may also become thin and tough ("wire-stem") resulting in reduced seedling vigor. Leaf spotting sometimes accompanies other symptoms, as does a grey mold growth on stems and leaves. Roots sometimes rot completely or back to just discolored stumps. Causal agents A numbe ...

Lignotuber
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr. Plants possessing lignotubers include many species in Australia: ''Eucalyptus marginata'' (Jarrah), ''Eucalyptus brevifolia'' (snappy gum) and ''Eucalyptus ficifolia'' (scarlet gum) all of which can have lignotubers wide and deep, as well as most mallees (where it is also known as a mallee root) and many ''Banksia ...

Eucalyptus Sclerophylla
''Eucalyptus sclerophylla'', known as the scribbly gum, is a tree native to eastern Australia. Very similar to the related Scribbly Gum (''E. haemastoma''), a better known tree. The best way of distinguishing the species is the smaller hemispherical to pear shaped gumnuts of ''Eucalyptus sclerophylla'', being 0.6 cm by 0.6 cm in size. Flower buds are also smaller. ''sclerophylla'' literally means ''hard leaf''. Both species have hard leaves, but Eucalyptus sclerophylla's leaves are particularly hard edged. Occurring on the poorer sandstone soils in mid to high rainfall areas. Around Sydney it often occurs on the higher ridges, where the soil is drier and less fertile. It ranges north from Jervis Bay, to near the Watagan district near Newcastle Newcastle usually refers to: *Newcastle upon Tyne, a city and metropolitan borough in Tyne and Wear, England *Newcastle-under-Lyme, a town in Staffordshire, England *Newcastle, New South Wales, a metropolitan area in Australia, ...
