Hibbertia Dentata
''Hibbertia dentata'', commonly known as toothed guinea flower, trailing guinea flower or twining guinea flower, is an ornamental plant in the family Dilleniaceae native to the east coast of Australia. Found in woodland, it is a trailing or twining vine with leaves with several small 'teeth' on the margins and bright yellow flowers in early spring. It adapts readily to cultivation and can be grown as a pot plant. The species was first described in 1817. Description ''Hibbertia dentata'' grows as a twining vine, the stems of which can be up to in length, and trail over rocks and other shrubs. The dark green leaves are ovate, measuring long by wide., and sit on 1 cm long petioles. The apex of the leaf blade can be pointed or blunt, while the leaf margins are toothed. They can be purple-tinged and covered in fur when young and smooth upon reaching maturity. The flowers appear mainly from July to November. They arise from axillary buds or on the ends of short stems. They have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syncarpia Glomulifera
''Syncarpia glomulifera'', commonly known as the turpentine tree, or yanderra, is a tree of the family Myrtaceae native to New South Wales and Queensland in Australia, which can reach in height. It generally grows on heavier soils. The cream flowers appear in spring and are fused into compound flowerheads. Taxonomy English botanist James Edward Smith first described the turpentine as ''Metrosideros glomulifera'' in 1797, from a collection in the Sydney district. It was given its current binomial name by German botanist Franz Josef Niedenzu in 1893. Common names include turpentine, luster, red turpentine or red luster. It was formerly known as ''Syncarpia laurifolia'' Ten. Two subspecies are recognised, the widespread nominate, and subspecies ''glabra'' which is found from Bulahdelah north to Kempsey and has smooth leaf undersurfaces. Description In a suitable location, the turpentine grows into a large straight-trunked tree up to 45 or even 55 m (150–180 ft) high ...

Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

Loddiges
The Loddiges family (not uncommonly mis-spelt ''Loddige'') managed one of the most notable of the eighteenth and nineteenth century plant nurseries that traded in and introduced exotic plants, trees, shrubs, ferns, palms and orchids into European gardens. Founding and rise The founder of the nursery was Joachim Conrad Loddiges (1738–1826). He was born in Hildesheim, Lower Saxony; his father Casper Lochlies was a gardener to a nobleman in Wrisbergholzen, near Hannover. Conrad trained in The NetherlandsJenny 2008. and emigrated to Britain at the age of 19 during the Seven Years' War to take up employment as gardener for Dr J. B. Silvester in the suburban village of Hackney, north of London. It was then that the family name was anglicised. When in his forties he married, he had not accumulated sufficient savings to expand a small seed business started by fellow German émigré John Busch, which he purchased, together with the good will of Busch's clientele in 1771 and had fully ...

Colletidae
The Colletidae are a family of bees, and are often referred to collectively as plasterer bees or polyester bees, due to the method of smoothing the walls of their nest cells with secretions applied with their mouthparts; these secretions dry into a cellophane-like lining. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, pg. 133, Johns Hopkins University Press. The five subfamilies, 54 genera, and over 2000 species are all (with the known exception of but one species, '' Amphylaeus morosus'') evidently solitary, though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa) that otherwise characterizes most bees, and instead carry the pollen in their crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop. They can be found all over the world, but the most species live in South America and Australia. Over 50% of all bee spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halictidae
Halictidae is the second-largest family of bees (clade Anthophila) with nearly 4,500 species. Halictid species are an extremely diverse group that can vary greatly in appearance. These bees occur all over the world and are found on every continent except Antarctica. Usually dark-colored (frequently brown or black) and often metallic, halictids are found in various sizes, colors and patterns. Several species are all or partly green and a few are red, purple, or blue. A number of them have yellow markings, especially the males, which commonly have yellow faces, a pattern widespread among the various families of bees. The family is one of many with short tongues and is best distinguished by the arcuate (strongly curved) basal vein found on the wing. Females in this family tend to be larger than the males. They are commonly referred to as "sweat bees" (especially the smaller species), as they are often attracted to perspiration. Ecology Most halictids nest in the ground, often in ha ...

Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday 2009 in Victoria (173 people killed, 2,000 homes lost); Ash Wednesday 1983 in Victoria and South Australia (75 dead, nearly 1,900 homes); Black Frida ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
