Amyema Congener
''Amyema congener'', commonly known as the variable mistletoe, is a species of flowering plant, an epiphytic hemiparasitic plant of the family Loranthaceae from eastern Australia. It is found on members of the genera ''Allocasuarina'', ''Acacia'' and some exotic species. Franz Sieber first described this species as ''Loranthus congener'' in 1829, before Philippe Édouard Léon Van Tieghem gave it its current binomial name in 1894. It grows as shrubby plant, with either an erect or pendant (drooping) habit, from a tree branch or trunk. It is attached to the host tree by a globular woody base. The stems and foliage are smooth. The thick leathery leaves are spear-shaped (lanceolate) to oval or obovate and measure in length and across. Flowers can be seen at any time of year. The diameter round fruit ripen over the summer (December to February), and the single seed within is contained in a sticky membrane. The principal host plant of the variable mistletoe is the black sheoak (' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Melaleuca Linariifolia
''Melaleuca linariifolia'' is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. It is commonly known as snow-in-summer, narrow-leaved paperbark, flax-leaved paperbark and in the language of the Gadigal people as ''budjur''. A hardy plant, it flowers prolifically in late spring or summer, making it a popular garden shrub or small tree in temperate places. ''Melaleuca trichostachya'' is a similar species but its leaves are arranged differently and the fruits have projecting valves. Description ''Melaleuca linariifolia'' is a small tree growing to a height of with distinctive and attractive white or creamy white, papery bark and a dense canopy. Its leaves are arranged in alternating pairs (decussate), glabrous except when very young, long, wide, linear to lance-shaped and with a distinct mid-vein.

Flora Of Queensland
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xylem
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word ''xylem'' is derived from the Ancient Greek word (''xylon''), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. The term was introduced by Carl Nägeli in 1858. Structure The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called ''vessels''. Xylem also contains two other type of cells: parenchyma and fibers. Xylem can be found: * in vascular bundles, present in non-woody plants and non-woody parts of woody plants * in secondary xylem, laid down by a meristem called the vascular cambium in woody plants * as part of a stelar arrangement n ...

Aspidiotus Aurantii
''Aspidiotus'' is a genus of armoured scale insects. It includes several agricultural and horticultural pests. ''A. destructor'' was originally blamed for a massive die-off of coconut trees in the Philippines which began about 2009. It has been involved previously in die-offs in Indonesia. In July 2014, following a detailed morphological review, scientists announced that instead ''A. rigidus'', was to blame. ''A. rigidus'' has few natural predators in the Philippines which leads to the surging infestation.

Ceroplastes Rubens
''Ceroplastes rubens'', known generally as the red wax scale or pink wax scale, is a species of soft scale insect in the family Coccidae. It is native to Australia but has been introduced to other countries, including New Caledonia, Japan, China, Poland and the United States. Description Adult females of ''C. rubens'' are covered in a hard, pink/pale red covering of wax. With this covering, they are about 3-4 mm long, globular and smooth in shape, with a depression on the top and two lobes on each side. They have stigmatic setae of two types (bullet-like and hemispherical), and there are two pair of setae between the antennae. Eggs of this species are brick red. These hatch into crawlers, the first nymphal instar, which have three pairs of legs, two eye spots and a pair of antennae. Later nymphal instars are covered in wax like the adult female, though their wax is initially white. Life cycle Red wax scales begin their lives as eggs, which are held in a cavity under th ...

Mistletoebird
The mistletoebird (''Dicaeum hirundinaceum''), also known as the mistletoe flowerpecker, is a species of flowerpecker native to most of Australia (though absent from Tasmania and the driest desert areas) and also to the eastern Maluku Islands of Indonesia in the Arafura Sea between Australia and New Guinea. The mistletoebird eats mainly the berries of the parasitic mistletoe and is a vector for the spread of the mistletoe's seeds through its digestive system.del Hoyo, J. et al., eds. (2008). ''Handbook of the Birds of the World'' 13: 388. . Taxonomy and evolution The mistletoebird is one of 44 species of the flowerpecker family Dicaeidae. The flowerpeckers are considered to be nearest in avian evolutionary relationship to the sunbird family Nectariniidae. Both the flowerpeckers and sunbirds are thought to be early offshoots of the early passeroid radiation that occurred 20-30 million years ago. The sunbirds are found mainly in Africa and Asia and the flowerpeckers throughout Asi ... [...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.

Eucalyptus Obtusifolia
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grown ...

Nerium Oleander
''Nerium oleander'' ( ), most commonly known as oleander or nerium, is a shrub or small tree cultivated worldwide in temperate and subtropical areas as an ornamental and landscaping plant. It is the only species currently classified in the genus ''Nerium'', belonging to subfamily Apocynoideae of the dogbane family Apocynaceae. It is so widely cultivated that no precise region of origin has been identified, though it is usually associated with the Mediterranean Basin. Nerium grows to tall. It is most commonly grown in its natural shrub form, but can be trained into a small tree with a single trunk. It is tolerant to both drought and inundation, but not to prolonged frost. White, pink or red five-lobed flowers grow in clusters year-round, peaking during the summer. The fruit is a long narrow pair of follicles, which splits open at maturity to release numerous downy seeds. Nerium contains several toxic compounds, and it has historically been considered a poisonous plant. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
