Amyema Plicatula
''Amyema plicatula'' is a species of hemi-parasitic shrub found in the Bismarck Archipelago, New Guinea, New South Wales and Queensland. Description It is an aeria,l stem-parasitic shrub, with short epicortical runners. The leaves, which are usually opposite, are elliptic to obovate, and about 5.5-11 cm by 3-8 cm, with no obvious venation. They sometimes occur in whorls of 3 to 4, on short stalks which are 0.4-0.8 cm long. The flowers occur in umbels. The primary stalk of the inflorescence is about 12-20 mm long, with the stalks in the umbels being about 5-10 mm long. The flowers in their diads or triads are stalkless. The calyx lobes are inconspicuous or non-existent. The corolla lobes are red, and about 20-23 mm by 8-10 mm. The anthers are about 3 mm long on anther filaments which are about 8 mm long.

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 reco ...

Loranthus
''Loranthus'' is a genus of parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers. Other treatments restrict the genus to a few species. The systematic situation of ''Loranthus'' is not entirely clear. The generic name in botanical Latin means strap-flower, in reference to the shape of the petals. Taxonomy The taxonomic history of the generic name ''Loranthus'' is complicated. In 1753, Carl Linnaeus used the name ''Loranthus'' for a genus of one species, ''Loranthus americanus'', which was thus the type species. He later added other species, including ''Loranthus scurrula'' in 1762, a species he had previously placed in a separate genus, ''Scurrula'', and ''Loranthus europaeus'' in 1763, a name first used by Jacquin in 1762. However, ''Loranthus americanus'' has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Queensland
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. 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 Thu ...

Parasitic Plants
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or '' Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Government
The Australian Government, also known as the Commonwealth Government, is the national government of Australia, a federal parliamentary constitutional monarchy. Like other Westminster-style systems of government, the Australian Government is made up of three branches: the executive (the prime minister, the ministers, and government departments), the legislative (the Parliament of Australia), and the judicial. The legislative branch, the federal Parliament, is made up of two chambers: the House of Representatives (lower house) and Senate (upper house). The House of Representatives has 151 members, each representing an individual electoral district of about 165,000 people. The Senate has 76 members: twelve from each of the six states and two each from Australia's internal territories, the Australian Capital Territory and Northern Territory. The Australian monarch, currently King Charles III, is represented by the governor-general. The Australian Government in its exec ...

Australian Tropical Rainforest Plants
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which are treated in a separate key called Australian Tropical Rainforest Orchids (see External links section). A key for ferns is under development. RFK is a project initiated by the Australian botanist Bernie Hyland. History The information system had its beginnings when Hyland started working for the Queensland Department of Forestry in the 1960s. It was during this time that he was tasked with the creation of an identification system for rainforest trees, but given no direction as to its format. Having little belief in single-access keys, he began work on creating a multi-access ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus ('' Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysoxylum Fraseranum
''Dysoxylum'' is a flowering plant genus of trees and shrubs from the mahogany family, Meliaceae. Botanical science has recorded about eighty species in this genus, growing widely across the regions of Malesia, the western Pacific ocean, Australia and south & southeastern Asia; centred on the tropics between the Pacific and Indian Oceans. They grow naturally in New Guinea, eastern and northern Australia, New Caledonia, Fiji, SE Asia, southern China, the Indian subcontinent, the Philippines, Taiwan, and in the western Pacific Ocean their most easterly occurrences, in the Caroline Islands, New Zealand and Niue. The etymology of its name ''Dysoxylum'' derives from the Greek word ‘''Dys''’ meaning "bad" referring to "ill-smelling" and ‘''Xylon''’ meaning "wood". Distribution New Guinea has records of twenty eight species growing naturally, sixteen of them endemic. New Caledonia has recorded nine, eight of them endemic. Fiji has recorded nine, seven of them endemic. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amyema
''Amyema'' is a genus of semi- parasitic shrubs (mistletoes) which occur in Malesia and Australia. Etymology ''Amyema'' derives from the Greek: ''a'' (negative), and ''myeo'' (I initiate), referring to the genus being previously unrecognised. Description Hamilton & Barlow describe the haustorial structures of most Australian ''Amyemas'' as being ball-like, with some exceptions. Species There are approximately 90 species including the following: * '' Amyema arthrocaulis'' Barlow * '' Amyema artensis'' (Mont.) Dan. (indigenous to Upolu and Savai'i, known as ''tapuna''.) * '' Amyema benthamii'' (Blakely) Danser * '' Amyema betchei'' (Blakely) Danser * '' Amyema bifurcata'' (Benth.) Tiegh. * '' Amyema biniflora'' Barlow * '' Amyema brassii'' Barlow * '' Amyema brevipes'' (Tiegh.) Danser * '' Amyema cambagei'' (Blakely) Danser * ''Amyema congener'' (Sieber ex Schult. & Schult.f.)

Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are '' Nuytsia floribunda'' (the Western Australian Christmas tree), '' Atkinsonia ligustrina'' (from the Blue Mountains of Australia), and ''Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while ''Tristerix aphyllus'' is almost holoparasitic. For a more complete description of the Australian Loranthaceae, seFlora of Australia online, for the Malesian Loranthaceae seFlora of Malesia Originally, Loranthaceae contained all mistletoe species, but the mistletoes of Europe and North America ('' Viscum'', ''Arceuthobium'', and '' Phoradendron'') belong to the family Santalaceae. The APG II system 2003 assigns the family to the order Santalales in the clade core eudicots. P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurt Krause
Kurt Krause (April 20, 1883 in Potsdam – November 19, 1963 in Berlin) was a German botanist who wrote 33 articles and five books on the flora and vegetation of Turkey about 9300 species of vascular plant were known to grow in Turkey. By comparison, Europe as a whole contains only about 24% more species (about 11500), despite having thirteen times the area. The most important reasons for the high plant biodi .... Between 1933 and 1939, he was a professor of botany at the Ankara Agricultural Institute. Krause retired in 1950.
