Juncaginaceae
Juncaginaceae is a Family (biology), family of flowering plants, recognized by most taxonomists for the past few decades. It is also known as the ''arrowgrass'' family. It includes 3 genera with a total of 34 known species (Christenhusz & Byng 2016 ). The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes such a family and places it in the order Alismatales, in the clade monocots. The species are found in cold or temperate regions in both the Northern Hemisphere, Northern and Southern Hemisphere. However APG IV (2016) removed the genus ''Maundia'' due to its non-exclusive relationship, and elevated it to the monogeneric family Maundiaceae. Description Juncaginaceae are marsh or aquatic herbs with linear, sheathing basal leaves. The flowers are small and green in erect spikes or racemes. The flower parts come in threes, but the carpels are either 3 or 6, joined to a superior ovary. The fruit is a capsule. Example arrowgrasses ''Triglochin'' includ ...

Alismatales Families
The Alismatales (alismatids) are an order of flowering plants including about 4,500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Description The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetroncium
''Tetroncium'' is a genus of plants in the Juncaginaceae described as a genus in 1808. It contains only one known species, ''Tetroncium magellanicum'', known from a few sub-Antarctic islands: Tierra Del Fuego (Chile and Argentina), Falkland Islands, and Gough Island. The plant got the name magellanicum because the original description was describing the sample found near the Strait of Magellan The Strait of Magellan (), also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and Tierra del Fuego to the south. The strait is considered the most important natural pass ....

Triglochin
''Triglochin'' is a plant genus in the family Juncaginaceae described by Carl Linnaeus in 1753. It is very nearly cosmopolitan in distribution, with species on every continent except Antarctica. North America has four accepted species, two of which can also be found in Europe: ''Triglochin palustris'' (marsh arrowgrass) and ''Triglochin maritima'' (sea arrowgrass). Australia has many more. The most widely used common name for the genus is arrowgrass, although these plants are not really grasses. Many of the common names for species make use of the term "arrowgrass", although there are exceptions: '' T. procera'', for example, is commonly known as water ribbons. Arrowgrasses are used as food plants by the larvae of some Lepidoptera species including the grey chi moth. Description This genus contains marsh herbs with flat or cylindrical leaves. The inflorescences are spikes or racemes. The flowers have two bracts. Each flower has three or six herbaceous and deciduous peria ...

Lilaea (plant)
''Lilaea'' is a monotypic genus of aquatic plants containing the single species ''Lilaea scilloides'', which is known by the common names flowering quillwort, awl-leaf lilaea, and simply lilaea. The taxonomy of this plant has been in debate, with some authors assigning it to a family of its own named Lilaeaceae, and others keeping it in the small arrowgrass family, Juncaginaceae. It is native throughout the Americas and it can be found elsewhere as an introduced species, particularly in Australia. This is an annual herb growing in or just next to water in several types of shallow aquatic habitat, including vernal pools, mudflats, and ditches. The plant takes the form of a tuft of basal leaves around a very short stem. Each onionlike leaf is very narrow, long and pointed, reaching 25 to 40 centimeters long. It is wrapped in a translucent sheath at the base. The inflorescences include clusters of staminate and bisexual flowers at the tip of a narrow stalk as well as pistillate ...

Triglochin Maritima
''Triglochin maritima'' is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in brackish marshes, freshwater marshes, wet sandy beaches, fens, damp grassland and bogs. It has a circumboreal distribution, occurring throughout the northern Northern Hemisphere. In the British Isles it is common on the coast, but very rare inland. Description It is similar to marsh arrowgrass (''Triglochin palustris'') but has the following differences: it has stolons, is stouter. The leaves are fleshy and not furrowed above. It is not very aromatic. The raceme are more dense and like sea plantain. The flowers are fleshier.C. Dwight Marsh, A. B. Clawson, and G. C. Roe Jr (1929).

Triglochin Palustris
''Triglochin palustris'' or marsh arrowgrass is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in damp grassland usually on calcareous soils, fens and meadows. The species epithet ''palustris'' is Latin for "of the marsh" and indicates its common habitat.Archibald William Smith It has a circumboreal distribution, occurring throughout northern parts of the Northern Hemisphere. It can be found locally in the British Isles especially the north. Description It is a slender perennial herb 15 to 40 cm tall. It has no stolons, and emits a pleasant aromatic smell when bruised. The leaves are linear, 10 to 20 cm long, rounded on the lower side, deeply grooved on the other. It has many 3 petaled flowers arranged in a long spike, with purple edged perianth segments, 2 mm long. It flowers from June until August. The fruits are club shaped, 10 mm long and 2 mm wide.

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triglochin Trichophora
''Triglochin trichophora'' is an annual herb native to Australia. Description It grows as an annual herb from 5 to 15 centimetres in height. Taxonomy This species was published in 1846 by Christian Gottfried Daniel Nees von Esenbeck. It has had an uneventful taxonomic history. Distribution and habitat It grows in swamps and coastal areas of Western Australia, South Australia and Victoria Victoria most commonly refers to: * Victoria (Australia), a state of the Commonwealth of Australia * Victoria, British Columbia, provincial capital of British Columbia, Canada * Victoria (mythology), Roman goddess of Victory * Victoria, Seychelle ....

APG IV
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
