Iris Ser. Hexagonae
Louisiana iris is a taxonomic group (''Iris'' ser. ''Hexagonae'') of five iris species native to Louisiana and surrounding regions of the southeastern United States: ''Iris fulva'', ''Iris hexagona'', ''Iris brevicaulis'', '' Iris giganticaerulea'', and ''Iris nelsonii''. Each recognized species has noticeable phenotypic and habitat differences, yet similarities between their phenotypes and habitats can be drawn. These similarities are partially a result of their similar phylogenies. Many of the species are closely related, some a result of interbreeding, as in the most recent discovery of the Abbeville Red Iris, ''Iris nelsonii''. The five Louisiana irises are often categorized as "The Reds" or "The Blues" according to their corolla color. "The Blues", species ''Iris brevicaulis'', ''Iris hexagona'', and ''Iris giganticaerulea'', typically have blue-purple corollas, with rare white forms. "The Reds", species ''Iris fulva'' and ''Iris nelsonii'', typically have red-orange corollas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Brevicaulis
''Iris brevicaulis'' is a species in the genus ''Iris (plant), Iris'', it is also in the subgenus ''Iris subg. Limniris, Limniris'' and in the series ''Louisiana iris, Hexagonae''. It is a rhizomatous perennial plant, perennial, from North America. It has bright green, glossy long leaves, a long zig-zagged stem and 3–6 flowers per stem, which are come in blue shades from violet-blue, to lavender, to purple-blue, to bright blue to blue, and pale blue. Description ''Iris brevicaulis'' is the smallest in all the ''Hexagonae series'' of Louisiana irises. Its leaves and stalks are much shorter than the other species. It is similar in form to ''Iris virginica'',Michael A. Homoy The flowers are normally never seen above the foliage,Robert H. Mohlenbroc due to the short zig-zagging flower stems and occasionally, due to the habit of the stems to lie along the floor, or it is often decumbent (meaning the branches growing horizontally but turned up at the ends).Garrett E.

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricanes
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Palmetto Island State Park
Palmetto Island State Park is a recent addition to the Louisiana State Park system. The new state park is located south of Abbeville, Louisiana in Vermilion Parish. The state of Louisiana acquired the property for the park in 1981 but did not begin construction on it with the intent of public use until 2002. State budget constraints and other concerns delayed the park's opening until October 28, 2010. The park, in size, is noted for its abundance of palmettos,(mostly Dwarf Palmetto ''Sabal minor'', commonly known as the dwarf palmetto, is a small species of palm. It is native to the deep southeastern and south-central United States and northeastern Mexico. It is naturally found in a diversity of habitats, including maritime ...) which form a dense understory in the coastal bottomland hardwood forest that predominates here. Palmetto Island State Park has a visitor's center which houses a multi-purpose room that can rented for meetings, weddings and other social events. A water p ...

Gulf Coast
The Gulf Coast of the United States, also known as the Gulf South, is the coastline along the Southern United States where they meet the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the ''Gulf States''. The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of the region are (from west to east) Brownsville, Corpus Christi, Houston, Galveston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, Gulfport, Biloxi, Mobile, Pensacola, Navarre, St. Petersburg, and Tampa. All are the centers or major cities of their respective metropolitan areas and many of which contain large ports. Geography The Gulf Coast is made of many inlets, bays, and lagoons. The coast is intersected by numerous rivers, the largest of which is the Mississippi River. Much of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swamps
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Canals
Canals or artificial waterways are waterways or river engineering, engineered channel (geography), channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport watercraft, vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and lock (water transport), locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharge (hydrology), discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
