Eleocharis
''Eleocharis'' is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (''heleios''), meaning "marsh dweller," and χάρις (''charis''), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of ''Eleocharis'' species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation (in the tropical Andes). The genus itself is relatively easy to recognize; all ''Eleocharis'' species have photosynthetic stems but no green leaves (the leaves have been reduced to sheaths surrounding the base of the stems). Many species are robust, rhizomatously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eleocharis Acicularis
''Eleocharis acicularis'' is a species of spikesedge known by the common names needle spikerush and least spikerush. It is widespread across Europe, central and southeastern Asia, North America and northeastern South America as far south as Ecuador. It is also found in Australia, where it is probably an introduced species. ''Eleocharis acicularis'' is an annual or perennial spikesedge with long, grasslike stems to about 15 centimeters (6 inches) in height, shorter in bog conditions, from a creeping rhizome. In shallow water it will form short spikes of tiny flowers amongst flat overlapping bracts. The tiny flowers are less than five millimeters in diameter and are borne at the tip of each stem in single, sharply pointed, lanceoloid spikelets up to about six millimeters long. This is a plant of marshes, vernal pools, and bogs. ''Eleocharis acicularis'' is sold commercially as an aquascape plant suitable for inclusion in artificial aquatic environments. It thrives with plenty o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleocharis Dulcis
''Eleocharis dulcis'', the Chinese water chestnut or water chestnut, is a grass-like sedge native to Asia, tropical Africa, and Oceania. It is grown in many countries for its edible corms. The water chestnut is not a nut, but an aquatic vegetable that grows in marshes, under water, in the mud. It has stem-like, tubular green leaves that grow to about . The water caltrop, which also is referred to by the same name, is unrelated and often confused with the water chestnut. The small, rounded corms have a crisp, white flesh and may be eaten raw, slightly boiled, or grilled, and often are pickled or tinned. They are a popular ingredient in Chinese dishes. In China, they are most often eaten raw, sometimes sweetened. They also may be ground into a flour form used for making water chestnut cake, which is common as part of '' dim sum'' cuisine. They are unusual among vegetables for remaining crisp even after being cooked or canned, because their cell walls are cross-linked and str ...

Eleocharis Bifida
''Eleocharis bifida'' is a species of spikesedge known by the common name glade spikerush. It is native to the Eastern United States, where it is endemic to the Interior Low Plateau and very small part of the Ridge and Valley ecoregions. This is mostly in Kentucky and Tennessee, extending into southern Indiana, northern Alabama, and northwestern Georgia. It is found only in wet areas in cedar glades, such as pools and streamsides. This narrow habitat requirement is the reason for it being considered vulnerable. ''Eleocharis bifida'' was described to science in 2001, being separated from the similar ''Eleocharis compressa ''Eleocharis'' is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (''heleios''), meaning "marsh dweller," and χάρις (''charis'' ...''.

Eleocharis Atropurpurea
''Eleocharis atropurpurea'' is a species of spikesedge known by the common name purple spikerush. This is an aquatic plant native to much of (Africa, eastern and southern Asia, Australia, Latin America). It also has a wide distribution in temperate regions of North and South America and Asia. It is present in Europe, where it may be an introduced species for the most part. ''Eleocharis atropurpurea'' can be found in wet areas from ocean shores to rice fields and irrigation ditches to inland lakes and rivers. This is an annual sedge rarely exceeding ten centimeters in height. It grows in tufts with few reddish-green leaves and many thin erect stems. Atop each stem is an oval-shaped, pointed inflorescence consisting of a spikelet under a centimeter long and containing at least ten flowers. Each tiny flower is covered by a bract which is a purplish-brown color. The fruit is a minute shiny black achene An achene (; ), also sometimes called akene and occasionally achenium or ache ...

Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...
