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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleocharis Dulcis
''Eleocharis dulcis'', the Chinese water chestnut or water chestnut, is a grass-like Cyperaceae, sedge native to Asia, tropical Africa, and Oceania. It is grown in many countries for its edible corms, but if eaten uncooked, the surface of the plants may transmit fasciolopsiasis. The water caltrop, which also is referred to by the same name, is unrelated and often confused with the water chestnut. Description The water chestnut is not a Nut (fruit), nut but rather an Aquatic plant, aquatic vegetable that grows in marshes, under water, or in mud. It has stem-like, tubular green leaves that grow to about . Distribution The plant is native to Asia, tropical Africa, and Oceania. Ecology In the dry season of the Northern Territory in Australia, Magpie goose, magpie geese eat the bulbs of water chestnuts, allowing them to put on fat for the wet season and ensuring they are ready for breeding. In the wet season, water chestnut leaves are used to build their floating nests. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleocharis Acuta
''Eleocharis acuta'', commonly known as common spikerush or small spikerush, is a sedge of the family Cyperaceae that is native to Australia. Description The rhizomatous perennial herb to grass-like sedge typically grows to a height of . It blooms between September and December producing brown flowers. It has fine upright cylinder-shaped deep-green foliage that tapers to a fine point. It has tufted and terete culms that are in length with a diameter of . The inflorescence is found at the tip of the spike and is composed of narrow-ovoid to narrow-cylindrical spikelets with a length of . It will later form a shiny yellow to brown coloured nut with a plano-convex to biconvex, broad-obovoid shape that is around in length with a diameter of . Taxonomy The species was first formally described by the botanist Robert Brown in 1810 as part of the work ''Prodromus Florae Novae Hollandiae''. The name of the species is often misapplied to '' Eleocharis pallens''. Distribution and habitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 A calcareous glade is a type of ecological community (ecology), community that is found in the central Eastern United States. Calcareous glade (geography), glades occur where bedrock such as limestone occurs near or at the surface, and have very ..., 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 bifida'' can be recognized by having wider stems and all floral scales bifid (2-lobed). Ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Cyperaceae
The Cyperaceae () are a family of graminoid (grass-like), monocotyledonous flowering plants known as wikt:sedge, sedges. The family (biology), family is large; botanists have species description, described some 5,500 known species in about 90 genus, generathe largest being the "true wikt:sedge, sedges" (genus ''Carex''), with over 2,000 species. Distribution Cyperaceae species are widely distributed with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges grow in almost all environments, many thrive in wetlands or in poor soils. Community (ecology), Ecological communities dominated by sedges are known as s or as sedge meadows. Classification Some species superficially resemble the closely related Juncaceae , 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 be ...

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
