Pondweed

	Pondweed Pondweed refers to many species and genera of aquatic plants and green algae: ''Potamogeton'', a diverse and worldwide genus ''Elodea'', found in North America ''Aponogeton'', in Africa, Asia and Australasia ''Groenlandia'', a genus of aquatic plants '' Stuckenia'', a genus of aquatic plants Charales Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts.

picture info	Potamogeton ''Potamogeton'' is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (''Elodea canadensis''). The genus name means "river neighbor", originating from the Greek ''potamos'' (river) and ''geiton'' (neighbor). Morphology ''Potamogeton'' species range from large (stems of 6 m or more) to very small (less than 10 cm). Height is strongly influenced by environmental conditions, particularly water depth. All species are technically perennial, but some species disintegrate in autumn to a large number of asexually produced resting buds called turions, which serve both as a means of overwintering and dispersal. Turions may be borne on the rhizome, on the stem, or on stolons from the rhizome. Most species, however, persist by perennial creeping rhizomes. In some cases the turions are the only means to differentiate species. The leav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Stuckenia ''Stuckenia'' is a genus of flowering aquatic plants. It contains approximately 30 species that grow in shallow water. Pondweed is a common name for plants in this genus. Description These herbs have rhizomes but not turions. Tubers can be absent or present. The main difference between ''Stuckenia'' and ''Potamogeton'' is that the stipule joins the leaf base. When it is pulled the sheath and stipule comes away, similar to a grass sheath and ligule.

	Groenlandia ''Groenlandia'' is a monotypic genus of aquatic plants (pondweed) of the family Potamogetonaceae. The only species in the genus is ''Groenlandia densa''. Opposite-leaved pondweed is a common name for this plant. It is native to much of Europe, western Asia and Maghreb The Maghreb (; ar, الْمَغْرِب, al-Maghrib, lit=the west), also known as the Arab Maghreb ( ar, المغرب العربي) and Northwest Africa, is the western part of North Africa and the Arab world.

picture info	Aponogeton The Aponogetonaceae (the Cape-pondweed family or aponogeton family) are a family of flowering plants in the order Alismatales. In recent decades the family has had universal recognition by taxonomists. The APG system (1998) and APG II system (2003) treat it in the order Alismatales in the clade monocots. The family consists of only one genus, ''Aponogeton'', with 56 known species (Christenhusz & Byng 2016 ) of aquatic plants, most of which have been included in a molecular phylogeny by Chen et al. (2015). The name was published in '' Supplementum Plantarum'' 32: 214 (1782) and is derived from a geographic location neighboring (''geton'') the Apono tribal district of coastal Gabon. Some species are used as ornamental plants in aquariums. Distribution They are aquatic plants, which are found in tropical to warm temperate regions of Africa, Asia and Australasia.Watson, L. & Dallwitz, M. J.

	Elodea ''Elodea'' is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog’s-bit family (Hydrocharitaceae), ''Elodea'' is native to the Americas and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water. An older name for this genus is ''Anacharis'', which serves as a common name in North America. The introduction of some species of ''Elodea'' into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem and it is now considered a noxious weed in these areas. ''Elodea canadensis'', sometimes called American or Canadian water weed or pond weed, is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking plants, like Brazilian elodea (''Egeria densa'') or hydrilla (''Hydrilla verticillata''). American water weed is an attractive aquarium plant and is a good ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
