Lemna obscura is a species of plant in the subfamily Lemnoideae of the family Araceae. It ranges from the United States south to Colombia and Ecuador.
Gandia is a city and municipality in the Valencian Community, eastern Spain on the Mediterranean. Gandia is located on the Costa del Azahar, 65 kilometres (40 mi) south of Valencia and 110 km (68 mi) north of Alicante. Vehicles can access the city through road N-332.
Lemna is a genus of free-floating aquatic plants referred to by the common name "duckweed". They are morphologically divergent members of the arum family Araceae. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Currently, 14 species of Lemna are recognised.
Spirodela is a genus of aquatic plants, one of several genera containing plants commonly called duckweed. Spirodela species are members of the Araceae under the APG II system. They were formerly members of the Lemnaceae.
Biolex Therapeutics was a biotechnology firm in the Research Triangle of North Carolina which was founded in 1997 and raised $190 million from investors. It filed for Chapter 7 bankruptcy on July 5, 2012.
The Ouémé River, also known as the Weme River, is a river in Benin. It rises in the Atakora Mountains, and is about 510 kilometres (320 mi) long. It flows past the towns of Carnotville and Ouémé to a large delta on the Gulf of Guinea near the seaport city of Cotonou. The largest tributaries are the Okpara River and the Alpouro River.
Bookham Commons are two commons, situated just to the north of the villages of Great Bookham and Little Bookham, in Surrey, England, 154.7 hectares in extent; the individual parts are named Great Bookham Common and Little Bookham Common. A group of dwellings known as the Isle of Wight is situated within the site, and a track, Common Road, leads to it from the northwest. Little Bookham Common lies south and west of this track, whereas Great Bookham Common lies to the east.

Spirodela punctata is a species of duckweed (Lemnoideae). The species is morphologically intermediate between Lemna and other species of Spirodela. In 1999 D.H. Les and D.J. Crawford proposed segregating the species to a new genus Landoltia containing just the species L. punctata, on the basis of biochemical and DNA studies.
Lemna minor, the common duckweed or lesser duckweed, is a species of aquatic freshwater plant in the subfamily Lemnoideae of the arum family Araceae. L. minor is used as animal fodder, bioremediator, for wastewater nutrient recovery, and other applications.
Lemna trisulca L. is a species of aquatic plants in the arum family Araceae. It has a subcosmopolitan distribution. Unlike other duckweeds, it has submerged rather than floating fronds, except when flowering or fruiting. Also unlike other duckweeds, a large number of fronds remain attached to each other at a time.
Lemna gibba, the gibbous duckweed, swollen duckweed, or fat duckweed, is a species of Lemna (duckweed). It has a simple plant body, known as a thallus, which floats on the surface of the water and measures 3–5 mm (0.12–0.20 in) in diameter. A single root hangs down into the water. Found in a wide range of still or slow-flowing water bodies, this common duckweed can also grow on mud or damp rocks.
Lemna minuta is a species of duckweed known by the common name least duckweed. It is the smallest Lemna species. It is native to parts of the Americas, and naturalized in others; the exact native range is not known. It is found on other continents as a non-native introduction as well. The plant's distribution is ever-expanding; it has been spreading in Europe and it was described from Poland for the first time in 2007. In many areas it is a noxious weed, such as in Belgium.
Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family (Araceae), so often are classified as the subfamily Lemnoideae within the family Araceae. Other classifications, particularly those created prior to the end of the twentieth century, place them as a separate family, Lemnaceae.
Lemna aequinoctialis, the lesser duckweed, is a tiny, floating aquatic plant found in quiet waters in tropical and subtropical regions. Fronds are generally 3-nerved, green, up to 6 mm long. Flowers are 1-ovulate, the small utricular scale open on one side. Seeds have 8–26 ribs.
Najas tenuis is a species of aquatic plant found in freshwater habitats, especially still or slow-moving waters, like ponds and rice fields.
Lesser duckweed is a common name for several plants and may refer to:
Apiogalacturonans are a type of pectins known to be found in the walls of Lemna and Zostera marina. Substituted galacturonans are characterized by the presence of the saccharide appendant residue D-apiose in the case of apiogalacturonan, branching from a backbone of D-galacturonic acid residues. According to the Complex Carbohydrate Research Center, "[t]he backbone of these polysaccharides is resistant to fragmentation by microbial EPGs."
Lemna turionifera is a species of flowering plant belonging to the family Araceae.
