L. laevigatum reproduces sexually by seed and vegetatively through offshoots and as such this species can rapidly form dense floating or rooted mats on the water surface (USDA-APHIS, 2013). Hrusa F; Ertter B; Sanders A; Leppig G; Dean E, 2002. In: Aquatic weeds: the ecology and management of nuisance aquatic vegetation [ed. Limnobium was described as a genus in 1814 and contains only two species: L. laevigatum and L. spongia.L. The plant produces stolons which bear ramets which may be the main source of new plants where flowers are unknown. Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface. The dense mats of L. laevigatum have been reported to obstruct waterways, which reduces the quality or availability of irrigation water (DiTomaso, 2010). R. Raleigh, USA: Animal and Plant Health Inspection Service., 16 pp. It has been estimated that about 29% of the USA would be suitable for L. laevigatum to establish (USDA-APHIS, 2013). USDA-APHIS, 2013. This species has a high reproductive potential as it can reproduce both sexually by seed and vegetatively through offshoots. Treatments have included mechanical and hand removal and application of appropriate aquatic herbicides including diquat and glyphosate upon remaining plants. Frogbit (Limnobium spongia) Not available to ship to CA The green heart shaped leaves resemble a miniature waterlily and float on the waters surface. Limnobium laevigatum is a floating aquatic plant, and is a member of the family Hydrocharitaceae. On the surface, it forms a dense rosette of almost spherical leaves that grow long fragile roots. In California it has been introduced as an ornamental pond plant, and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento river delta and the San Joaquin River, and ponds and irrigation canals. some aquatic birds) and block light to the aquatic community below (Akers, 2010). Male flowers have petals and 6 stamens, while female flowers typically do not petals and have 3 to 6 divided styles. In Brazil L. laevigatum occurs in a wide range of habitats from the Amazon Rainforest, Caatinga (xerophilous thorny forest and scrub of the drylands of north-eastern Brazil), Central Brazilian Savanna, Atlantic Rainforest, Pampa (grasslands from Southern Brazil) and Pantanal (periodically flooded grasslands by the rivers Paraná and Paraguay in Central-Western Brazil) (Bove, 2016). CABI is a registered EU trademark. Limnobium laevigatum, or Amazon Frogbit, is a floating plant that is reminiscent of a large duckweed (Lemna minor). Plants have white, inconspicuous flowers that are around 1/2 inch wide. Female flowers have an inferior ovary, the fruit is a fleshy capsule 4–13 mm long and 2–5 mm in diameter, and seeds are 1 mm long, ellipsoid, and hairy. L. laevigatum is listed as a state Noxious Weed (List Q) by the California Department of Food and Agriculture (CDFA) and is subject to eradication (Calflora, 2016; DiTomaso, 2010). Limnobium spongia is more likely to form emergent leaves than L. laevigatum, which produces emergent leaves only when it becomes crowded. As a result this can decrease the biodiversity in an area (Akers, 2010). Heine (Hydrocharitaceae) becoming prevalent in Zimbabwe and Zambia. Rhodora, 94(878):111-134. Anderson L; Akers P, 2011. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Amazon Frogbit in captivity has two hazards to its health which aquarium owners can avoid: (1) water droplets on the tops of the leaves can rot the plant (they must be kept dry), and (2) some species of aquatic snail appear to like to eat the spongy material on the bottoms of the plant leaves (keep them near the center of the tank, not against the glass on the edges.). The name originated from Greek word λιμνόβιος, limnóbios — ‘dwelling in a lake’. It can also reproduce vegetatively through fragmentation of stolon segments which connect rosettes (Cook and Urmi-König, 1983). Floral variation and taxonomy of Limnobium LC Richard (Hyrocharitaceae). Limnobium laevigatum, or Smooth Frogbit can be distinguished from Limnobium spongia, American frogbit, by flower and leaf characteristics as well as range; American frogbit is not known to occur in western states unlike smooth frogbit.

There is currently very little information on the growth rates, nutrient requirements and cold tolerance of L. laevigatum which would help to provide information on the likelihood of this species becoming invasive in other countries. Amazon frogbit (Limnobium laeviatum) is an easy to care for, floating aquarium plant. The species has been introduced to California, USA and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento River delta and the San Joaquin River and ponds and irrigation canals. Catalogue of non-native vascular plants occurring spontaneously in California beyond those addressed in The Jepson Manual - Part I. Madroño, 49(2):61-98. With respect to its habit and morphology, L. laevigatum is very similar to Eichhornia crassipes (water hyacinth), which is widely recognised as a significant invader (Pieterse and Murphy, 1990). Although now regulated and subject to eradication in California, L. laevigatum is still grown and sold by the aquatic nursery plant trade. In one place in California 2,500 plants m-2 were recorded (Akers, 2010). 20 pp. It is native to Central and South America, though in recent years it has reported in North America as an invasive species. & Hook.f. Weed risk assessment for Limnobium laevigatum (Humb. ex Willd. Alien Aquatic Plants Naturalized in Japan: History and Present Status. Once introduced into a new area it is likely to spread rapidly due to its high reproductive potential and high propensity for dispersal (Anderson and Akers, 2011). It is now found throughout much of California, and continues to spread via releases and escapes from the aquarium trade. Anderson, Lars, and Pat Akers. After an initial quiet phase lasting about four years, it began to spread quickly (Akers, 2010). Acevedo-Rodríguez P; Strong MT, 2005. L. laevigatum originates from fresh water habitats of tropical and subtropical Central and South America (Encyclopedia of Life, 2016). There are reports of the seeds being spread by wind (Anderson and Akers, 2011). Cold temperatures are more likely to limit its distribution. The California Department Of Food and Agriculture Hydrilla Eradication Program Annual Progress Report 2009. L. laevigatum is also similar to the closely related species L. spongia. Propagules of L. laevigatum can be dispersed by birds (Akers, 2010). (Crecimiento y propagación de Limnobium laevigatum (Hydrocharitaceae) bajo diferentes concentraciones de nutrientes.) When several references are cited, they may give conflicting information on the status. ex Willd.)

L. laevigatum reproduces sexually by seed and vegetatively through offshoots and as such this species can rapidly form dense floating or rooted mats on the water surface (USDA-APHIS, 2013). Hrusa F; Ertter B; Sanders A; Leppig G; Dean E, 2002. In: Aquatic weeds: the ecology and management of nuisance aquatic vegetation [ed. Limnobium was described as a genus in 1814 and contains only two species: L. laevigatum and L. spongia.L. The plant produces stolons which bear ramets which may be the main source of new plants where flowers are unknown. Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface. The dense mats of L. laevigatum have been reported to obstruct waterways, which reduces the quality or availability of irrigation water (DiTomaso, 2010). R. Raleigh, USA: Animal and Plant Health Inspection Service., 16 pp. It has been estimated that about 29% of the USA would be suitable for L. laevigatum to establish (USDA-APHIS, 2013). USDA-APHIS, 2013. This species has a high reproductive potential as it can reproduce both sexually by seed and vegetatively through offshoots. Treatments have included mechanical and hand removal and application of appropriate aquatic herbicides including diquat and glyphosate upon remaining plants. Frogbit (Limnobium spongia) Not available to ship to CA The green heart shaped leaves resemble a miniature waterlily and float on the waters surface. Limnobium laevigatum is a floating aquatic plant, and is a member of the family Hydrocharitaceae. On the surface, it forms a dense rosette of almost spherical leaves that grow long fragile roots. In California it has been introduced as an ornamental pond plant, and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento river delta and the San Joaquin River, and ponds and irrigation canals. some aquatic birds) and block light to the aquatic community below (Akers, 2010). Male flowers have petals and 6 stamens, while female flowers typically do not petals and have 3 to 6 divided styles. In Brazil L. laevigatum occurs in a wide range of habitats from the Amazon Rainforest, Caatinga (xerophilous thorny forest and scrub of the drylands of north-eastern Brazil), Central Brazilian Savanna, Atlantic Rainforest, Pampa (grasslands from Southern Brazil) and Pantanal (periodically flooded grasslands by the rivers Paraná and Paraguay in Central-Western Brazil) (Bove, 2016). CABI is a registered EU trademark. Limnobium laevigatum, or Amazon Frogbit, is a floating plant that is reminiscent of a large duckweed (Lemna minor). Plants have white, inconspicuous flowers that are around 1/2 inch wide. Female flowers have an inferior ovary, the fruit is a fleshy capsule 4–13 mm long and 2–5 mm in diameter, and seeds are 1 mm long, ellipsoid, and hairy. L. laevigatum is listed as a state Noxious Weed (List Q) by the California Department of Food and Agriculture (CDFA) and is subject to eradication (Calflora, 2016; DiTomaso, 2010). Limnobium spongia is more likely to form emergent leaves than L. laevigatum, which produces emergent leaves only when it becomes crowded. As a result this can decrease the biodiversity in an area (Akers, 2010). Heine (Hydrocharitaceae) becoming prevalent in Zimbabwe and Zambia. Rhodora, 94(878):111-134. Anderson L; Akers P, 2011. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Amazon Frogbit in captivity has two hazards to its health which aquarium owners can avoid: (1) water droplets on the tops of the leaves can rot the plant (they must be kept dry), and (2) some species of aquatic snail appear to like to eat the spongy material on the bottoms of the plant leaves (keep them near the center of the tank, not against the glass on the edges.). The name originated from Greek word λιμνόβιος, limnóbios — ‘dwelling in a lake’. It can also reproduce vegetatively through fragmentation of stolon segments which connect rosettes (Cook and Urmi-König, 1983). Floral variation and taxonomy of Limnobium LC Richard (Hyrocharitaceae). Limnobium laevigatum, or Smooth Frogbit can be distinguished from Limnobium spongia, American frogbit, by flower and leaf characteristics as well as range; American frogbit is not known to occur in western states unlike smooth frogbit.

L. laevigatum is a floating aquatic plant native to fresh water habitats of tropical and subtropical Central and South America. Scientific name of the kind was fist published in 1814 in the article of a French plant biologist Louis Claude Marie Richard in the 12th issue of Mémoires de la Classe des Sciences Mathématiques et Physiques de L’Institut National de France. These species have not previously been recorded as naturalised in Queensland. In addition to this their distributions are different as L. spongia is not known to occur in Western States unlike L. laevigatum (Encyclopedia of Life, 2016). It has been reported in areas surrounding Redding and Arcata, the Sacramento River delta and the San Joaquin River and ponds and irrigation canals (Calflora, 2016; Encyclopedia of Life, 2016). A pest report from California suggests that the floating mats will probably alter many ecosystem processes such as carbon and nutrient cycling. Kadono Y, 2004. Seeds and fragments of stolons are naturally dispersed by water and wind and can also be accidentally transported by birds and as hitchhikers on watercrafts.
