Observations in California confirm that vegetative mats consisting of L. laevigatum move with the current and pile up wherever there is an obstruction. Mature plants grow up to 50 cm tall and have emergent leaves borne on petioles that are not swollen or inflated like the spongy leaf stalks of water hyacinth. 20 pp. The juvenile plants have a great capacity for distribution in that they are small, they float and can be easily and quickly carried along by water currents. Cold temperatures are more likely to limit its distribution. Media Release, New Noxious Weeds List., Australia 6 pp. Easily fades away and later roots appear on the main roots. Putzke J, 2009.

H. \Murphy, K. There is some confusion as to Amazon Frogbit, Limnobium laevigatum, and European Frogbit. Paris Collation L. laevigatum can reproduce sexually through flower pollination and seed production (Encyclopedia of Life, 2016). This means that it must be eradicated from land. The plants therefore accumulate in infrastructure for moving water and will likely jam weirs, dams, gates, and siphons, as well as being pulled into pumps where they will jam and damage the machinery. Limnobium spongia blooms from summer to fall. Weed risk assessment for Limnobium laevigatum (Humb.

Berkeley, California, USA: California Invasive Plants Council. All rights reserved. During high water, the plants may increase flood risk by piling against obstructions and clogging the channel (Akers, 2010). Limnobium spongia is more likely to form emergent leaves than L. laevigatum, which produces emergent leaves only when it becomes crowded. spongia and L. spongia var. Limnobium contains only two species, with L. laevigatum being more commonly cultivated for ponds and aquaria. Limnobium was described as a genus in 1814 and contains only two species: L. laevigatum and L. spongia.L. Aquatic weeds: the ecology and management of nuisance aquatic vegetation. The species is monoecious (there are separate male and female flowers on the same plant) (Acevedo-Rodriguez and Strong, 2005) and plants are autogamous (pollen from male flowers pollinate female flowers on the same plant). 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). Compared with the North American frogbit species Limnobium spongia, which is only rarely cultivated in aquaria these days, it is much more adaptable especially regarding temperature. Heine HH, 1968.

Limnobium Laevigatum is a floating aquatic plant and a member of the family ‘Hyadrocharitaceae’: this is a flowering plant family comprising 16 known generas with a total of about 135 known species which includes the popular Amazon frogbit. This includes states in the western coast of the USA (Washington, Oregon and California) and the southern states (Texas, Arkansas, Louisiana, Mississippi, Alabama, Georgia, South and North Carolina, Florida, Hawaii and parts of Arizona and New Mexico).

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). This suggests that there may be a seed bank (Akers, 2010). South-American frogbit is a popular floating plant for aquaria that is rather undemanding and grows fast. Young plants grow in swirling rosettes which lie flat on the water's surface. Floating leaves on petiole 0.5-1 cm long with rounded round blade. Limnobium spongia subsp. Limnobium laevigatum (Humb.

It is also good in traditional aquariums, because the fine, long and decorative roots provide protection to gouramies and other surface fish that like the roots of floating plants. It is good that the water level is well lit (it grows poorly in dimly lit places), it did not move much (brittle roots could break when the water level is turned).
