Amazon Frogbit, Limnobium laevigatum detected naturalized species in Western Australia. The dense mats of L. laevigatum have been reported to obstruct waterways, which reduces the quality or availability of irrigation water (DiTomaso, 2010). Aquatic weeds: the ecology and management of nuisance aquatic vegetation. Limnobium spongia is more likely to form emergent leaves than L. laevigatum, which produces emergent leaves only when it becomes crowded. This can dramatically change the habitat structure, limit access by other species (e.g. Natural habitat of the kind is on South-East of the USA (its northern boarder – Illinois, Indiana and West V… It occurs in rivers, ponds, lakes, canals and other aquatic habitats (Cook and Urmi-König, 1983). http://www.eol.org.

Hydrocharella echinospora Spruce ex Benth. Limnobium laevigatum can reproduce and distribute sexually through flower pollination and seed production, and also vegetatively through fragmentation of stolon segments. 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). http://www.zimbabweflora.co.zw.

A weed risk assessment by USDA-APHIS (2013) for L. laevigatum rated this species as ‘high risk and a ‘major invader’. Petioles are always inflated. Floral variation and taxonomy of Limnobium LC Richard (Hyrocharitaceae). The use of choppers and shredders however often result in the small seedlings breaking off and spreading into new areas (DiTomaso et al., 2013).
