Contributions from the United States National Herbarium, volume 52:415 pp. Depending on the treatment, the two species within the genus Limnobium are either maintained as different species or they are placed within one species but as two different varieties (L. spongia var. Spongeplant: A new aquatic weed threat in the Delta. The Hawkesbury River County Counsel (2014) have also declared this species to be a Noxious Weed in an area close to Sydney, Australia and therefore requires its removal. It is native to Mexico, Brazil, Antigua, Cuba, Dominican Republic, Guadeloupe, Martinique, Montserrat, Puerto Rico, St. Lucia, Trinidad, Costa Rica, El Salvador, Guatemala, Nicaragua, Panama, French Guiana, Guyana, Suriname, Venezuela, Argentina, Chile, Paraguay, Uruguay, Colombia, Ecuador and Peru (Bove, 2016; USDA-ARS, 2016). However, in a more recent paper Lowden (1992) proposed that Limnobium Limnobium spongia subsp. 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. 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 … Although L. laevigatum is now regulated and subject to eradication in California (USDA-APHIS, 2013), it’s still grown and sold by the aquatic nursery plant trade (Hrusa et al., 2002) so new introductions are likely. Aquatic Botany, 77(4):257-276. According to the USDA-ARS (2016) it is native to Chile however Hyde et al., (2016) state that L. laevigatum is not present in Chile. Limnobium laevigatum is a floating aquatic plant, which can be mistaken for water hyacinth (Eichornia crassipes) due to their superficial similarity. [English title not available].

It can also reproduce vegetatively through fragmentation of stolon segments which connect rosettes (Cook and Urmi-König, 1983). Limnobium spongia is more likely to form emergent leaves than L. laevigatum, which produces emergent leaves only when it becomes crowded. After pollination the pedicel of female flowers bends downward, forcing the fruit to develop in the water or in the mud (Cook and Urmi-König, 1983). Akers, Pat.
