There are no significant taxonomic issues associated with this name. However, there is a degree of confusion over separation of L. gibba from L. minor when the former is not expanded and this may obscure differences in the distribution of the two species.
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Kumar, B. & Beentje, H.J.|

Lemna gibba is assessed as Least Concern as the species is widely distributed, common and faces no threats.
|Previously published Red List assessments:|
|Range Description:||Lemna gibba is distributed throughout the world in warm and Mediterranean climatic regions and is naturalised in Japan (Cook 1996). It is however absent from polar regions and from parts of the tropics. It is also present in most of Europe, South and South West Asia, Sri Lanka, NE & South Africa and South America. |
In India this species reported as present at Gujarat, Jammu and Kashmir, Punjab, Chattisgarh, Madhya Pradesh, Maharashtra (Lakshminarasimhan 1996), Kerala (Nayar et al 2006) and Tamil Nadu. In the Gulf of Mannar it is occasionally found on the mainland coast (Daniel and Umamaheswari 2001). Anand Kumar (2001) reported that this species is distributed throughout India.
It appears likely that Lemna gibba occurs throughout the Arabian Peninsula, with records from Saudi Arabia (Landolt 2001, Chaudhary 2001), Yemen (Wood 1997, Landolt 1986, Al Khulaidi in prep.), ARE (Jongbloed 2003) and Oman (Ghazanfar 1992).

This species has a stable population and can form large colonies in suitable habitats.
|Current Population Trend:||Stable|
|Habitat and Ecology:||This herb is free-floating and grows in the stagnant water (Anand Kumar 2001) of ponds, tanks (Lakshminarasimhan 1996), pools, ditches, and rice fields. The species is usually found in mesotropic to eutrophic waters (Cook 1996) and in water rich in nitrates and carbonate (Sharma et al. 2010).|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Use and Trade:||It is used indirectly in waste water treatment and is also in production of bio ethanol. It can contain high amounts of carbohydrate, cellulose and hemicellulose compared to other aquatic plants (Sharma et al. 2010).|
No threats have been reported for this species.
|Conservation Actions:||No conservation actions are known or likely to be needed for this species.|
