Range Description: Lemna gibba is distributed throughout the world in warm and Mediterranean climatic regions, naturalized in Japan (Cook 1996) and absent in polar regions and 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 from 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). But 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.), U.A.E. (Jongbloed 2003) and Oman (Ghazanfar 1992).
