Revision of Landoltia from Wed, 2013-09-11 12:01

Landoltia is a monospecific genus, probably native to SE-Asia and Australia but nowadays distributed throughout warm-temperate regions with mild winters and the subtropics (for instance in South America and South Africa). It is closely related with Spirodela and only recently segregated from it (Les & Crawford 1999). Its generic status, based on molecular phylogenetic research, was recently disputed by Ward & Hall (2010). Landoltia is morphologically very similar to Spirodela (several roots per frond) but phylogenetically closer to Lemna.
