Discussion

Cosmopolitan. 13 species; 6 species treated in Flora.

Lemna rarely flower, but reproduction by budding is common. Daughter plants usually appear sessile but are connected to the mother plant by a short, thin, white stipe that decays after the daughter plant is grown. The exception is Lemna trisulca, in which the stipe is long and green and usually remains connected, resulting in a network of plant bodies. Vein morphology is best determined on fresh material using backlighting.
