Key to Tasmanian Dicots
Lemnaceae 4b:30  
The Lemnaceae are a small family of tiny free-floating aquatic herbs that often mass together to form a carpet-like cover on still water bodies. The lack true leaves, and are reduced to a photosynthetic thallus that often lacks roots. The flowers are miniscule, and reduced to simple ovaries or stamens.

Tasmania has three native species in two genera of Lemnaceae, Wollfia (the smallest of all flowering plants) and Lemna.

A species of a third genus (Landoltia punctata) is rarely naturalised, and is not included in this key.
