Nymphaeales
The Nymphaeales are an order of flowering plants, including two families of aquatic herbs:
- Family Nymphaeaceae (waterlily family)
- Family Cabombaceae (fanwort family)
Sometimes the Cabombaceae are included within the Nymphaeaceae. The older
Cronquist system also included the following familes:
The Nymphaeales, taken in the narrower sense, appear to have diverged from the other flowers very early on.
