Haeckel, 1866
- Subkingdom: Viridaeplantae
Cavalier-Smith, 1981 - Green Plants
- Phylum: Tracheophyta
Sinnott, 1935 Ex Cavalier-Smith, 1998 - Vascular Plants
- Subphylum: Euphyllophytina
- Infraphylum: Radiatopses
Kenrick & Crane, 1997

Kenrick & Crane, 1997
- Subphylum: Euphyllophytina
- Phylum: Tracheophyta
Sinnott, 1935 Ex Cavalier-Smith, 1998 - Vascular Plants

The Subclass Nymphaeidae is further organized into finer groupings including:
- Order (3): Ceratophyllales · Hydropeltidales · Nymphaeales
Orders
Ceratophyllales
Ceratophyllum is a of flowering plants, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. They are usually called hornworts, although this name is also used for unrelated plants of the division Anthocerotophyta. [more]
Hydropeltidales
Nymphaeales
Nymphaeales is a at the rank of order. When recognized, it includes water lilies and sometimes other aquatic plants. This order is not part of the APG II system's 2003 plant classification (unchanged from the APG system of 1998), which instead has a broadly circumscribed family Nymphaeaceae (including Cabombaceae) unplaced in any order. It is recognized by some systems of plant taxonomy, but others use different placements for the families in this order. In particular some plant systematists using the APG II system now use this order and circumscribe it to include the Nymphaeaceae and Cabombaceae. A 2007 study has found that Hydatellaceae also belongs to this group. [more]
At least 1,721 species and subspecies belong to the Order Nymphaeales.
