Najadales
 |
Najadales is a botanical name of an order of flowering plants. A well-known system that used this name is the Cronquist system (1981), that used this name for an order in subclass Alismatidae with this circumscription:
- order Najadales
- family Aponogetonaceae
- family Scheuchzeriaceae
- family Juncaginaceae
- family Potamogetonaceae
- family Ruppiaceae
- family Najadaceae
- family Zannichelliaceae
- family Posidoniaceae
- family Cymodoceaceae
- family Zosteraceae
The APG II system, used here, assigns the plants involved to the expanded order Alismatales, in the clade 'monocots'.
