Najadales Explained

Najadales is the botanical name of an order of flowering plants. A well-known system that used this name is the Cronquist system (1981), which used this name for an order in subclass Alismatidae with this circumscription:^[1]

• 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'.^[2]
