Helobiae is a botanical name, and is no longer valid. It was used in the Engler and Wettsteins systems of plant taxonomy for an order of flowering plants; in the latter system it had this circumscription:

• order Helobiae

  family Alismataceae

  family Butomaceae

  family Hydrocharitaceae

  family Scheuchzeriaceae

  family Aponogetonaceae

  family Potamogetonaceae

  family Najadaceae

The Cronquist system placed quite a few of the plants involved in order Alismatales, as does the APG II system, although it assumes a much expanded circumscription of the order.
