Ruppia, also known as the ditch grasses, is the only genus in the family Ruppiaceae. Such a family has been recognized by relatively few taxonomists. The genus name was given in honour of Heinrich Bernhard Rupp, a German botanist (1688-1719).[1]
The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize such a family and places it in the order Alismatales, in the clade monocots.
According to the AP-Website the family is doubtfully distinct from the family Cymodoceaceae: the plants in the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae form a monophyletic group.
The Cronquist system, of 1981, placed the family in order Najadales of subclass Alismatidae in class Liliopsida [=monocotyledons] in division Magnoliophyta [=angiosperms].
Species include:
- Ruppia cirrhosa
- Ruppia maritima
- Ruppia megacarpa
