Cymodoceaceae is the botanical name
of a family of flowering plants, sometimes known as the "manatee-grass family". Many taxonomists have not recognized this family.
The APG II system
, of 2003 (unchanged from the APG system
, of 1998), does recognize Cymodoceaceae and places it in the order Alismatales
, in the clade monocots. The family includes five genera, totalling 16 species of marine plants occurring in tropical seas and oceans (so-called seagrass
es).
According to the AP-Website it is doubtful if the family Ruppiaceae
is distinct enough to be kept apart: the plants in the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae
form a monophyletic group.
