botanical name of a family offlowering plants . Such a family has been recognized by relatively few taxonomists.The
APG II system , of 2003 (unchanged from theAPG system , of 1998), does recognize such a family and places it in the orderAlismatales , in the clademonocots . The family consists of a single genus "Ruppia ", also known as the "ditch grasses".According to the [http://www.mobot.org/MOBOT/Research/APweb/welcome.html AP-Website] the family is doubtfully distinct from the family
Cymodoceaceae : the plants in the three familiesCymodoceaceae ,Posidoniaceae and Ruppiaceae form a monophyletic group.The
Cronquist system , of 1981, placed the family in orderNajadales of subclassAlismatidae in classLiliopsida [=monocotyledons] in divisionMagnoliophyta [=angiosperms] .External links
