The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes this family, and assigns it to the order Poales in the clade commelinids, in the monocots. The family then consisted of one genus (Typha), totalling a dozen species of perennial plants of wet habitats. More recently, the APG III system of 2009 included a second genus, Sparganium, in this family. The two genera together have a total of 51 known species.
