Sparganium Typha
Typha

The TYPHACEAE /taɪˈfeɪsiː/ are a family of flowering plants . The botanical name for the family has been recognized by most taxonomists.

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
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.

The Cronquist system , of 1981, also recognized such a family and placed it in the order Typhales , in the subclass Commelinidae in class Liliopsida in division Magnoliophyta .

The Wettstein system , last updated in 1935, placed the family in order Pandanales
Pandanales
.

Members can be recognized as large marsh herbs with two-ranked leaves and a brownish compact spike of unisexual flowers .

The earliest fossils, including pollen and flowers, have been recovered from late Cretaceous deposits.
