Stout, monoecious, rhizomatous perennial herbs rooted in mud. Stems erect, simple, without nodes, terminated by dense cylindric flower spikes. Leaves distichous, simple, linear, ± glaucous, entire, ± all basal, with long, open, but tightly clasping sheathing bases; the free part of the leaves usually twisted. Flowers unisexual, very numerous, densely crowded in a terminal spike, the male flowers in the upper part, the female flowers below. Male flowers subtended by scales or bracteoles; perianth 0 or of 3-6 small scales. Female flowers with or without bracteoles; perianth of slender hairs; abortive female flowers often present. Ovary superior, 1-locular with a solitary ovule. Fruit ellipsoid or subcylindric.

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), 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 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.
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.[2]

Sparganiaceae is the botanical name for a family of flowering plants. Such a family was previously 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 consists of only one genus Sparganium of less than two dozen species, perennial plants of wet habitats. By the APG III system of 2009, Sparganium had been found to be fairly closely related to Typha, and so was placed with that genus in family Typhaceae.
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.
