Typhaceae (incl. Sparganiaceae)
The familial boundaries of Typhaceae and Sparganiaceae have long been controversial. Both are probably better merged, as suggested by recent molecular phylogenetic research (APG III 2009; see also Stace 2010).
- Flowers in cylindrical spikes === Typha
- Flowers in globose heads (native) === Sparganium
