The Strelitziaceae comprise a family of monocotyledonous flowering plants, very similar in appearance and growth habit to members of the related families Heliconiaceae and Musaceae (banana family). The genera of Strelitziaceae have been included in Musaceae in some classifications, but are generally recognized as a separate family in more recent treatments such as the APG II system (2003). The APG II system assigns the Strelitziaceae to the order Zingiberales in the commelinid clade.
