Typha angustifolia Linnaeus. Narrowleaf Cattail. Phen: May-Jul; Jun-Nov. Hab: Brackish to fresh waters of marshes and swamps, usually tidal, and also inland in non-tidal wetlands (where probably only introduced). Dist: NS west to ND, south to SC, FL (?), LA, and TX (?); Eurasia. Stuckey & Salamon (1987) considered T. angustifolia an invasive alien in North America, but later studies suggest that it was native at least in coastal areas of ne. and Mid-Atlantic North America, and has expanded its range westward in recent decades (Shih & Finkelstein 2008). Ciotir et al. (2013) and Ciotir & Freeland (2016) suggested that T. angustifolia in North America is closely related to T. angustifolia in Europe, and its occurrence in North America may be a recent dispersal. For now, we consider inland populations as non-native, and populations in tidal settings along the Atlantic Coast as of uncertain nativity.
