Petiole 12–50 cm long; lamina narrowly elliptic to narrowly ovate, 10–21 cm long, 2.5–4(–5)cm wide (length to width ratio 3.4–6.4); base attenuate; apex acuminate.

*CVU, *GipP, *Gold, *HSF, *MuF, *VRiv, *VVP. Also naturalised WA, SA, NSW, ACT, Tas. Native to Europe, northern Africa, western Asia. Occurs in roadside drains and near edges of dams, lakes and slow-moving rivers, particularly in the Echuca-Shepparton-Rushworth area.

Aston (1973) suggested that the anther length to width ratio of this species could be used to distinguish it from A. plantago-aquatica. However, there appears to be no significant difference in this ratio for the two species.
