Similar Species

Other water-lilies (Nymphaea and Nymphoides).  The non-native ornamental spatter-dock (N advena) is occasionally naturalised in the UK but is not recorded in VC55; it has erect leaves, not floating.  Note that some congested plants of the native N lutea may also have semi-erect non-floating leaves.
