Discussion

Zizania palustris var. interior grows on muddy shores and in shallow water, mainly in the north central United States and adjacent Canada. It resembles Z. aquatica in its vegetative characters, and Z. palustris var. palustris in its pistillate spikelets. Crossing experiments (Duvall and Biesboer 1988) suggest that hybridization between the two may occur. Isozyme data (Warwick and Aiken 1986) do not support the hypothesis that Z. palustris var. interior is a hybrid.
