The dashed line shows the northern and western limits of baldcypress (Taxodium distichum). The predicted limits of I. walkeri are made to coincide with the limits of the pondcypress variety of baldcypress (Taxodium ascendens.)

Pondcypress is characteristic of still-water swamps, whereas baldcypress is characteristic of flowing-water swamps. Both baldcypress and pondcypress occur throughout the range of pondcypress. Some consider the two to be varieties of a single species.
