This plant grows in depression marshes, ditches and freshwater ponds. It is a fairly common native plant found in the Everglades. It is used in native medicine.

Similar in appearance to Stillingia sylvatica, this one only grows in very wet areas and is much taller. It tends to grow on a single stem with only a few leaves near the top. The leaf margins are not entire, but appear to have tiny glands.
