Discussion

The horizontal root system of Chamaecrista deeringiana, the only feature distinguishing this species from sympatric specimens of C. fasciculata, is inter­preted as an adaptation to its fire-prone habitat.

Chamaecrista deeringiana is locally abundant in central and southern peninsular Florida, and in western Florida northward into Baldwin County, Alabama; it has also been documented from Peach and Taylor counties, Georgia, and Harrison County, Mississippi.
