Bog Yelloweyed Grass (Xyris difformis Chapm.)

Some authorities, including BONAP, separate some populations into the species Xyris curtissii. We use POWO's treatment, treating these as Xyris difformis var. curtissii. The only implication for the range map is that our map with the merged populations shows this species extending into the Southern Florida Coastal Plain.
