Gaylussacia dumosa and G. bigeloviana have been confused due to a reliance on insufficient characters to distinguish them and due to descriptions and ranges that were based partly on misidentified specimens. Gaylussacia dumosa is a low shrub of the coastal plain and lower piedmont, with scattered occurrences in the upper piedmont and at moderate elevations in the mountains.
