Discussion | 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.

Of conservation concern. Gaylussacia orocola is known from five counties in western North Carolina, where it inhabits montane bogs in the Blue Ridge Mountains with other rare or disjunct taxa, such as Sarracenia jonesii, S. purpurea var. montana, and Myrica gale.
