Inflorescences erect or arching, 4–8-flowered, bracteate, 2–5 cm, hairy and stipitate-glandular; bracts persistent, leaflike, 2–5 mm, expanding to 5–10 mm, longer than pedicels, densely stipitate-glandular-hairy (hairs 0.3–0.5 mm).

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.
