Plants 1–3(–4) dm, forming small colonies; branches ascending; twigs of current season pale green, stipitate-glandular-hairy. Leaves: petiole 0.5–1.5 mm; blade light green abaxially, shiny dark green adaxially, oblanceolate to obovate, 2.5–4 × 0.3–1 cm, subcoriaceous, base cuneate, margins entire, (scattered stipitate-glandular-hairy and ciliate, 2–5 cilia per mm), apex obtuse to subacute, mucronate, surfaces scattered stipitate-glandular-hairy and sessile-glandular, adaxial surface sometimes glabrescent. Inflorescences erect or arching, 5–8-flowered, bracteate, 3–6 cm, stipitate-glandular-hairy; bracts persistent, leaflike, expanding to 5–12 mm, equaling or longer than pedicels, hairy and stipitate-glandular-hairy.

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.
