Habit | Plants (3–)6–10 dm, forming small colonies; branches ascending to ± spreading; twigs of current season grayish brown, puberulent and glandular-hairy. | Plants 2–6(–10) dm, forming small to extensive colonies; branches erect; young twigs pale green, densely hairy (hairs relatively short, curled). |
Leaves | petiole to 1.5 mm; blade light green abaxially, shiny dark green adaxially, oblanceolate to obovate, 2–4 × 1–2 cm, subcoriaceous, base cuneate, margins entire (scattered stipitate-glandular-hairy and ciliate, 7–10 cilia per mm), apex obtuse to subacute, mucronate, surfaces persistently stipitate-glandular-hairy and sessile-glandular. |
petiole 2–3 mm; blade glaucous abaxially, dull green to yellowish green adaxially, ovate to oblong, 2.5–4 × 1–2 cm, subcoriaceous, base cuneate, margins entire, apex rounded to obtuse, surfaces glabrous or sparsely short-hairy (longer hairs ca. 0.1 mm) and sessile-glandular abaxially. |
Inflorescences | erect or arching, 3–7-flowered, bracteate, 2–5 cm, stipitate-glandular-hairy and hairy; bracts persistent, leaflike, 2–5 mm, expanding to 5–10 mm, longer than pedicels, densely stipitate-glandular-hairy (hairs 0.3–0.5 mm). |
drooping, 2–4-flowered, sometimes flowers solitary, bracteate, 1–2.5 cm, glabrous or pilose; bracts early-deciduous, leaflike or not, 5–6 mm, shorter than pedicels, glabrous, sessile-glandular. |
Pedicels | 2–4 mm, stipitate-glandular-hairy; bracteoles 1–2, 2–5 mm. |
8–15(–20) mm, glabrous, sessile-glandular; bracteoles 1–2, 1–2.5 mm. |
Flowers | sepals 5, 2 mm, densely stipitate-glandular-hairy (hairs 0.3–0.5 mm); petals 5, corolla white to pink or reddish, campanulate, 6.5–7.5 mm (averaging 7 mm), lobes triangular, 1.2–1.7 mm; filaments 0.3–0.5 mm, moderately hairy; anthers included, 3.2–4 mm (averaging 3.7 mm), thecae divergent distally; ovary stipitate-glandular-hairy (hairs 0.3–0.5 mm). |
sepals 5, (glaucous), 1–1.2 mm, glabrous, sessile-glandular or not; petals 5, corolla greenish white, campanulate-conic, 3–5 mm, lobes deltate, ca. 1 mm; filaments 0.5–1 mm, ciliate; anthers included (tips barely exserted), 2.5 mm, thecae not divergent distally; ovary glabrous. |
Drupes | juicy, insipid, black, 6–8 mm diam., moderately glandular-hairy. |

Discussion | Gaylussacia bigeloviana has been confused with G. dumosa; there are points of difference, including plant height, corolla size, vestiture, habitat, and the northeastern-centered range of G. bigeloviana. Occurrences in North Carolina are in large, peat-based pocosins that lie mostly within Carolina bay geomorphological formations. The single South Carolina population occurs in an Atlantic white cedar wetland. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Gaylussacia nana is a coastal plain endemic; it is distinguished by the glabrate and glaucous abaxial faces of leaves and the relatively large, glaucous to glaucescent fruits. Recent field work and herbarium studies have extended its known range. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
