Plants 4-10 dm, forming small colonies (by rhizomes); branches ascending; twigs of current season grayish brown, puberulent and sparsely stipitate-glandular, becoming glabrate. Leaves: petiole 0.5-1.5 mm; blade light green abaxially, dark green adaxially, oblanceolate to obovate, 1.9-2.9 × 0.9-1.2 cm, subcoriaceous, base cuneate, margins entire, (scattered stipitate-glandular-hairy and ciliate, 6-8 cilia per mm), apex subacute, mucronate, surfaces persistently stipitate-glandular-hairy and sessile-glandular (often sparsely stellate-eglandular-hairy abaxially). 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). Pedicels 2-3 mm, stipitate-glandular-hairy; bracteoles 1-2, 2-5 mm.
