Plants 1–2 m, branches spreading. Leaves: petiole 10–15 mm; blade oblong, lanceolate, oblanceolate, or elliptic, 3–8 cm, margins entire or spinulose-serrulate, apex acute to long-acuminate, abaxial surface sparsely pilose. Inflorescences fascicled or solitary, sessile, dense, 20–60-flowered, 4–10 cm; bracts ± persistent, ovate-deltate, 1.7–2.2 mm. Pedicels 2–2.5 mm.
