Leaves aromatic; petiole to 1.3 mm; blade 1.7–4.5 × 0.7–2.6 cm, base cuneate, margins pinnatifid or entire (in distal leaves), apex acute to acuminate, mucronate, with sessile glands adaxially. Inflorescences terminal compound cymes, 8.5–22 cm; bracts leaflike, lanceolate, 2.1–10.3 × 0.1–0.6 mm, generally absent in fruit.
