Shrubs ca. 3 m tall; branchlets dark brown, scabrous. Leaves densely clustered in apparent whorls; stipules small; petiole 3-6 mm, with paired glands at apex; leaf blade oblanceolate to subspatulate, 25-50 × 7-11 cm, both surfaces glabrous, base cuneate, obtuse, margins sparsely glandular-serrulate, apex acute to acuminate; lateral veins 14-22, arcuate anastomosing before margins.
