Leaves: Leaves simple. Opposite. Blades narrowly obovate to oblong–spatulate, 12–40 cm long, 5–13 cm wide. Apex bluntly obtuse to acute. Base abruptly truncate or obtuse at juncture to petiole. Surfaces glandular punctate. Margins entire. Lateral veins ascending, connected by a deeply arched vein, midrib sulcate on upper surface. Petioles 2–10 mm long. Stipules absent.

Flowers: Flowers (3–)9–15 in axillary, cymose–fasciculate inflorescences, on lower stems below current leaves, peduncles nearly obsolete, pedicels 5–10 mm long, glabrous; bracts hirtellous when young.
