blades ovate-elliptic, obovate-elliptic, or ovate-lanceolate, (2–)4–12(–15) × 1–5(–6) cm, subcoriaceous, base narrowly to broadly cuneate, margins entire, flat or slightly undulate, apex acute or acuminate.

ocrea deciduous or partially persistent at maturity;

blade distinctly obovate or sometimes panduriform, 4–6(–7) × 2–4(–5) cm, less than 4 times as long as wide, coriaceous, base cuneate or truncate, margins entire, flat or crisped, apex obtuse.

terminal and axillary, usually occupying distal 2/3 of stem/shoot, usually dense, or interrupted in proximal part, broadly paniculate.
