Leaves solitary, 1–2 cm apart; petiole stiff upright, 23–35 cm long, 2–3 mm thick, adaxially sulcate; leaf blade usually broadly ovate to ovate-oblong, 20–32 cm long, 9–11 cm wide, dark green, base broadly cuneate to suborbicular, abruptly narrowed to petiole, inequilateral, apex acuminate, margin entire, with prominent midvein on lower surface and 3–4 inconspicuous secondary veins at both sides. Peduncle erect or declining, purple, 9–11 cm long, with 7–8 bracts, bracts gradually wider from base to top of peduncle, the distal ones at base of perigone broadly ovate, purplish red, 22–28 mm long, 16–20 mm wide, apex obtuse.
