The leaves are basal, with petioles measuring 8–12 cm long and densely pilose with pale green lenticles. The leaf blade is asymmetric, widely ovate, 19–20 × 12–14 cm, with a caudate apex and oblique-cordate base. The margin is subentire, and venation is palmate with 6–9 primary veins. The leaf blade is fleshy and relatively flat, adaxially blackish-green along main veins, with random silver-white areas between the veins.
