The olive-green to dark green, occasionally reddish tinged leaf blade is 40 to 60 centimeters long and 6 to 9 centimeters wide. There are cloudy white spots on young shoots. The piercing, reddish-brown teeth on the leaf margin are 2 to 4 millimeters long and 10 to 15 millimeters apart. The leaf sap is dry yellow.
