The glossy dark green, sometimes reddish brown tinged leaf blade is 50 to 70 centimeters long and 5 to 10 centimeters wide. It is covered with numerous, cloudy white to light green elongated spots. The spots are smaller on the underside of the leaf. The leaf surface is smooth. The piercing, brown-tipped teeth on the leaf margin are 2 to 5 millimeters long and 8 to 15 millimeters apart. The yellow leaf sap dries brownish.

The egg-shaped-pointed, white bracts have a length of 10 to 15 millimeters and are 8 millimeters wide. The bright pink flowers are light yellowish at their mouth and stand on 10 millimeter long flower stalks . They are 27 to 33 millimeters long and briefly narrowed at their base.
