The five to seven foliage leaves, which are narrowed sub-like, form loose rosettes . Your leaf blade is 10 to 15 inches long and 1 to 1.4 inches wide. On the cloudy green upper side of the leaf there are several scattered, cloudy, light green, lens-shaped spots towards the base. The greyish green underside of the leaf is covered with many cloudy, light green, lens-shaped spots. The spots are scattered there or occasionally arranged in interrupted transverse bands. The leaf surface is very slightly rough. The solid white, reddish-tipped teeth on the leaf margin are 1 millimeter long and 3 to 6 millimeters apart. The leaf sap is dry yellow.
