The smooth, sparsely fuzzy-haired, sticky shoots are not patterned like a net and have a diameter of 1 to 5 millimeters. Their rather flat rosettes reach a diameter of 1.4 to 3 centimeters. Inner leaves are more or less upright and form a spherical bud in the dry season . The egg-shaped to obovate, green to yellowish, glossy, slightly downy-haired, sticky leaves are 0.7 to 1.5 centimeters long, 0.4 to 1 centimeter wide and 0.3 to 0.5 centimeters thick. The underside of the leaf is reddish striped, near the tip variegated with many brownish lines.
