Their broadly cup-shaped to fairly flat rosettes reach a diameter of 25 to 80 centimeters. Their inner leaves are more or less upright. The obovate, often folded lengthwise, yellowish green, almost bare, often sticky leaves are 7 to 50 centimeters long, 4 to 30 centimeters wide and 0.6 to 1.8 centimeters thick. Towards the point they are pointed or pointed. The base is narrowed or sometimes wedge-shaped. The lower part of the leaf margin is occasionally covered with a few scattered eyelashes that are up to 0.5 millimeters long. The leaves are sometimes reddish or brownish variegated , especially along the edge .

The seven to nine-fold flowers are on a 1 to 2 millimeter long, slightly downy-haired pedicel . Your sepals are weakly downy hairy. The whitish, intensely variegated, lanceolate, pointed petals are 3 to 5 millimeters long and 1 to 1.5 millimeters wide. The stamens are bare.
