Vegetative characteristics
Aeonium cuneatum grows as a perennial , single or sometimes sprouting rosette plant . Its strong shoots are glabrous and smooth. Their cup-shaped rosettes reach a diameter of 15 to 50 centimeters. Inner leaves are usually tightly pressed together. The obovate to obovate-spatulate, almost bare leaves are 10 to 25 centimeters long, 5 to 8 centimeters wide and 0.5 to 0.9 centimeters thick. They are pointed towards the tip and have a little pointed tip. The base is wedge-shaped. The sometimes slightly wavy edge of the leaf is covered with conical eyelashes that are up to 0.4 millimeters long.
Generative characteristics
The inflorescence has a length of 18 to 60 centimeters and a width of 12 to 30 centimeters. The leafed inflorescence stalk is 12 to 30 centimeters long. The eight to nine-fold flowers are on a 1 to 6 millimeter long, slightly downy-haired pedicel . Your sepals are weakly downy hairy. The yellow, wrongly lanceolate, pointed petals are 6.5 to 7.5 millimeters long and 1.3 to 1.6 millimeters wide. The stamens are bare.
