description
Vegetative characteristics
Aeonium dodrantale grows as a perennial , densely sprouting rosette plant that forms offshoots on thin, smooth shoots 2 to 8 centimeters long . The cup-shaped or urn-shaped rosettes reach a diameter of 3 to 6 centimeters and are tightly closed during the dry season . Their leaves are tightly packed even as they grow. The obovate-spatulate, pale green, bluish tinge, initially very finely glandular, later bare leaves are 2 to 3.5 centimeters long, 1 to 1.5 centimeters wide and 0.1 to 0.2 centimeters thick. Towards the tip they are rounded or trimmed and are often edged. The base is broadly wedge-shaped or slightly narrowed. The leaf margin is translucent.
Generative characteristics
The flat-topped inflorescence has a length of 3 to 6 centimeters and a width of 5 to 10 centimeters. The densely leafed inflorescence stalk is 10 to 25 centimeters long. The 18 to 23-fold flowers are on a 2 to 4 millimeter long, glandular, downy-haired peduncle . Their sepals are glandular-downy hairy. The deep yellow, inverted lanceolate petals are 6 to 7 millimeters long and 1 to 1.5 millimeters wide. The stamens are bare.
