Systematics

Flowers

The first description was as Sempervivum dodrantale by Carl Ludwig von Willdenow was published in 1809.^[1] Theodorus Hendrikus Maria Mes put the species in 1995 in the genus Aeonium.^[2]

A synonym in nomenclature is Greenovia dodrantalis (Willd.) Webb & Berthel. (1841).

Description

The species grows as a perennial, densely budding rosette plant, the offshoots on long thin, smooth stems. The cup-shaped or urn-shaped rosettes reach a diameter of 2 to 6 centimetres (0.79 to 2.36 in) and are tightly closed during the dry season. Their leaves are tightly packed during growth. The leaves are obovate to spatulate, pale glaucous greyish-green, 2 to 3.5 cm (0.79 to 1.38 in) long, 1 to 1.5 cm (0.39 to 0.59 in) wide and 1–2 mm thick; the leaf apex varies between pointed, rounded, or slightly notched. Towards the top they are rounded or truncated and are often finished. The base is broadly wedge-shaped or slightly narrowed. The leaf margin is translucent.^[3][4]

The flattened inflorescence has a length of 3 to 6 cm (1.2 to 2.4 in) and a width of 5 to 10 cm (2.0 to 3.9 in). The densely leafed peduncle is 10 to 25 cm (3.9 to 9.8 in) long. The 18 to 23-fold flowers are on a 2–4 mm long, glandular-fluffy flower stem. The sepals are glandular-fluffy. The deep yellow, reverse lanceolate petals are 6–7 mm long and 1–1.5 mm wide. The stamens are bare.^[5] The flowers are 24-merous in all of their parts (i.e. typically 24 sepals, 24 petals, 24 stamens and 24 carpels) ^[6]

Distribution

Aeonium dodrantale is restricted to the Macizo de Anaga (Anaga Peninsula) in the far east of Tenerife,^[3] occurring at heights of 150 to 1200 m.^{[citation needed]}
