Obs. Originally thought to be Aeonium ciliatum Webb & Berthel. × Aeonium nobile (Praeger) Praeger, but according to Bañares (2007) it is correctly Aeonium hierrense (R.P.Murray) Pit. & Proust × Aeonium nobile (Praeger) Praeger. The re-evaluation of the parentage does not affect the name of this nothospecies (Art. H.10 Note 2).

 

Description (according to Praeger, An Account of the Sempervivum Group, 1932) :

Stem very thick (2.5 cm in diameter), over 30 cm high in the barren plant, 75 cm high in the flowering plant, unbranched.

Rosette very large, flattish.

Leaves glabrous, very thick (3 mm at margin, 10 mm at centre), dark green, 15 x 7 cm, spathulate, rounded at apex with a short depressed apiculus, attenuate at base, margin red, with short distant conical patent hyaline cilia mixed with very fine pubescence.

Inflorescence more flat-topped than in ciliatum owing to the very long (to 25 cm) lower branches ; flower stem and branches crimson, with the calyx and outer face of the petals finely glandular-pubescent.

Flowers of a rather dirty red, petals whitish above, red at base with short crimson lines, filaments tapering, pink, ovaries white with crimson edges, styles crimson, anthers pale yellow.

 

The plant resembles an overgrown ciliatum, but the leaves are much more solid, approaching the unique massiveness of nobile. The leaves had the dark green tint of ciliatum and the leaf-margins combined the characters of the parents.
