Obs: In Bañares (Vieraea 43: 190, 2015), Art. 40.1 (lack of type) is cited as a reason for a superfluous reneotypification, but Praeger's sketch was referred to in the validation by Bramwell & Rowley as “1929: 469”, the place of publication of the protologue description, where there is also a reference to the illustration as “Plate X, fig. 6”. This is the only included element of Praeger's description and thus also of Bramwell & Rowley's validation.

 

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

Like castello-paivae but smaller ; larger and more branched than viscatum.

Leaves intermediate, green (not glaucous), subviscous, very minutely glandular-pubescent on face, back and edges (not glabrous).

Distribution : Canary Islands (La Gomera).

The plant looks like a small green castello-paivae, but the fine glandular-pubescence exactly matching that of viscatum,  and absence of cilia show the other parent.
