Par: Aeonium percarneum  (R.P.Murray) Pit. & Proust × Aeonium virgineum  Webb ex H.Christ

[or Aeonium canariense  (L.) Webb & Berthel. × Aeonium percarneum  (R.P.Murray) Pit. & Proust when A. virgineum is considered to be a variety of A. canariense]

Aeonium percarneum (R.P.Murray) Pit. & Proust × Aeonium virgineum H.Christ, Praeger, Semperviva of the Canary Islands area, Proceedings of the Royal Irish Academy 38 Sect.B (1): 479-480, t.12, fig. 19. (24 Sep) 1929.

Aeonium ×lemsii  G.Kunkel, Enumeración de las plantas vasculares de Gran Canaria, Monographiae Biologicae Canariensis 3(1): 40, 41. 1972.

Etym: Named for Kornelius Lems (1931-1968).

T: Islas Canarias, Gran Canaria, Cuesta de Silva, frequent in a valley on the E side of the road; also in the barranco E of Cuesta de Silva, near the road bridge; 1924, R. Lloyd Praeger.

HT: Citation of two original included elements, the author's specimen and Praeger's illustration, necessitated lectotypification.

LT: Sketch of a leaf in Praeger, Semperviva of the Canary Islands area, Proceedings of the Royal Irish Academy 38 Sect.B (1): t.12, fig.19. 1929. Designated by Bañares, Vieraea 35: 14. (Oct) 2007.

Obs: On p.41 of the protologue Kunkel stated that material was preserved in his own private herbarium, Herbarium kunkelianum, but this has not been traced. In Bañares (Vieraea 43: 194, 2015), Art. 40.4 is cited as a reason for a superfluous reneotypification, but that rule applies only to new taxa, while Aeonium ×lemsii G.Kunkel was already validly published.

 

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

Shrubby.

Stem short, erect, branched.

Branches patent, short, clothed below with withered leaves.

Leaves of the pale green of virgineum, sparcely and minutely pubescent, red-margined and streaked purple on back (as in percarneum), margin with short blunt cilia like those of percarneum mixed with pubescence as in virgineum.

Flowering time : March - April

Quite intermediate in stem and leaf characters.
