Aeonium ×junionae Bramwell & G.D.Rowley, in Jacobsen & Rowley, Some name changes in succulent plants, Part V, National Cactus and Succulent Journal 28(1): 5. (Mar) 1973.
Etym: Not explained. Some authors have assumed that it derives from the Latin name for the island of La Palma, Junonia Major, but that is not certain. Rowley continued to use the original spelling so it was intentional and therefore should not be 'corrected'. Rowley's sense of humour is such that he may have decided to make Juniona an anagram of Junonia, and specific epithets can be arbitrarily formed from any source whatsoever (Art. 23.2).
T: Islas Canarias, La Palma, frequent where both parents occur together; 1924, R. Lloyd Praeger.
HT: Sketch of leaf, in Praeger, Semperviva of the Canary Islands area, Proceedings of the Royal Irish Academy 38 Sect.B (1): 471, t.10, fig. 8. (24 Sep) 1929. Autotype (Art. 9.1). The only included element.
Obs: In the Barranco Angustias, the presence of many plants "of identical character" suggests that there are allopolyploids at that location.
Description (according to Praeger, An Account of the Sempervivum Grouup, 1932) :
"Quite intermediate; often monocarpic.
Stem short or up to 30 cm high, branches few or none, when present short, horizontal.
Rosette large, 15 - 20 cm across.
Leaves broadly spathulate, apiculate, soft and fleshy, often reddish in upper part, usually glandular-pubescent, margin serrate-ciliate with robust deltoid forward-curved cilia mixed with pubescence.
Inflorescence and flowers intermediate.
Flowers pale yellow.
Habitat : Canary Islands : La Palma, frequent where the parents grow together, but occurring mostly as isolated plants.
Even when the rosette is glabrous as in ciliatum, the inflorescnece is glandular-pubescent, sticky and balsamiferous as in palmense."
