Miscellaneous -- The plant named "x neomairei" by A. Camus is in fact the hybrid between Q. faginea subsp broteroi and Q. pyrenaica; the species described above is the hybrid between Q. faginea subsp faginea and Q. pyrenaica, so it must be named Q x numantina (on account of the illegitimacy of the name 'welwitschii');
