-- The specific name "lusitanica" must be avoided: it is too much ambiguous because applied to several species:
1/ Q. lusitanica Webb and auctores = Q.faginea Lam.
2/ Q. lusitanica Boiss. = Q. infectoria Oliv.
3/ Q. lusitanica Lam. = Q. fruticosa Brot.

-- The natural hybrids of Q. faginea are :
Q. x allorgeana, Q. x battandieri, Q. x coutinhoi, Q. x fagineomirbeckii, Q. x welwitschii, Q. x pacensis, Q. x salcedoi, Q. x senneniana, Q.x tingitana, Q. x villariana

Subspecies and

There are 2 sub-species:
1/ subsp faginea
the species described above, actually polymorphous.

2/ subsp. maroccana (Braun-Blanq. & Maire) F.M.Vázquez & A.Coombes 2016 Fol. Bot. Extremadurensis, 9: 27.
= lusitanica Lam. var. maroccana Braun-Blanq.& Maire 1924
= faginea var. maroccana (Braun-Blanq. & Maire) Camus 1935
= tlemcenensis f. maroccana (Braun-Blanq. & Maire) Villar 1938
= marianica C.Vicioso 1950 pro hyb.

This subspecies may also be considered as a hybrid between Q. canariensis and Q. tlemcenensis (= Q. x maroccana Villar 1943)

--- The taxon named Q. faginea subsp. alpestris (Boiss.) Maire 1960 is today described under the name x alpestris by F.M. Vàzquez & al. 2014: see this name.

-- The subspecies broteroi (Cout.) A. Camus 1936, which had been placed at a true species rank under the name Q. broteroi (Cout.) Rivas-Mart. & Saenz in 1991, is now renamed Q. tlemcenensis Trab. in Batt. & Trab. 1905 by F.M. Vázquez, Allen Coombes & al. 2018
