Miscellaneous -- A. Camus : n° 152;
-- Section Quercus;
-- 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
varieties

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

2/ subsp broteroi (Cout.) A.Camus 1936
= Q. lusitanica subsp broteroi Mouillef. 1892
= Q. lusitanica var. broteroi Coutinho 1888
= Q. faginea var. broteroi (Cout.) A.Camus 1939
= Q. broteroi (Cout.) Rivas Mart & Saenz de Rivas 1991
= Q. hybrida Brotero 1804, nom. illeg., not Michx
= Q. lusitanica var. baetica Coutinho 1887
= Q. tlemcenensis (A.DC) Trab. 1905, & (A.DC) Villar 1937
rather tall tree with pubescent twigs and buds, and straight, hairy, decicuous stipules; leaves 4-11 X 2-6 cm , subpersistent, flat; greenish grey tomentum beneath, made of trichomes longer than the type-species (200-250 µ); apex rounded, base slightly attenuate; obtuse, rarely mucronated teeth (looking more crenate than dentate); 8-14 pairs of parallel lateral veins; no sinusal veins (or very few ones); half-cylindrical, slender, glabrescent, 5-14 mm long petiole; female flowers on a white tomentose peduncle; perianth with 6 tomentose lobes; 3 spatulate stigmas; cup with silky, convex scales; acorn 2.5-3 cm long, with pubescent stylopodium and convex scare; present in the South or the type-species range;
-- the variety maroccana (Braun-Blanq.& Maire) A.Camus 1935 is perhaps a hybrid with Q.canariensis.
-- Q. tlemcenensis is probably a variety = Q. faginea subsp broteroi var. tlemcenensis (A.DC.) Trabut & Batt.

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