Miscellaneous |
-- For C. Vicioso it is the hybrid between Q. canariensis and Q. cerrioides. -- For Govaerts
& Frodin, it is a synonym of Q.cerrioides,
but these Authors are in disagreement with A. Camus and O. Schwarz
(among others) who feel that Q. cerrioides is a hybrid between
Q. faginea and Q. pubescens.
According to C.Vicioso, Q.pubescens subsp pyrenaica
(one of the 2 parents of Q.cerrioides for Govaerts, with Q.canariensis)
is actually a hybrid between Q.pubescens and Q.faginea,
so everybody is satisfied...unless Q.anselmii is not a synonym
for Q.cerrioides... -- For F.M.
Vázquez, A. Coombes & al. 2018, this taxon is definitely
a hybrid
between Q. canariensis and Q. pubescens subsp. subpyrenaica,
hence it is a synonym of Q. x cerrioides |

Recently (2018) F.M. Vázquez et al. consider this taxon as a synonym of Q. x cerrioides |
