The correct name is Quercus orocantabrica. The source listed by POWO (Vila-Viçosa et al, 2022: https://revistas.ucm.es/index.php/MBOT/article/view/79286/4564456561777) mistakenly used Q. broteroana in the Early View version of the paper, but Q. orocantabrica has priority and this was corrected in the final pdf of the article.
you seem to be right according to the paper "Quercus orocantabrica Rivas Mart. & al. (2002: 706)=Quercus robur subsp. broteroana O. Schwarz (1937: 108) ≡Quercus broteroana"
Can you mail bi@kew.org to ask review it ?
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
