The authorities used by iNaturalist all currently use Cornus unalaschkensis as the proper name for this taxon. The taxa Cornus unalaschkensis and Cornus x unalaschkensis are identical, but the x is occasionally added if an author isn't considering this to be a valid species, just a hybrid between Cornus canadensis and Cornus suecica.
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.
