There was a long discussion about whether iNat should use the hybrid formula Abronia maritima × umbellata that has been used in all recent scholarship or should substitute an earlier hybrid name (Abronia × alba) that had been resurrected from a 19th-century description. The majority view was that both forms are usable for a hybrid (unlike for a species, where there is one valid name) and iNat is free to choose whichever works best for iNat users.

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.
