Ballard, Harvey E., Kartesz, John T., Nishino, Misako. A taxonomic treatment of the violets (Violaceae) of the northeastern United States and adjacent Canada. 2023. J. Torr. Bot. Soc. 150(1): 3-266. doi.org/10.3159/TORREY-D-22-00029.1 (Link)
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.
