POWO lists V. pallens as a synonym of V. palustris var. palustris (based on the ID of the type), but "V. pallens" and "V. macloskeyi var. pallens" as IDs have been widely used to mean what is currently meant by "V. minuscula". This change reflects that (actual) usage.
Plants ID'd as "V. macloskeyi" (without a variety designated) in eastern North America presumably also refer to V. minuscula - that will be handled in another taxon change.
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.
Is the swap for ssp. pallens also going to be into V. minuscula?
