As far as I know, there is no reason to keep Asterolinon separated from Lysimachia, but to include Anagallis within Lysimachia.
As both names were already on iNat, I suggest to move Asterolinon into Lysomachia conformely to POWO and almost all recent floras...
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.
