This taxonchange affected some IDs of the plants that are commonly sold as Spiraea arguta but are actually the artificial hybrid between Spiraea cantoniensis and Spiraea trilobata. The correct name for these plants is Spiraea × vanhouttei.
Because this taxonchange was already committed i have added the name Spiraea × arguta as synonym to Spiraea × vanhouttei that it is easier in the future to find the correct taxon name.
It is not identical with the Spiraea arguta Hoffmanns. that is a synonym of Spiraea salicifolia L.
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.
