In the Rye and Hislop paper I cited as the source for this change, the two I. buxifolius varieties were collapsed into I. spathulatus. Since then, a paper has recently been published (see https://onlinelibrary.wiley.com/doi/10.1002/tax.13129) describing two new subspecies of I. spathulatus. Hence, I here swap the two buxifolius varieties into I. spathulatus subsp. spathulatus instead of into I. spathulatus

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.
