Mosyakin has shown that the name P. hirsutissima has been misapplied to eastern pasqueflower when Pulsatilla is maintained as a separate genus, and that the correct name for this species is P. nuttalliana. This encompasses both East Asian and North American material. The species may be further segregated into subsp. multifida (East Asian) and subsp. nuttalliana (North American) but I have not yet attempted to split these. I do follow Mosyakin in distinguishing these taxa from P. patens s.s.

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.
