I'm sorry that I have to change the name of this species again. Even though it was described in 1798 as Statice spicata and later transferred to the genus Psylliostachys as Psylliostachys spicata, this does not automatically mean that this is the currently valid scientific name:
According to the currently valid International Code of Nomenclature for algae, fungi, and plants, some names are changed according to the established rules. This can have various reasons, for example this is also the case if the epithet has the wrong gender:
Incidentally, many of the old racist names have still not been corrected at iNaturalist. This is work that is still awaiting us curators. I often take care of changes that were actually made years ago, which actually shows that we need more committed curators to take care of maintaining and updating the taxonomy. This backlog is therefore unfortunately not unusual...
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.
