Hi, Christine. You're not being a pain at all. We all want this database to be accurate, and reports like yours are the very thing that ensure its accuracy.
I'm going to wait until the shutdown is over. I need to find it in a taxonomic database, and after seeing that the subspecies of P. sanguisorba are now synonyms of S. verrucosa, I'm hesitant to merge this entry with P. minor. I'll act on this as soon as I have access to ITIS and GRIN.
