There are quite a few species in POWO that are “ungrafted”: in the database but not attached to a genus, sometimes because they’re pending evaluation for distinctness, and sometimes because POWO doesn’t recognize the genus that contains them and they have no name in the genus it does recognize. I used to be able to create taxon framework relationships to these taxa by leaving “Parent Name” in the External Taxa section blank, but when I attempt to do that now, I get an error message: “external taxa must have names and parent names”.
Was this part of the package that Scott rolled out to help manage the big sphaghetti-bowl taxonomic changes? It’s disrupted a certain amount of my work in ferns.
[amended–the number of taxa lacking relationships doesn’t seem to have increased by very much, so I don’t want to overplay the disruption, but it is a surprise, and I’m not quite sure how to fix the taxa that are affected.]
