The taxon Plantago coronopus subsp. humilis has in iNat the Italian common name “Piantaggine a Cuscinetto” but this name refers to something else (P. subulata L. and possibly also to P. humilis Jan ex Guss.). If I try to delete this common name I receive an error message “Name is too short (minimum is 1 character)”.
I think that P. coronopus subsp. humilis does not have an Italian common name since it is not accepted as an independent taxon in our checklist. So, how can I just delete its common name without substituting with another?
