Hi Tony
Apologies for not seeing this one - I try my best but I'm as fallible as the next man.
The name does exist [tvk NBNSYS0500000062] but it has been marked 'redundant', which is a flag that is used to remove some taxa that have been deemed unnecessary for recording purposes (e.g. some sub-ranks, exotic species or aggregates that have come from non-standard sources) but it can easily be switched back on again. I don't have a record of why it was marked redundant but, given that you have records, I will switch on the 4 related "Rosa canina group" aggregates now.
Were you attempting to enter the records into iRecord or into Recorder?
Best wishes,
Chris R.
