I agree with Kent and I can only repeat what I said once before when we had this conversation:
"I'm not opposed to the addition of these fields, but I do question the need to migrate the data from the fields in the custom databases. They're all set up in different ways. Some include the country of origin. Others have special wording ("Discovered by ...") for sports. I'm sure there are other items of this information that are specific to the particular type of plant. I personally appreciate the custom databases and I think excessive uniformity in data entry methods could rob them of their special character."
