The International Plant Name Index is known for standardising plant scientific names, including the standard forms of authors' names. I heard that one person's standard form may be chosen when publishing the first scientific name, and it must be unique. In my case it was very easy because my surname had not been used before, hence my standard form is 'Gaem' (I chose it and IPNI accepted it). However, IPNI changes some people's standard forms in order to abbreviate their surnames. For instance:
Kawasaki --> Kawas.
Fernandes --> Fern.
Please note that I do not refer to the cases where IPNI adds abbreviations of people's forenames to their standard forms. Ex.:
Barros --> R.Barros
