No problem. 'New River' is probably more accurate, if it is that cultivar. 'Palm Beach Purple' may be a local name because it is so widely used.
It is 'New River' at this nursery but I think they said they are the same. They have a picture of it under varieties.

http://excelsagardens.com for tropicals, they have some really neat plants
http://agristarts.com for tropicals too, it looks like the alocasia has a different specific epithet (gagaena) than odora, but it says odora at Excelsa Gardens. I am not sure if they are synonyms.
