USDA confiscated 2 packets of Aconitum seeds a few years ago. According to the paper enclosed, as there are prohibited species and the subject Aconitum packets were labeled only as species they could not rule out that they were not the kind prohibited, they had to be destroyed.
They were included in my package because I selected a number of packets within a range.
Now when I select seeds of a genus to be selected from a range of numbers, I make sure to exclude any that are described as "sp".
