Adam,
But there must be some good reason to overturn the priority, or the
original question would not be asked? If there is no good reason to
argue the case, why would this come up? And, it was a question about "
I am faced with a situation where two generic names have been extremely
widely used over the last several decades, but the older name has had
been used since 1899" so it is not about species names, but generic
names. There is something (I hope) missing that would favor the younger
name (or this is pointless)?
