While I've got a pretty good idea how to say "Boxelder" or "Ash-leaved Maple", I don't know how to say "Acer negundo". Does the first word start with an "Ace" sound or and "Ass" sound? Or is the emphasis the other way, sounding like "ah-Sir". Similar questions about "negundo", esp. "gun" or "goon". Is there a website that offers pronunication help for latin names? It seems I ran across one (might not have been trees though) that offered a rhyming phrase as a help, but I can't find it again. Any suggestions?
