Aesculus is hardly a word that would strike fear into anyone’s heart. Yet Ohioans take pride in their Buckeyes — the traditional nickname for the sports teams at The Ohio State University that was formally adopted in 1950, but informally used before even the turn of the 20th century. The nickname was derived from the innocuous-looking native tree nuts that can be poisonous to Gophers, Badgers, Wolverines, and many other more fierce-sounding mascots across the country.
