Oh man! A degree in horticulture and I don't know exactly what that is. It does look like a type of variegated philodendron though.
David, I think that may be the closest and most educated guess I get on this blog! Kinda suspicious it might be polyester.
David is correct. Specifically it is a variegated Philodendron maximum.
I am so proud of my intelligent readers (and jealous) :)
I think it's a recent Variegated form of giant Alocasia Macrorrhiza a.k.a. "Elephant Ears" or Taro.http://davesgarden.com/guides/pf/showimage/28447/
Ooh yes, that looks similar
