Ha!!!  I finally identified this plant!!  It is a flower found in Hawaii and Brazil (and obviously Mexico, as that is where I bought it) named Calathea Crotalifera,  also known as Rattlesnake Ginger. Strangely, it is a member of the mushroom family??? Hard to believe, but I read it on a horticultural site.   LWBUT, would you have known what it was??
