Hmmm. Interesting. I see that Wikipedia does show the one with the white stripe down the middle as "Vittatum" (our database lists it as "Reverse Variegatum"), and the one with the white stripes on the outside as "Variegatum." I have the Variegatum and a couple of solid green ones that were produced by the Variegated one. I used to have one with the white stripe in the middle, but I lost half my plants to a freak freeze. What is odd is that all my plants are offspring of one original plant. Go figure.
Well, at least your mostly solid green ones look healthy. Maybe when they get bigger, it will become clearer which ones they actually are. You never know, they just might produce little variegated babies.
