Is this Homalomena?
I can't tell from googling. Leaves feel different from Dief, thicker and firmer, although it's similar looking. Also looks like it could be more variegated. Got it a couple weeks ago, not burning in morning sun until about 11, new leaves are coming out.
Oh-so-helpful generic tag is a hoot! It says "indoor foliage" on the front and on the back I learn this plant should grow 1-10 ft tall, 1-5 ft wide, and it will die below 50 or above 80 degrees. (It was outside in the covered section at WM.) Besides being the world's most temperature-sensitive plant, what do you think?
