I found this tropical plant in a Manila nursery. But they do not have the real name. The underside of the leaf is colored deep dark pink and the top side of the leaf has that raised green spots/veins. Leaf felt rigid and not soft like a Dieffenbachia. Local translation of the name they call it is like they are calling it alligator leaf.
perhaps in reference to the raised green spotty veins. They grow it in shady side of the garden and as with most tropical plant loves moist media.
Anyone knows this one?
