Ghostly calatheas spp

Here are two photos of beautiful calatheas. The first one is from prolific gardener S.E. Dicker, taken in Australia. The other from the blog author, shot in Quezon Memorial Circle, in the Philippine Horticultural Society section. Our first guess is "calathea picturata var argentea"
