Hello,
I think both photos posted by skylark are not P. mamei, but P. plowmanii. I have both as live specimens. Mamei's foliage is more like the first photo by robertduval14: veins are closer together, silver freckles are small. The plant is entirely green. Plowmanii has really pronounced pink coloration and ruffles on the petiole, just like I'm seeing in the closeup by skylark. The veins are also farther apart and silver coloring on the front of the leaf is more subdued and "splash"-like rather than little freckles.
I could be wrong, but saw these photos on the front page and it stuck out to me!
