Hi all
I thought it might be an Aglaonema or Anthurium, partially because Philodendrons have a leaf sheath on the newly developing leaf, and these don't look like they do.

There is a better picture in <"Are these monsters...">, it could be a Philodendron, and it is definitely <"an Aroid">.The plants in front of pic. is defenitely NOT Echinodorus (=swords). Most likely a Philodendron species - but could well be another Araceae.
