Barclaya longifolia. 1 sm/md rosette. These plants develop long, deep red leaves. They resemble Cryptocoryne but are actually a member of the water lily family (Nympaeaceae).

Currently growing with CO2 but I will be transitioning a few plants to non-CO2 tanks this week. Winner can decide which they'd prefer. Will try to take better pictures of them once the algae clears up.
