Peperomia aff. metallica

This small rosette-forming Peperomia is a wonderful terrarium specimen, only reaching 6-8 inches and having a very compact growth habit.  It is easy to grow and has wonderfully marked leaves, with a wide silvery-green stripe down the midvein, and dark maroon and red on the rest of the leaf.  Peperomia metallica is a Colombian species, but this one looks a bit different from the standard metallica so I am unsure if this one also originates from Colombia.  Either way, it is a South American species.
