This plant is likely either of the two species mentioned, but, I suppose it’s also possible it is neither of them! There is some debate as to what this species is, clearly! Whatever it is, it’s quite pretty, and easy to grow in terrarium conditions.  It is from Borneo and is epiphytic with dramatic bullate leaves.

Available plants are well rooted in 2″ pots.  They will be shipped potted.  The last photo is representative of the size plant you will receive.
