This looks as much like a malachosticta hybrid as either of the actual parents (amphioxus and sp. sarawak).  Bright pink spots with leaves that are similar to sp. maura wahau in its growth habit.  Medium-sized, peltate, upright but looks as if it would be happy growing up a slanted surface or limestone wall.

The last photo is representative of the plants available. They are well-rooted and shipped meticulously in their pots.
