This one of the various ‘white’ species out of Ecuador. New growth is this crazy color and more mature growth has white leaf venation (in high light) and edges. The more mature leaves of ‘white’ are an emerald green with stark white edges. It is a slow growing species, and so far has stayed on the small side. Both of these species pictured below are probably a little paler than usual though, as they have been in very bright light recently.
