Paphiopedilum venustum and venustum album

I recently posted photos of Paphiopedilum venustum var. album and have posted before photos of the normal variety.  Here are the two of them together for comparison.  It is obvious that the album lacks any of the red or purple coloring of the normal variety.  The plants and flowers are very similar in size, but the leaves of the album variety also lack any red or purple coloring.  The species if from Bangladesh, India and Nepal.
