There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a small size hosta with blue-green leaves and greenish-yellow medial (center) variegation on some, but not all, of the leaves.. This non-registered cultivar was originated by Dr. Ralph (Herb) Benedict of Michigan. 

According to The Hostapedia by Mark Zilis (2009), "...has the appearance of being a Tardiana-type with variegation. It could also be mistaken for a less-than-mature 'Tokudama Aureonebulosa."
