This large size (19 inches high by 55 inches wide) botanical form of the species H. longipes was found in Japan by Dr. Fumio Maekawa in 1940. Its green leaves are slightly shiny on top, very shiny on the bottom and are broadly ovate in shape. It has dense clusters of pale purple flowers with purple anthers borne on 20 to 30 inch scapes in August into September followed by viable seeds.

According to The Hostapedia by Mark Zilis (2009), "This form differs from H. longipes by having green petioles, i.e. no purple-red dots."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Very variable in the wild, where many natural sports and seedlings are still being found. Many botanical forms are much used in breeding...A nearly flat, overlapping mound of wide leaves."
