According to The Hostapedia by Mark Zilis (2009), this cultivar is "...identical to H. 'Lancifolia' in foliage and flower...". It was originated by David Stone of Connecticut and registered on his behalf by Peter Ruh of Ohio in 1987. The plant is of small size and had elliptic-shaped green foliage. It bears lavender flowers from late August into September.

In The Hosta Journal (1992 Vol. 23 No. 1) there is an article by Peter Ruh about the so-called David Stone Medium or Miniature hostas which went by a numbering system that started with DSM. This cultivar was called DSM #13 and was described as "Medium, leaves deep green, lanced-shaped, wavy edge, long purple-flecked stems, flowers lavender-pink, reblooms."

Named for fellow hybridizer, Pauline Banyai of Michigan.
