An article by W. George Schmid in The Hosta Journal  (1996 Vol. 27 No. 2) states that This is a duplicate, incorrect or outdated name for Hosta sieboldii 'Kifukurin Koba'.

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term kifukurin or ki fukurin as yellow edge(d) or yellow margin(ed) and the term koba as small leaf, 'Koba Gibōshi' or H. sieboldii.
