There is an image of this cultivar on the Hosta Library.   A note over the image states: "Although the plant in the photo bears no resemblance to the former species 'Lancifolia', it is here because this plant was distributed for a while under this name. Whatever this attractive plant really is, it does not seem to have another name. A gold form of the plant 'Lancifolia' does exist, however, but it is uncertain whether it carries this name."
