The Hostapedia by
Mark Zilis (2009),
"This may be the same as Schmid's 'Urajiro Hachijo'. My
only reservation is that the origins of the two seem to differ.
This Japanese plant comes out of the commonly grown form of
Hosta rupifraga, though that species has often been confused
with H. longipes var. latifolia."
