Very little is known about this cultivar, some sources suggest that it is synonymous with Ginkgo biloba ‘Bunki’. Bunki was a Japanese era name after Meiō and before Eishō. This period spanned the years from February 1501 through February 1504. The reigning emperor was Go-Kashiwabara-tennō.  However, this may be erroneous as one of the translations of bunki from Japanese is ‘forking’. Occasionally in the Ginkgo world a translation into the native language gives rise to a different name.
