Schmid (1991) described groups of plants that have the same basic structure and vary only in their leaf color. The cultivars listed are very similar to each other and some are probably identical i.e. the same plant but with a different name.

This group was defined as "...Ogon Tokudama, the "golden well-rounded hosta," originated with H. 'Tokudama Aureonebulosa', which is unstable in the long term and will occasionally sport to all-yellow forms which occur naturally as well as in tissue culture. Additionally, many different forms and sizes occur when this taxon is hybridized. A number of distinct clones and hybrids have been isolated and named. The horticultural "standard" form which is essentially identical to H. 'Tokudama Aureonebulosa', except  for the all-yellow leaves, is most often seen cultivated under the name H. 'Golden Medallion' but this name was registered without description. The former group name, H. 'Tokudama' Golden group, is too vague because distinct yellow mutants of H. 'Tokudama Flavocircinalis' also exist, and it has been replaced by the more specific name. Other distinct clones belonging to this group may exist and may be named in the future."
