Lilium auratum Lindl.
endemic in Japan
Kew Gardens just accept 2 infraspecifics, Lilium auratum var. auratum and Lilium auratum var. platyphyllum, but especially Lilium auratum disposes of some extraordinary, showy flowers that we tend towards keeping strains apart according their parental plants which got pollinated or bulbs we received and cloned them directly from their scales (tc-iv-b).
