Eucharis grandiflora: UV induced fluorescence and reflected colorful UV photography II

This is again about: Eucharis × grandiflora, also called Amazon Lily this time using my "work horse" UV filter, the Baader-U filter and a Hamamatsu f3.5/50mm quartz fluorite lens. Light source was an UV enhanced Xenon flash and a Nichia UV torch for the UV induced stimulated visible fluorescence (UVIVF) shot.

Also here not much prominently visible UV pattern, except that the base of the flower, where usually nectar can be found, lights up, as well as its pollen does.

Stay tuned, more will follow on that fascinating subject...
