showed a dandelion with a bullseye pattern on it?

>UV light: The same specimen on Fuji RTP film using the UV-Micro-Nikkor
lens 105 mm f/4.5 and the FF Nikon filter (Wratten 18 A equivalent). Note
the colour differentiation of the flower head. These details are not found
in visible light.

I looked at the same web site, that was the one I remember and the film is
indeed indicated in the quote above from the dandelion illustration. Now,
does anybody know what Fuji RTP film is?
