Flowers photographed in ultraviolet and visible light. http://www.ultraviol...e-shasta-daisy/ Middletown, New Jersey, USA 03 September 2007 Cultivar in home garden Synonyms: Chrysanthemum maximum Chrysanthemum x superbum Comment: In the ultraviolet photo, note the increased amount of surface detail brought out by the shortwave ultraviolet light. In the 100% crop the raking light brings out the epidermal cell structure on the UV-dark corolla showing the conical cells, which in this case are rectangular and slightly domed.1 Reference: 1.
