Synonyms:

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
