This small creeping species is a native of southern Europe and widely used as an ornamental plant. It easily escapes from cultivation and may become naturalised even in colder climates such as in the Nordic countries.
Material was collected and photographed near Oslo, Norway 13 Aug 2010.

Ultraviolet light: Nikon D40X (modified), UV-Nikkor 105 mm f/4.5 lens, Baader U2" (Venus) filter, Broncolor studio flash with uncoated Xenon tube.
From the original file (CYMB_MUR_I10081312423_UV.tif), I made two 100% crops to show better the amazing level of detail of the epidermal structures contained therein.


The first published UV signature of C. muralis was by Blum (2013): http://www.ultraviol...aved-toadflax/. My results are in principle identical, but the higher magnification discloses more details.
All photographs captured with the exact same camera and lens, by the way (D40X/UV-Nikkor). Just to illustrate how much more detail UV brings with it.
