species with a strong UV signature in the fashion of a
typical bull's-eye pattern. In addition, the radiating
veins in the petals also absorb UV strongly.
Bloody Crane's Bill has purplish-hued flowers, much more vividly coloured than any of the other large-flowered members of this genus occurring in Norway. Despite its intense colours, G. sanguineum is very similar to the other species in terms of its UV marks, sharing with the others the radiating ray pattern on the petals. Also, as is the case with most reddish or bluish-hued flowers, IR reflectance is high. This makes the colour rendition of the flower hues prone to misinterpretation by film or digital recording.
