One of the most UV-reflective flowers ever recorded by me, Geranium sanguineum is widely distributed in Europe mainly on calcareous soils. In Scandinavia it has a southern distribution. The veins on the petals show prominently in UV, but there are no basal markings of the kind seen for example in Potentilla (Rosaceae), merely veins being thickened and fused at the base of each petal. Style and anthers are very UV-dark, though.

 

Specimen from the Botanical Garden of Oslo University, Norway, 21 June 2010.
