This white-flowered cinquefoil species show similarities to the Fragaria species as far as UV patterns are concerned. Outer areas of the petals have an intermediate UV reflectance, whilst there are areas near the petal base which absorb more strongly. So do the veins and taken together this gives a quite nice pattern to the flower.
