Trollius europaeus, Globe flower.
A stamp issued by Finland in 1992 in a two stamp series named
FIELD FLOWERS
I was surprised to see Trollius europaeus in THE MEDITERRANEAN GARDEN SOCIETY journal index as this is a plant which lives in damp places, however, it is listed among other plants which could be seen on a trip to the Picos de Europa, Cantabrica, Spain in 2001.
I wonder if they saw all the plants listed?
