Growing in river meadow. Possibly Geranium pratense.

"Meadow Cranesbill" is sufficiently widespread in its use to justify including in the identification.
I know that some "common" names are not common at all - especially when one moves away from the most well-known species - and hence are not always a justified inclusion. But when they are exactly that, I always like to use and to see them. For one thing, so many of the systematic ones have changed since I learnt - and mostly later forgot - the blessed things!
