Description:

Geranium with palmately divided leaves. Given the location Geranium purpureum seems unlikely but the flowers were about half the diameter of the general run of Geranium robertianum.
Anther colour ambiguous - is this yellow (purpureum) or orange (robertianum?
Not enough detail of mericarps visible to resolve the identification.

Hi Lavateraguy, I similarly

Hi Lavateraguy, I similarly found G. purpureum-like plants outside the typical distribution. Pop the anthers under a stereomicroscope, if i remember well you should look at the anthers themselves and not the pollen. Hairiness is important too, colour of petals and how much the petal spread but in all good keys I've consulted (UK and continental ones) ripe fruits provide diagnostic charaters even for colour-blind people. So it is worth waiting a bit and collecting fruiting specimens! It look like a good contender...
