I've checked my wild flower key, but couldn't find this flower. Can you ID it please? It was growing by a track in a coniferous woodland in Co. Sligo at about 200m, favouring the sunny (south facing)side. I attach photos of the leaves and flower. It was locally common and widespread within the small area we explored.
Thanks so much for this, I was just about to post a tentative answer to that effect after finding it on a Google image search using "Single leaf clasping stem". But thank you again, it's nice to be sure!
