Observation - Ranunculaceae?. Description: Growing in ancient woodland near a river. Quite shaded, a patch of them growing together within a small area, didn't see any in the rest of the wood. Have considered Aquilegia, Aconitum, and a few others but just not very sure at this stage of growth. Key

Growing in ancient woodland near a river. Quite shaded, a patch of them growing together within a small area, didn't see any in the rest of the wood. Have considered Aquilegia, Aconitum, and a few others but just not very sure at this stage of growth. Keyed out to Sanicle on one attempt but I don't think it is. Thanks for any help.
