My friend Frank is trying to ID this flower growing in the woods and fields of Weir Farm, Connecticut. "I've since looked at this one again in the field. It has a trailing ground stem that is woody, reddish-brown, and other flower stems shoot off this stem. It lies tangled in the grass and other plants of the meadow, rather like a strawberry. I've looked at wild-strawberries, cinquefoils, even avens. All which could be flowering now, but none with this distinct slender white flower. Also look at various bramble berries, but the ground hugging, vining, stem seems wrong there." Any ideas?
