ID Needed - Similar to Harbinger-of-Spring
I'm trying to identify a plant which is currently blooming in my woodland. It has very tiny (1/8 inch)white flowers with 5 rounded petals. The plants are quite common and about a foot high, with rounded,lobed leaves similar to harbinger-of-spring or something in the hemlock family. I'm unable to find anything that matches it any of my field guides. It's taller than harbinger-of-spring, later blooming I think, and it does not have a round bulbous root, or red anthers. I do not think it's harbinger-of-spring, but thought the comparison might help id it. Any body have any ideas of what it might be?
