What plant is this? (Ranunculaceae?)?
I have a wildflower growing in the wet part-shady areas of my yard in Michigan that I've been all over the internet and USDA plant database trying to identify. I thought it was a member of Ranunculaceae, since it looks so much like a tiny persian buttercup, but now I'm not so sure because I can't find anything that matches this flower exactly. I've uploaded (I hope) pretty thorough pictures here:

The main characteristics, as far as I can tell (not a botanist) are a hollow, diamond-shaped stem, small (1") very regular many-petaled flowers with a sort of waxy shine, seperate petals and green center. Two kinds of leaves, the first kind are on a separate stem and are palmate, deeply lobed. The second are only on the flowering stems and are a clump of three simple, elongated smooth-edged leaves. It is spreading rapidly through the shady, wetter area along the back of my house. Anyone know, even a common name?
The leaves are much different from the marsh marigold, although the flowers look identical. It's also in evenly moist soil, but not standing water. Could it be a variant of some kind?
inflorescence best answer:
Answer by Sandy G
It looks like a double marsh marigold (Caltha palustris var. 'Flore Pleno') to me, and the habitat sounds right.
inflorescence
Agrostis stolonifera
The inflorescence is an open panicle at anthesis where the branches have a whorled arrangement at each node. Maturity and exposure to sun seem to dictate how reddish the infloresence appears.
