help me identify this plant i found by the river

Ohio Buckeye, Aesculus glabra is typically found growing in bottom lands along the banks of rivers and streams.

I live in martin city, kansas city, mo. I found this plant in the blue river parkway public fishing access right off holmes and blue river parkway. Theres a few big trees by the baseball diamonds, and numerous amounts of small plants down along the river path

QUOTE=Polycarp;12305314]True. It’s been a couple of years since I saw them, in the woods behind our former home here in rural NC. I guess my question is, “What plant is it that has leaves closely resembling those of buckeye/horse chestnut trees, but which is a ground-hugging herb rather than a tree or bush? Is it a taxonomic relative of them, or just something with similar leaf shape?” Location, of course, would be forest understory in the Carolinas. I didn’t see them flowering, so have no clue there; the unusual leaf shape was what made me take notice of them.

What you found in a van down by the river is clearly government cheese.
