Can anyone ID this seed? I don’t think it’s related to the leaves here, but idk for sure. It’s thin walled and hollow except for a little spikey seed. I have some at my house too, but idk which tree they come from. I thought it was a beech, but I guess those produce actual nuts?
I know the leaf on the right is the basswood, but I’m unsure about the one in the left. I think it’s from a bushier/smaller potential tree and not a large deciduous.
