Howdy friends! I was wondering if anyone has any ideas regarding the identity of the plant seed pictured below. It was recently found, among many, lying along the pathway of snowy railroad tracks in upstate NY. The seed looks and feels like a peanut, and has a slick, transparent skin that can be peeled away. Thanks!
It would be hard to ID it for sure, unless you can get it to sprout. Considering agriculture and shipping, my guess is Glycine max.
