Weird seed pod?
I found this tree in Frankfort Kentucky, and it has these seed pods all over it. I've tried to look it up, but I've found no match. What is it?
Kentucky trees and shrubs
It is Hop Hornbeam, Ostrya virginiana, a very desirable small to medium sized tree. https://plants.usda.gov/plantguide/pdf/pg_osvi.pdf
