Identifying hops is almost impossible. First, even on the same plant the leaves and cones vary, and they all have variations. If they are feral hops, you can guess, as in our area most feral hops on old farmsteads are cluster hops. If they were planted as an ornamental, those usually are just ornamental hops and not used in brewing.
But if it's a hop plant someone planted and doesn't remember what kind it is, it is not an easy task to try to identify it.
