This plant is about 1 meter tall and growing in the shade on a hillside with limestoney (if that is a word) soil. The berries remind me of Sambucus (Elderberry) except the berries are not in a flat umbel but rather a cluster. The berries have a clear thin juice. The growth habit reminds me of viburnum. I really have no idea what it really is. Anybody know what this could be? It is at Buzzards Rock near Cincinnati, Ohio.
