Field Notes
It's early in the morning, the air is cold and there is frost covering the ground. There was a slight breeze and the sound of construction and cars was in the distance. As we were walking around we spotted red berries and round toothed leaves on a vine.

Supporting Evidence

The first thing that lead us to believe that this was oriental bittersweet was the vines wrapped around each other. The vines looked woody and some felt smooth.

The second thing that lead us to believe that this was oriental bittersweet was the leaves. The few leaves that were left were partially green with some signs of decay. The leaves were mostly round with a pointed tip and the sides were toothed.

The last piece that we found were red berries with yellow skin. This helped us determine that we found oriental bittersweet.
