Red Berries in the Forest

There are lots of red berries in the woods right now. Consistent summer rains have made for a bumper crop. Here's some help in distinguishing between them all.

Asian photinia (Photinia villosa) is a robust exotic shrub that reaches twenty feet high and can be found singly or in dense stands. The leaves are "obovate", meaning they are often widest towards the tip. The berries are in terminal clusters.

Winterberry (Ilex vericillata) is a native shrub typically found in lowlands. At Mountain Lakes, its leaves are still showing a little green, and the berries are tight against the stem, rather than in terminal clusters.

Swamp rose (Rosa palustris) is another native, also found in lowlands. Its hips are larger than those of the exotic multiflora rose, and its thorns are not curved backwards like the fishhook-shaped thorns of multiflora rose. Also, the thorns of swamp rose are more dense towards the base--the opposite pattern found on multiflora.

I'm calling this Viburnum dilitatum, the linden Viburnum--an exotic shrub that is proving fairly invasive. It's leaves could be mistaken for the native Viburnum dentatum, but are wavier and less toothed along the edges.
