Field Notes
We think we have identified multiflora rose because the leaves are oval shaped, rigid, and have miniscule spikes. They are about 2 ½ inches long and 1 ¼ inches wide. They have tiny hairs on the undersides of the leaves, and few short and stubby red thorns along the stem. Clusters of red berries are hanging off the stem, and each berry is 1 cm wide and long. The wind and the leaves are rustling around me, as I’m standing on the paved sidewalk, facing the woods, and it seems as if the multiflora rose is a protective barrier to the woods. I can tell the difference between the multiflora rose and the different species on the site by the ridges on the leaves.

Supporting Evidence
Photo of my evidence.
We found a bush that had small red berries, or rosehips, like the ones pictured on the species identification card. It says that these berries appear in fall, so our information matches up.

Both the berries and the leaves were close to the size requirements given.

The tiny red thorns also appeared to be the same as the ones described. They were arched and slightly flattened. Also as you can see in this picture, there are tiny hairs on the leaf bottoms and stipules.

It's hard to know exactly what to document, isn't it? That will be easier if you continue to work on plants.

For me, the fruits, leaflets and thorns in your photos tell me that this is in fact a rose. But the one thing that convinces me that your plant is specifically a multiflora rose is that little fringe on each side of the base of the leaf's petiole. That makes this rose different from all the other roses you might encounter.

Good job!
