Field Notes
Some sites in the vicinity had recently been mowed, but there were some shrubs that were undisturbed. I was curious what species were there, and if there were invasives in that undisturbed clump.

Supporting Evidence
Photo of my evidence.
There were small, pea-sized rose hips. This is one way to tell multiflora rose apart from other rose species.

The leaf is compound pinnate with about 7 leaflets. This helps me know it is a rose species. The fringed stipule helps me differentiate it as multiflora rose.

Here is a better photo of the fringed stipule.
