Field Notes
At 9:20 in the morning, it was a very windy and dark as we got off the bus at Kettle Cove Beach in Cape Elizabeth. We could hear other groups chatting over more groups. The strong wind was moving south and was making the waves sound like thunder when they crashed against the rocks. The air smelled like rotting seaweed. The tide was at ebb because the low tide happened at 8:26. We found the plant along the tan bridge and in the grass. When we took photos, the wind was very strong and the thorns were very sharp so it was hard to hold the plant still in the picture. As it is later in the season, there are fewer leaves and the rose hips are dry and wrinkly. We were very surprised that we found a flower.
Supporting Evidence

This is the Beach Rose because it matches the characteristics of the I.D. card. The leaves are dark green and brown. The leaflets have 5-9 leafs on each steam in a compound-pinnate style. Each leaf is shiny and wrinkly. All the leaves are oval-shaped. The rose hips are shiny and wrinkly because it is almost the end of the season for the plant. The photo shows all of these characteristics.

This is the Beach Rose because it matches the features of the species on the I.D. card. The stem is covered in lots of thin, straight, sharp and spiny thorns that are varying sizes, scattered along the stem. This is not a garden rose because it has many more thorns than a garden rose would have.

This is the Beach Rose because it shares similar characteristics to the I.D. Card. The flower is pink and has 4 petals. We believe we found this flower while it was missing a petal. It makes sense because it is late in the season and the petals should start falling out.

Great photos. It's impressive that were still some flowers hanging on this late in the season. Thanks for posting.
