Field Notes
Day one of our experiment we tried to find Oriental bittersweet (Celastrus Obriculatus). We are sure that we’ve located bittersweet, and we are almost positive it’s Oriental Bittersweet, but there is a small possibility that it may be American Bittersweet. The two are easily mistaken because they are very similar with only subtle variations. Our location was next to the school sports field and near a residential neighborhood. Our specimen was growing on a pile of large loose rocks. Bitter Sweet has a massive root system, that is probably what enabled it to grow where it did. The day was cold and blustery and there was gray overcast looming in the sky. It grew in several small isolated clusters that were low to the ground (observe that a few meters away from our quadrat there was more Bittersweet up high in a dense thicket.) On our second day of the observation it was 49ºf. It had rained the night before so the ground and the air was still rather damp and the air still had a nip to it. The trip to see our plant was always around, 9:00-9:30am so our minds were sharp for observation. We wrote down some notes and gathered more pictures. Once we got all of our information we proceeded to make an outline of how we were to create our website page. We are almost positive that we found our plant because on an American Bittersweet the skin is orange and on an Oriental the skin in yellow. On our plant the skin was very yellow. Also the leaves were a glossy green with long pointed tip. The stem seemed older, round and bumpy, just like the species card stated. We are positive now that our plant is Oriental Bittersweet.

Supporting Evidence
Photo of my evidence.
We are positive that we found Oriental Bittersweet because, in this photo the skin around the berries is a bright yellow. On American BitterSweet (another type of native bittersweet that is similar to the invasive Oriental Bittersweet) the skin is an orange. This is proof that out plant is indeed Oriental Bittersweet. It also says on species card, that the leaves alternate off of the stem which you can clearly see in the photograph above.
Photo of my evidence.
This picture proves how the leaves are glossy and are rounded with toothed edges and a very long tip, just like it said in the species card. *Note that this was a couple feet away from our quadrat, but it is the same kind of plant.* If you choose to go looking for this plant your self (you shouldn't have a problem finding it) know that the leaves are supposed to be between 5-13cm in length.
Photo of my evidence.
In this photo it shows the color of the berry's skin (yellow). It also shows the measurement of the bittersweet berry. This berry is not out of it's skin, so it proves that is is oriental because of the bright yellow color, instead of the orange color like the American Bittersweet. The measurement is approximately one centimeter. These are all identifying qualities of Oriental Bittersweet.
