Field Notes
We were on the main trail in the forest behind Cony. The leaves on the trees were turning a crispy shade of yellow, the beautiful summer flowers were withering, and the air was chilly and damp. Stepping through the wet dirt and gorse layer of lower plants, we found our Oriental Bittersweet almost immediately- and there's no complaint about that! The smell of the rotting trees was subtle, but it was sweetened by the changing autumn leaves. Gazing up at a skinny tall tree, we found a vine-like plant winding up it. One of us took a look at the species card, and analyzed the leaves on the vine and it's thorns. Yup, Oriental Bittersweet. We found it.
