*Hydrangea* sp. is an unidentified climbing Hydrangeaceae plant with slender brown stems and opposite green leaves. The foliage is small, elliptic, lightly textured, and held in spaced pairs along the vine. Some *Hydrangea* species grow as root-climbing lianas rather than shrubs, with adventitious roots forming along the stems when they contact bark, moss, or other moist surfaces.
