* **Fungal Infection:**
* Small, circular spots with dark red centers can be seen on many of the leaves.
* These spots are likely caused by a fungal infection such as Deutero fungus (Neocercosporidium smilacis or Cercospora smilacis).
* **Background:**
* The background is filled with the stems and leaves of other greenbrier plants.
