I have found your document, https://extension.umd.edu/hgic/topics/chinese-and-japanese-wisteria, very useful and have referred many people to it to distinguish between the two invasive species. In it, you state that, "Vines of Chinese wisteria grow in a counter-clockwise direction (as do those of our native wisteria). Japanese wisteria vines grow clockwise." So, if I'm understanding it correctly, the plant in the image twining around the pine, UGA2188068, is a Chinese wisteria, correct, since it appears to be doing so counter-clockwise? It would be helpful to identify it, just so people have an example of growth form.

You are correct. The image (UGA2188068) shows a Chinese wisteria vine. We will clarify this in the photo caption. Thank you for the suggestion.
