<p class="MsoNormal">Hi. Here along the Maury River in Rockbridge County, VA, a friend of mine pointed out a vine to me, indicating that she thought it could be air potato. I have been fortunate enough to never deal with air potato vines, and am not familiar
with it nor its ilk. In examining it and noting the purple area on the stem, I wonder if it is instead winged yam. Neither appears on the MAIPC invasive plant list (<a href="https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.invasive.org%2Fmaweeds.cfm&data=02%7C01%7Crod.simmons%40alexandriava.gov%7Ca3df1ecd7b254e70b45a08d71456381f%7Cfeaa9b3143754aeeadccc76ad32a890b%7C0%7C1%7C637000232871095922&sdata=eyHq1Ch3j3KQDA4EKvLSrIJ8HrND%2FjF0LVHCV09FXoU%3D&reserved=0">https://www.invasive.org/maweeds.cfm</a>),
but I see that both plants are invasive in regions south of here. They would therefore be a fitting addition to my Invasive Plant Arboretum, but I would really rather not have yet another plant to remove. <o:p></o:p></p>

<p class="MsoNormal">Would you dear people please help me determine that this plant is not an invasive but rather a native plant that I can leave alone?<o:p></o:p></p>
