Hi, Dr. Hill,
This vine was growing in medium-shade in woods in the SC Fall Line area. The leaves are opposite along the vine. On Nov. 27 when these pictures were taken, the vine’s seed pods were starting to break open. The pods are distinctive in that they are about 6 inches long and very slender (about a 1/4-inch wide). Thin seeds about 1/2-inch long attached to silky parachutes lie end-to-end (slightly overlapping) within the pod. Thank you very much.
Assuming this is a native plant, I would call it Trachelospermum difforme, the climbing dogbane. I’m afraid I don’t know what else it might be. The fruits are a good match but the leaves seem to be a little wider than expected.
