Please validate or correct

I had originally classified this wildflower as a Pinos Altos Mountain Bean Phaseolus Parvulus. But now I am unable to verify that. If that is a correct ID then what is this plant doing in south central Tenessee.

Image HAS NOT been post processed other than to resize to the internet. so the only critique I am looking for is the identification. Please help to validate or correct me. Thank you.

Was this a viny plant? If so, it could be Phaseolus polystachios, also known as the thicket bean or wild kidney bean, which is found in Tennessee.

Yes, it was a bit viney. Thanks for the info,
