Hog Peanut

Amphicarpa bracteata

This plant is vine-like, and can usually be found twining its way around moist thickets, especially around streams and ponds. Racemes of white or pink flowers are produced from the leaf axils in August. The leaves of this common plant are also distinctive -- 3 ovate leaflets that are rounded near the base.
 

And from Western Pa.

A delicate, downy, twining vine without tendrils. The leaves have 3 ovate, pointed leaflets, only the middle one stalked. The 2-lipped, pink 1/2" flowers are in racemes. The curved seedpods contain 3 or 4 seeds. Flowers near the base or underground lack petals and have fleshy, 1-seeded pods. Blooms August, September in moist woods and wood borders.

Hogs rooting for the underground seedpods gave rise to the name "Hog-peanut".
