Amphicarpaea bracteata (hog-peanut or ground bean) is an annual to perennial vine in the legume family, native to woodland, thickets, and moist slopes in eastern North America.[2]
Leaves have three leaflets and are held alternately on twining stems.
Flowers are pink to white and bloom from late summer to autumn. The flowers are either open for cross-pollination or closed and self-pollinating. The closed flowers may be above or below ground.[3]
Seeds from open flowers are held in a flat pod, pointed at both ends, that dries when mature and twists to release the seeds. Seeds from closed flowers are held in round pods with a single seed each. The roots and the cooked seeds from under the ground are edible.[4][5] The seeds which become subterranean from flowers on stolons give it the name peanut.[6]
This plant can be found in eastern North America, as well as further west into the Midwestern region, including Indiana,[6] Illinois,[6] and Wisconsin.[7]

Amphicarpaea bracteata es una especie de planta trepadora anual o perenne perteneciente a la familia de las fabáceas, originaria de los bosques, matorrales y laderas húmedas del este de América del Norte y Asia oriental.[1]
Las hojas tienen tres foliolos y se encuentran alternativamente en tallos entrelazados. Las flores son de color rosa a blanco y florecen desde finales de verano a otoño. Las flores están bien abiertas para la polinización cruzada o cerradas para la auto-polinización. Las flores cerradas pueden estar por encima o por debajo del suelo.[2]
Las semillas de las flores abiertas se encuentran en una vaina plana, que se secan cuando maduran y dan giros para liberar las semillas. Las semillas de las flores cerradas se llevan a cabo en las vainas redondas con una sola semilla cada una. Las raíces y las semillas son comestibles.[3] Las semillas de las flores subterráneas tienen el nombre de maní.
Amphicarpaea bracteata fue descrita por (L.) Fernald y publicado en Rhodora 35(416): 276. 1933.[4]
