Groundnut - Origin And Botany

Groundnut is found wild in West Africa, but rarely so. It has been cultivated throughout tropical Africa for many centuries. It was taken at an early date to Madagascar, probably by Arabs. It reached Brazil and Surinam early in the 17th century and was later taken to the Philippines and Indonesia.

Groundnut is an annual herb with creeping much branched stems, rooting at nodes and very short internodes thus giving a bunchy appearance to the plant.
Leaves are pinnately trifoliate, petiole long, erect, grooved and thickened at base.

Inflorescence axillary, 1-3 flowered, but usually 1 flowered, peduncle short and thick, pedicel short flowers small calyx glabrous with upper lobes connate, pale yellow, wings oblong obvate, same length as keel, which is almost straight, stamen diadelphous, uniform with free auxiliary stamen, style short, bent, hairy along inner surface, stigma small, lateral.
