Arachis pintoi (Pinto peanut) is a forage plant native to Cerrado vegetation in Brazil. It is native to the valleys of the upper São Francisco and the Jequitinhonha rivers of Minas Gerais. This wild perennial relative of the groundnut or peanut, has been of increasing importance to pasture improvement in the tropics. Its stoloniferous growth habit, subterranean seed production, high forage quality, and acceptability to grazing cattle are of particular value. It is widely used in tropical grazing systems for ruminant livestock.
Pinto peanut is found from sea level up to an altitude of 1400 m. It can grow in areas where annual rainfall is above 1100 mm but does better where it is above 1500 mm. Suitable average annual temperature is between 21 and 22 °C.
