Common name: Pinto Peanut
Botanical name: Arachis pintoi    Family: Fabaceae (Pea family)

Pinto peanut is a perennial tropical legume useful for pasture, ground cover and ornament. It is a runner forming perennial creeping legume that can reach 20-50 cm in height and form dense swards. It is strongly tap-rooted and has many secondary nodulated roots. The stems are initially prostrate and then become ascendant. The leaves are tetrafoliolate. The leaflets are oblong-obovate to obovate in shape, 4.5 cm long x 3.5 cm broad, hairless and darker green at their upper side and velvet-hairy at their lower one. The dlowers are yellow, borne on short in leaf-axils racemes and very similar to groundnut flowers but smaller. Like groundnut, once pollinated, the flower stalks elongate and grow down into the soil, penetrating the soil up to a depth of about 7 cm. The fruit is a at branch-ends underground, one-seeded pod, 1-1.5 cm long and 6-8 mm in diameter. It can be found in the upper 10 cm of the soil. Pinto Peanut is native to Brazil.
