Peanut

Peanut

Peanut Arachis hypogaea is extensively cultivated for food and oil. The flower is yellow and the upper petal is much longer than the others. The fruit grows in a most unusual way developing a long "peg" that grows down into the soil to bury the ovary underground. There the seeds develop in small pods while the fruit absorbs nutrients directly from the soil. [CH] {FW}
