                                Although many people assume that a well-known crop like corn is the largest, a far less common grain, Job's Tears (Coix lacryma-jobi), holds the title for largest cereal grain. This large, tear-shaped grain is native to Southeast Asia and has been cultivated for millennia for both food and medicinal purposes.
