Tripsacum dactyloides, commonly called eastern gamagrass, is a warm-season, sod-forming bunch grass native to the eastern United States. Gamagrass is a distant relative of the corn species (Zea mays) and, like corn, the male part of the plant is located in the upper section of the female part. The joints of the seed-bearing part of the plant break when the plant is developed and each seed-bearing part contains one seed.
