Extract

Water stargrass (Heteranthera dubia (Jacq.) Mac. M.) is a perennial, rooted, aquatic plant indigenous in the shallow lakes, ponds, and slow rivers of the eastern United States. It thrives in the drainage canals of northeastern Arkansas. This area is basically a reclaimed swamp with intermingled soils ranging from pure sand to heavy clay, and the water table is very close to the surface. Water stargrass reduces the carrying capacity of the drainage ditches, resulting in a rise in the soil water table and in flooded or waterlogged soils. Water stargrass makes its greatest growth in the spring during the season of heaviest load on the drainage canals.
