Heteranthera dubia

Water stargrass is grass-like with thin branchi8ng dark-green stems and alternate leaves with no prominent midvein. Water stargrass can grow up to 6 feet long and can form floating colonies. Flowers rise above the surface and are bright yellow, \star-shaped, with 6 narrow petals. Water stargrass reproduces from seeds and through fragmentation.

Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. These invertebrates in turn are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food (called "detritus") for many aquatic invertebrates. Water stargrass is consumed by ducks and wading birds but is not known as an important food item.
