|Current Population Trend:||Unknown|
|Habitat and Ecology:|
The species typically grows on seasonally inundated muddy depressions the drawdown zones of ponds, lakes and reservoirs, and on islands, bars and the margins of rivers. Competition with perennial plants, particularly grasses, is suppressed either naturally such as by seasonal variation in water levels or anthropogenic actions such as poaching by cattle.
