Presumed to be Native
SOUTH FLORIDA Cultivated Status:
Although now known in South Florida only from disturbed agricultural fields, in other parts of its range this species grows in mud on the margins of fresh-water ponds (see Adams, 1972); it seems to be an ephemeral annual in South Florida and the Greater Antilles. In the United States, it is most common along the Mississippi drainage. It could easily be an overlooked part of our flora or a recent introduction from other parts of its range.
