Ecology

A diminutive rhizomatous perennial growing on firm estuarine mud by tidal rivers, and in tidal pans in brackish grazing marshes. It occurs close to the upper limit of tidal influence, avoiding strongly saline areas. It reproduces vegetatively by turions, and by seed, but flowering and fruiting is very poor in many localities. Lowland.
