Where it grows wild

Specimen notes describe it floating free beneath the surface in shallow ponds, lagoons, marshes, canals and roadside ditches, in still or slow water 0.15–2 m deep. The inflorescence is erect and emergent, held by a whorl of 5–6 floats.

Lowland: the main sites are below 80 m, and one Brazilian site is at 869 m.
