Rotala rotundifolia, the dwarf rotala,[1] is a plant species often confused with Rotala indica.[citation needed] It is sold in the aquarium trade, but is of uncertain status.

It is a common weed in rice paddies and wet places in India, China, Taiwan, Thailand, Laos, and Vietnam, and has been introduced to the United States.

## Description

[edit]

The emersed form has rounded leaves, while submerged leaves are narrow and lanceolate. Form and color may vary with light and environmental conditions. Under strong light, the leaves can become almost wine red. It has pale pink flowers. This plant can be differentiated from the closely related R. indica by the differences in the two species' inflorescences. R. rotundifolia bears groups of terminal inflorescence, while R. indica has solitary flowers on the axis of the leaves.[citation needed]

## Cultivation

[edit]

A common aquarium plant, it is undemanding, but requires light to thrive. R. rotundifolia can withstand relatively cool temperatures. Losing its lower leaves usually means it is not receiving enough light. It can be grown emersed in shallow water, where it will flower. It is propagated by cuttings. [2]
