Rotala rotundifolia has very different emersed and submerged growth
patterns. That probably explains the differences in the pictures.
Emersed leaves are round and green, submerged leaves have more red,
and are elongated. Emersed leaves usually are four per node, submerged
leaves can number anywhere between two and four per node.

Cardamine lyrata? Hydrocotyle leucocephala? However, both these
plants are larger than the plant you describe.
