I found this information from Aquatic Plant Central helpful: 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 inflorescences while R. indica has solitary flowers on the axis of the leaves or short axillary spikes.
