The genus Rotala L., is represented by about 44 species and primarily distributed in tropical and subtropical regions. In India, the genus has represented by 66% of the globally known species and among that 83% are remarkably endemics which show its evolutionary significance. The study on this genus led to discuss a novelty to science, which has been collected from the lateritic plateau of northern Kerala, India. The species is similar to R. densiflora (Roth ex Roemer & Schultes) and R. malampuzhensis R.V. Nair ex C.D.K.Cook, but differs from the former by having smaller habit (size), aristate bracteoles, clawed petals, and presence of nectar glands etc., and from the latter by its habit, trimerous flowers, shorter or absence of calyx appendage.
