The new taxon Nymphoides krishnakesara var. bispinosa, collected from the ponds in the lateritic plateau of northern Kerala, India is described and illustrated. It shows close similarity with Nymphoides krishnakesara var. krishnakesara but can easily be identified by its pinkish tinged veins on the floating leaves and two long stout spines on the seeds.
