The study has documented the anatomical and molecular variability of the genus, Euphorbia from the southern districts of Kerala. Expeditions across the study area identified six species, namely E. hirta, E. microphylla, E. heterophylla, E. milii, E. tirucalli and E. pulcherrima. Anatomy of stem, root and leaves revealed much variability among species. Among the anatomical characters, leaf characters such as nature and type of stomata, nature of trichomes and stem characters like nature of hypodermis and cortex etc. are of high taxonomic significance. An artificial key for the identification based on anatomical characters was prepared. Molecular characterization using chloroplast loci, matK and nuclear loci, ITS revealed the phylogenetic interrelationships of the species. Nuclear diversity parameters showed an elevated level of diversity for the nuclear loci, ITS when compared to the chloroplast loci. Clustering pattern in the UPGMA dendrogram was mostly in accordance with the subgeneric identity of the species. This work revealed the blue print of anatomical and molecular variations exhibited by Euphorbia in the studied locality.
