Taxonomic Study on the Wild Species of Genus Solanum L in the Southern Western Ghats of Tamil Nadu

An excursion flora of Solanum (Solanaceae), distributed in Southern Western Ghats ecoregions of Tamil Nadu. The work illustrated to study of complete morphological features of each species, distribution, nomenclature, synonyms, vernacular name, common name, flowering season, Geographical locations, Ecological status, GPS co-ordinate, elevation, habitat, enthnomedicinal uses, formulations and the taxonomic relationships between the studied species is represented by the cluster analysis. The Morphological characters indicated highly significant role in the identification of the species. Based on the detailed survey, two species was native species and remaining three species were invasive plants. The morphological variations measured by Eluidean distance process and phonogram were constructed. The phenogram showed that the studied species of genus Solanum can simply be divided into two groups that are Melongena and Solanum. The phylogram was represented by using parsimony analysis of the morphological data. The phylogram showed that most of the species are distributed all over the study area. Therefore the goal of the present study was to identify distinctive morphological feature on both of Phylogram, and Phenogram. The results was represented showed great similarity between S.virgianianum and S. incanum suggesting that the two species can be considered as one species with two subspecies or varieties.
