The genus Solanum L. is the largest genus in Solanaceae family, with around 1250 species worldwide. The present study aims to characterize the morphological and anatomical account of six wild species of Solanum namely, S. nigrum L., S. americanum Mill., S. viarum Dunal, S. torvum Sw., S. indicum L., and S. aethiopicum L. collected from the district. Variation in stomatal index and stomatal density were observed among the species. The stomatal index varies from 42.85% in S. viarum Dunal to 35.29% in S. americanum Mill. Similarly, stomatal density varies from 71.33mm2 in S. nigrum L. to 40.76mm2 in S. torvum Sw. and S. viarum Dunal respectively. Considering 47 morphological traits and 6 OTUs), a dendrogram was constructed by using a cluster analysis software SPSS 26.0 version which shows S. nigrum L. and S. americanum Mill. as the most similar having standard Euclidean distance 6 and S. nigrum L. and S. viarum Dunal as the least similar having standard Euclidean distance 171. Ethnobotanically, out of the six studied species five species S. nigrum L., S. americanum Mill., S. torvum Sw., S. indicum L. and S. aethiopicum L. were used as vegetables. All the six Solanum species are also used to treat problems such as fever, cold and cough, skin diseases, stomach aches, asthma, gastric, burns etc.
