Abstract
Solanum is one of the largest and hyper diverse genera of the family Solanaceae. In Pakistan Solanum is represented by 15 species, of which 11 species have the medicinal properties. Taxonomically this is a complex genus because of the presence of number of hybrid and controversial taxonomic status of S. nigrum complex. In the present study numerical techniques were utilized to evaluate the taxonomic status of the genus Solanum. Cluster analysis was employed to work out the relationship among the taxa of the genus Solanum. The Euclidean distance measured similarity matrix and a dendrogram was constructed by using the complete linkage method. This analysis showed that all the species of genus Solanum can easily be divided into two groups at hundred percentage linkage distance. Co-relation of quantitative characters showed that floral characters had highly significant relationship with the stem characters, these characters plays a significant role in the identification of the species of the genus Solanum.
