Solanum pandeyii ……………., a new species, is discovered in the Andaman and Nicobar Islands, India. Morphological and molecular analyses suggest that it is closely related to S. violaceum and belongs to the Leptostemonum clade of Solanum (the “spiny” solanums). These two species can be distinguished in habit, vegetative morphology, trichome morphology, indumentums, inflorescence architecture and floral characters. A detailed morphological account, molecular analyses, illustration and preliminary conservation status of the new species have been provided here along with a diagnostic comparison with the closely related species, S. violaceum.
