Dear All, On the basis of the relevant taxonomic characters discussed by Yazdy Ji & Gurcharan Ji we all can come into a positive conclusion that "The plant in the attached photographs belong to the genus *Solanum sp* and its specific epithet is *Solanum viarum*". I personally thank all of you for taking the tedious effort and well planned techniques to decipher the name of this long discussed plant from West Bengal brought into our notice by Mr. Sibdas Ghosh.
THANKS TO ALL Regards, Tanay Bose.
