Only 2 sp., Centipeda elatinoides (Less.) O.Hoffm. and Centipeda minima (L.) A.Braun & Asch. are found distribution in India and only Centipeda minima (L.) A.Braun & Asch. and its  subsp. Centipeda minima subsp. minima is found in Assam according to one link (PDF) A revision of Centipeda (Asteraceae) its attached screen shot. So, I guess, it could be C. minima or its subsp.
