Dear Saroj Ji, Sorry for my previous statement ''Persicaria assamica is characterized by having a spicate inflorescence, which is not the case here''. Actually, the inflorescence is spicate here. Don't know how I overlooked it. Anyway, found the type sheet of P. assamicum here (http://sweetgum.nybg.org/science/vh/specimen_details.php?irn=155978). And I am not much convinced with my previous ID i.e. P. assamicum.
My another guess would be P. hydropiper, a polymorphic species, known to have many varieties. But before finalizing it, try to dissect the plant (If the specimen is available). Nut characteristic is also an important character in Persicaria. Other members may add.
