Dear Garg Ji, After a bit of search I came to known that there is a species of Commelina which has similar leaf, floral & stem morphology to that of your photo and also prefers to grown in the marshy condition. Commelina cyanea has been called "scurvy weed" as it was used by early European settlers to avoid or alleviate scurvy. It is a weak trailing perennial herb, generally prostrate or nearly so, with fleshy stems growing up to 1-2 metres in length. It superficially resembles the common introduced weed, wandering jew (Trandescantia fluminensis; syn T.albiflora), but differs in that the lance-shaped (lanceolate) leaves are narrower and it has bright blue (rather than white) flowers occurring over the summer and early autumn period. Scurvy weed tends to grow rapidly in warm and/or wet weather and die back in the cooler, dryer months. This plant has been recorded from wetlands of India and specialy you will be happy to know that West Bengal is considered as one of it's favourable regions. In the link below you will find a complete disertation thesis submitted by a forestry student of Bangladesh which was later published supports by thinking,
