Ok we can speculate on this all day long but I just love to research and this a forum. Anyhow I found this document about a road project in Himachal Pradesh. It runs between two towns named Ghumarwin elevation 790 (spelled Gumarwin in some places in the document) and Saraghat elevation 950. ON page 46 it list plant species along the road. A Musa species is listed. Evidently 4 plants along the route. At the Hill Banana web site it list a market where these bananas were being sold named Rampur. Well Ramptur elevation 2500 is just a little west of this location.
