SK1105 24 APR-2018 : 9 posts by 3 authors. Attachments (8) Location: Godawari, Nepal Date: 18 April 2018 Altitude: 5000 ft. Habit: Wild I am not able to conclude anything with these photographs. Looks close to Persicaria caespitosa, but not sure. I think your guess matching. The Plant List says no synonym whereas the Catalogue of life says some synonyms. Request for the final validation. Thanks, ... for sharing the links. I would suggest you dissect the specimen if you have one. Persicaria is a complicated genus and hybridization is also frequent. Your plant is close to P. caespitosa, but I cannot confirm the ID based on the given pictures. References:
