Location: Assam Date: 20.9.19 Potamogeton species Seems near P.nodosus. Close to Potamogeton perfoliatus (flowering and fruiting stage is needed for identification) as per reply by … in another thread. To me looks different from Potamogeton nodosus as per images and details herein. Also looks different from Potamogeton perfoliatus as per P. perfoliatus would have all submerged leaves, to me it looks like P. natans Nepali Name : पानी झार Paanee Jhaar Potamogeton perfoliatus (clasping leaf Potamogeton) has leaves arranged clasping the stems and there are no floating leaves, permanently submerged macrophyte. This seems to Potamogeton natans or maybe (excuse me if I am wrong) Aponogeton natans (please look for bulb/onions absence of which rules out Aponogeton). I doubt Aponogeton as they have spoon shaped, rounded floating leaves.
