Sp_Rajshahi

"There are e.g. forms of Hydrocotyle sibthorpioides (widespread in Asia) that look similar to the Australian H. tripartita, however Hydrocotyle has quite many scientifically described species, most unknown in aquaristics. So it's likely that it belongs to an already described species.

For ID it would be best to send an emersed specimen with flowers and fruits to some expert for the genus. For now I'd suggest to call it provisionally Hydrocotyle sp. 'Rajshahi'".- Heiko Muth, Feb 2020.
