Thanks Sir for taking care. Anurag Ji's point is that fruits here are echinate, so it should be *A. echinatum* Roxb. Now, if the current accepted name of *A. echinatum* Roxb. is *A. natans* then it is the same.
The problem is old lit consider all three different taxa. Another problem is nowhere I could find that *A. natans* can have echinate fruit/capsule. Here is a paper from Pakistan http://www.pakbs.org/pjbot/PDFs/40(1)/PJB40(1)001.pdf And here is the protologue - http://biodiversitylibrary.org/page/16802027#page/16/mode/1up On Thu, May 21, 2015 at 3:11 PM, Gurcharan Singh <[email protected]> wrote: > While doing ecology practicals nearly 48 years back in Kashmir, and > luckily I still remember, we had a few clear cut species of Potamogeton: P. > pectinatus with finely dissected leaves, P. lucens with semitransparent > leaves, P. natans with thick flat shining floating leaves and P. crispus > with wavy (crisped) leaves.
