Dear Anurag Ji,

I can clearly see the fruits of this species, those fruits can't be called
smooth and Roxburgh was correct. I said Roxburgh would know his species
better than any other source.

I copy here a few words from "Revision of the Genus *Aponogeton* / H. W. E.
VAN BRUGGEN" :-

   - ovules 4-8; tepals white, pink, or violet ... fruit with very long
   (1mm) terminal beak = *natans*
   - ovules 2 (seldom1); ................... fruit smooth = *crispus*
   - do ...............................     fruit mostly with irregular
   excrescences, seldom smooth.... = *echinatus*

The differences between the 2nd and 3rd above lie in tuber, leaf,
inflorescence, tepal, filament, fruit and plumule.

So, you can boldly go ahead with the ID *A. echinatus* Roxb. with your
species, no matter eFI admit or not.

Thank you
Regards
