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.
