Piper longum L. ??

Looks different from images at Piper longum

Checked all sp. Piper plus new one P. rhytidocarpum Hook. f. listed in Nepal
and I guess it matches with Piper nigrum L. Leaf looks a complete match.

Sir it could be P. mullesua. But needs more representation.

But fruiting bunch looks completely different according to Piper mullesua Buch.-Ham. ex D. Don and my earlier posts on Piper mullesua Buch.-Ham. ex D. Don !

Though it has got no distribution in Nepal, could it be Piper hymenophyllum Miq. ??

Thanks, …, for high resolution detailed images.
Yes, appears close to images at Piper hymenophyllum (S. India, Sri Lanka, Assam to Indo-China: Assam, India, Laos, Sri Lanka, Vietnam as per POWO)
But only experts can decide in view of this complicated genus.
