Southern Western Ghats (Endemic)
Piper hapnium an endangered and endemic Piper of the Western Ghats.
Thanks for posting this Piper.
Some general questions about this pepper: Is this used by people and if so how-medicine/food as a spice etc.
Which part of Western Ghats is this found?
Are other Pipers-for ex. Piper longum found in the same area as this Piper?
How do we identify this Piper if we come across it in the field?
Would appreciate if you could clarify these questions.
It seems my mail about Piper longum has stirred … The only thing I can say now that my photograph matches with posted earlier on Indiantreepix, but is different from link on the left (Mother Herbs). My plant and that posted earlier on Indiantreepix have broader leaves with clasping base, whereas Mother Herbs….. plant seems to have longer, narrower leaves without clasping base, and a very short petiole. I will try to collect more information when I go to the University tomorrow.
I am should I say excited by the enthusiasm of the accomplished members of the group. As everyone in the group knows that I am a novice in the field, I am thrilled like a schoolboy who is attending the first few days of college.
Your description of the breadth of the leaves and the petiole intrigues me. I have seen piper nigrum vines with broader leaves (Paniyur variety), and narrow leaves like what the local call by different names like otte thiri etc. Longer leaves of varieties like balankotta.
However they are all piper nigrum are they not? Please enlighten me.
When I wrote about P. longum, there were two things in mind:
Here are the names of Piper species in Marathi…
‘Piper nigrum’ – ‘काळे मिरे’ ‘Kale Mire’
‘Piper trioicium’ – पोकळ मिरे’ ‘Pokal Mire’
‘Piper longum’ – पिंपळी’ ‘Pimpali’
‘Piper retrofractum’ – मोठी पिंपळी’ ‘Mothi Pimpali’
‘Piper betle’ – ‘पानवेल’ ‘Panvel’
This could be Dioscorea or Tinospora. I imagine if any one can id from this condition. May be by digging out the roots/tuber!!
Please check Piper longum of Piperaceae as well.

Nomenclatural notes on Piper Linn. (Piperaceae) from India II PRASANTA KUMAR MUKHERJEE Phytotaxa 338 (1): 017–032 (2018) (Abstract- In continuation of the taxonomic study of the genus Piper from India (Mukherjee, 2017), eighty-four Piper names, reported from India, are considered here for their typification, identity, and nomenclature. The scrutiny led to the recognition of twenty-four species. Thirty-five synonyms are proposed as new ones out of sixty-one treated here. Lectotypes are designated for almost all the species recognised here together with their synonyms or basionyms. Holotypes are mentioned when applicable. Of particular mention are P. hookeri and P. sylvaticum with confused identities and lacking proper typification. Corrections are suggested to earlier lectotypifications for P. hymenophyllum and P. rhytidocarpum. Extension of distribution to India from Myanmar are recorded for three species: P. acutistigmum, P. leptostachyum and P. pothoides.)
