A new Piper from the northern Western Ghats and notes on economic potential of Piper section Muldera : Genetic Resources and Crop Evolution 61(6) May 2014 Manoj M. Lekhak, Sharad Kambale, Shrirang Yadav-
(Abstract- Piper dravidii Lekhak, Kambale et S. R. Yadav, a new species from northern Western Ghats is described and illustrated. The names Muldera galeata Miq. [Piper galeatum (Miq.) C. DC.] and M. trichostachya Miq. [Piper trichostachyon (Miq.) C. DC.] are lectotypified. A key for the species of Piper section Muldera Miq. in India has also been provided to facilitate identification. In addition, the significance of species of Piper section Muldera as a candidate in breeding programs of P. nigrum is also discussed).
Keys:
1. Male and female inflorescence pubescent P. trichostachyon
1. Male and female inflorescence glabrous 2
2. Receptacles of male and female flower reniform, distant and recurved P. galeatum
2. Receptacles of male and female flower not reniform, compact and not recurved 3
3. Bract of male receptacle cup-shaped P. relictum
3. Bract of male receptacle obconical P. dravidii

.

P. nigrum belongs to section Eupiper; P. longum and P. hapnium Ham. to section Chavia; and P. cubeba to section Cubeba and are differentiated as under

Section Cubeba: Spikes solitary; fls dioecious; female bract peltate; fruit with a long stalk- P. cubeba belongs here- climbing; stem round; leaves ovate oblong, acuminate, 4-6.5 cm long, 1.5-2 cm long; berry with long stalk.- obviously not my plant. 
Section Eupiper: Spikes solitary; fl dioicios or polgamous; fruit sessile, forming interrupted spikes; bracts and bracteoles adnate to axis- P. nigrum belongs here-Glabrous climbing and rooting plants; leaves coriaceous, ovate oblong; petiole 1.2-4 cm; leaf blade rounded and oblique at base, sometimes cordate; nerves 5-9 (2 pairs near base, more higher); spike variable in length; leaf width upto 2/3 0f length, which again varies; bracts wholly adnate without raised margins- again not our plant.
Section Chavica: Spikes solitary; fls dioiecious; female bracts orbicular, peltate; fruit sessile, in cylindric or globose spikes. P. hapnium and P. longum belong here.

Nomenclatural notes on Piper Linn. (Piperaceae) from India – PRASANTA KUMAR MUKHERJEE- Phytotaxa 289 (2): 188–192, 2017
Abstract More than a century ago, the comprehensive account of the Piperaceae in the Flora of British India by Hooker (1886) listed 45 species of Piper (including Pothomorphe) and ten species of Peperomia from India, Bangladesh, Myanmar, Nepal, Philippines, Sri Lanka as well as the Indonesian islands Java and Sumatra. The genus Piper was treated under six sections, wherein he listed 28 species from present day India. Several years later, C. de Candolle (1923) recognized 95 species of Piper and eight of Peperomia from India, including 41 species of Piper that were new, although they were not described fully until 1925. A number of new species and varieties were also added by Van Heurck & Müller Argoviensis (1871), C. de Candolle (1910, 1912), Gamble (1924), Ravindran et al. (1987), Babu et al. (1993), Gajurel et al. (2001 a & b, 2007), Lekhak et al. (2012), and Mathew et al. (2016). In the meantime, some regional accounts of the genus Piper were also published, including Rahiman & Nair (1987) from Karnataka, Gajurel et al. (2002, 2008) from Arunachal Pradesh, and Das et al. (2010) from Terai Duars, Darjeeling, and Sikkim. Long (1984) published an account of Piperaceae from Bhutan that included records from Sikkim, wherein he suggested some new synonyms. A critical examination of these publications points to their limitations concerning some of the identities and nomenclature.

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.

Nomenclatural notes on Piper (Piperaceae) from India III– PRASANTA KUMAR MUKHERJEE- Phytotaxa Vol 441, No 3 (2020)-
(Abstract- This paper, in continuation of earlier ones (Mukherjee 2017, 2018), deals with the taxonomic studies of the genus Piper Linnaeus (Piperaceae) from India. It includes information on the identity, typification and nomenclature of ten additional species. The results report four new names: Piper courtallensis P. K. Mukh. nom. nov., Piper kurgianum P. K. Mukh. nom.nov, Piper lamarckianum P. K. Mukh. nom. nov., and Piper travancorianum P. K. Mukh. nom. nov. It also deals with the lectotypification and nomenclature of P. argyrophyllum Miquel, P. attenuatum Miquel and P. talbotii C. de Candolle in addition to supersession of previous lectotypification with new ones for P. leptostachyum Miquel and P. peepuloides Roxburgh. Additionally, new synonyms are added for P. obtusistigmum C.de Candolle and P. talbotii C. de Candolle. Identities of P. peepuloides Roxburgh, P. mullesua Don and P. rhytidocarpum J. D. Hooker as distinct species are reasserted. An overall evaluation of their identity and nomenclature including synonyms is included. Necessary explanatory notes are added for each of the species which are dealt alphabetically).

I have updated eFI (efloraofindia) page on Piper

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.

Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.

If someone can provide complete list of Indian species with source references it will be wonderful.

Any comments/ corrections are welcome.


.

Pl. go throughPiper ‎(Piperaceae) page with comparative images of species in efloraofindia. On clicking the link of species, one can check the complete details.

May I request you to pl. go through & point out mistakes, if any. I hope this will aid in identifications in future. If anybody can send images of other species of this genera (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
