Dear friends We had good discussion in June, 2013 about status of Zehneria scabra in India
https://groups.google.com/forum/#!searchin/indiantreepix/Status$20of$20Zehneria$20scabra$20in$20India/indiantreepix/7ejsnKgMcYI/ReqjsPs4CMAJ I am including some relevant points for Tapas ji and Balakrishnan ji to resolve this issue for us I have been somewhat confused about the status of Zehneria scabra, uploaded by several members including Dinesh ji, Prashant ji, and other members from Kas https://groups.google.com/forum/#!searchin/indiantreepix/Zehneria /indiantreepix/cCGIzB2cd9A/lEwSmgknYegJ https://groups.google.com/forum/#!searchin/indiantreepix/Zehneria /indiantreepix/cCGIzB2cd9A/lEwSmgknYegJ These confusions are often confounded by the absence of author citations. Strange as it may look Zehneria scabra (L.f.) Sond (Swedeish name *flikig pilreva), * and Melothria scabra Naudin (Swedish name *djungelgurka), * are two distinct species, often confused on net, as Melothria is an important species with good looking mini watermelon like fruits, and none look similar to our Kas plants. and as such names Cape zehneria, South African Zehneria won't apply to our Kas plant. My doubts are supported by recent nomenclature update by Renner and Pandey in 2013 They do not list Zehneria scabra for India, and Melothria perpusilla (Blume) Cogn. is cited as synonym of Zehneriaperpusilla (Bl.) Bole and Almeida.......but as per citation this species does not grown in India. The other name often cited as synonym of Melothria perpusilla is correctly Zehneria hookeriana (Wight & Arn) Arn, is endemic to Tamil Nadu This leaves third name Zehneria maysorensis (Wight & Arn.) Arn. found in Tamil Nadu, Karnataka and Maharashtra. Could it be our plant from Kas??? I added this on October 21 Perhaps we may include in our discussion two species described in Fascicles of Flora of India, No 11: Cucurbitaceae, by H. L. Chakravarty Melothria perpusilla (Blume) Cogn. (plant under our discussion for which Zehneria scabra has been used in our uploads) Melothria mucronata (Blume) Cogn. I have gone through the description of two species but find little differences *M. mucronata* having 1-3 cm long petiole, broadly ovate leaves 5-8 cm, as much broad, scabrous, corolla lobes ovate, acute, but important fruits are ovoid-oblong 8-15 mm long, 6-9 mm broad, mucronate at apex. var. *mucronata* with glabrous lower surface, female flower solitary and var. *umbellata* Chakr. with lower surface hairy along nerves, female flowers in axillary umbels........latter is now correctly considered as * Zehneria maysorensis* (Wight & Arn.), Arn, and there is a suggestion that var. mucronata may also belong here. *M. perpusilla* having 2-5 cm long petiole, ovate-cordate leaves 5-9 cm long, 4-7 cm broad, glabrous, corolla lobes ovate-oblong, subacute and fruits globose, 8-10 mm in diam. var. *perpusilla* with acute or mucronate leaf apex and var. *subtruncata *Cogn. with acuminate leaf apex, base subtruncate. var. *perpusilla * is now correctly known as *Zehneria perpusilla (Blume) *Bole & Almeida, but as reported in Renner and Pandey species does not grown in India. var. *subtruncata* Cogn. is now correctly known as *Zehneria bodinieri* (H. Lév.) W.J.de <http://w.j.de/> Wilde & Duyfjes, It must be mentioned that *Zehneria hookeriana* Arn. is endemic to Tamil Nadu and very close to Zehneria bodinieri and I would be happy if some one gives me diagnosis of this species and how to differentiate two . So our collections having gone under Zehneria scabra in our websites may be sought to be segregated into three species:Zehneria maysorensis with beroadly ovate scabrous leaves, ovate corolla lobes and oblong 8-15 mm long fruits, Z. bodinieri with ovate leaves longer than broad, glabrous leaves, ovate-oblong corolla lobes and globose 8-10 mm fruits, and very similar Z. hookeriana. I hope Dinesh ji, Prashant ji who have great collection Western Ghats and South India, and other experts especially Vijayasankar ji, and great expert Prof. Renner should be able to sort this out. I have a feeling that mixed upload by Dinesh ji from Kas and Mahabaleshwar may have both these species, Mahableshwar photograph looking different from Kas one. https://groups.google.com/forum/#!searchin/indiantreepix/Zehneria /indiantreepix/cCGIzB2cd9A/lEwSmgknYegJ Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
