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 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.
