Assuming this is a climber, 5 foliolate pedate leaves, glabrous nature, corky warts o tubercles, short and compact cymes suggest it can be Vitis lanceolaria Roxb, FBI i. 660.

Thank you

How about Tetrastigma species ?   Not sure.  Need to compare the characters.

[surajit koley]

Yes, I agree with you, Mahadeswara Ji, but there is a problem with accepted name -

• I think it is Vitis lanceolaria Roxb. of FBI, the accepted name of which, as per TPL, is Tetrastigma lanceolarium (Roxb.) Planch. But at the same time TPL gives a note - "A cross-taxon basionym link was ignored while processing this record, see Cissus lanceolaria Roxb..". I don't know what does it mean.
• Our group identifies Cissus lanceolaria Roxb. with Tetrastigma leucostaphylum (Dennst.) Alston ex Mabb.

That's why I suggested the name i found in Flora of British India.

Thank you

Regards

[J.M. Garg]

Thanks, Surajit ji,

Accepted name & synonyms as given in efi is based on GRIN (2014) & Flora of Eastern Ghats: Hill Ranges of South East India, Volume 1 By T. Pullaiah, D. Muralidhara Rao, K. Sri Ramamurthy (2003- Description & Keys)

[surajit koley]

Thanks Garg Sir, in that case it may not be Vitis (Cissus) lanceolaria Roxb,

Thank you

Cayratia pedata (Lam.) Gagnep.

[Samir Mehta]

Cayratia sp.
Have reservation about Cayratia pedata as plant not hairy / pubescent. Further, berry seems globose and not sub-globose / compressed at both ends.
Pls consider C. tenuifolia or another from local flora.

Samir Mehta

The species in question is  Tetrastigma species , as suggested by me earlier. T. leucostaphylum ?  Please provide the correct citation.

[Anurag Sharma]

Thank you very much sir. I will take it as a Tetrastigma sp.

[surajit koley]

Anurag Ji,

In FBI the distribution of Vitis rumicisperma Laws. is restricted to Sikkim Himalaya, Khasia Mts. FBI thinks it is also allied to V. lanceolaria. FBI says it has leaves usually pedately 5-foliolate, rarelt 3-foliolate; branches with corky wart or tubercles; fruit the size of large currant; seed broadly triangular-obcordate.

The book Garg Sir mentioned earlier informs it is present in the South too, as Tetrastigma rumicisperma (Laws.) Planch.

Please check probability.

Thank you

Anurag Ji,

Flora of Karmataka thinks (1) Tetrastigma lanceolarium is accepted name of Cissus/Vitis lanceolaria and (2) T. leucostaphylum is accepted name of Tetrastigma muricatum (Wight & Arn) Gamble.

KEY and description of the above two species can be found in the same site - http://florakarnataka.ces.iisc.ernet.in/hjcb2/herbsheet.php?id=4504&cat=1

It is ironical that the fruit size of T. leucostaphyllum given in the above site goes against the book Garg Sir mentioned earlier. It is further more ironical that our group recognize the second one above is a different taxon - https://sites.google.com/site/efloraofindia/species/m---z/v/vitaceae/tetrastigma/tetrastigma-muricatum

Certainly what the above book says about the fruit (triangula-obcordate) of Tetrastigma rumicisperma is wrong. The fruit of this species (T. rum.) will be same as T. lanceolarium but  smaller (check FoC); and the plant will be same as T. lanceolarium.

All the above confusion, I think, lies in a single Wallich collection - Wall. cat. 6013. and entries in FBI.

So, forget about all experts, books, sites. Take a tip from this non-botanist-expert one, i.e. myself!

Your plant is Tetrastigma leucostaphylum as per fruit size (more than 1.2 cm?) mentioned in your Flora of Karnataka site.

Thank you

Regards

Excellent Surajiy ji.   Great  in-depth study .   Who said you are a non botanist ?  You are  not only a botanist but a great taxonomist.

[surajit koley]

Thank you very much Sir. Now, everything depends on mature fruit size and backed by seed picture.

 Surajit ji for the efforts you take to dissect the available resources.

Thank you very much.

[surajit koley]

Thank you very much Dinesh Ji. I really spent much time on recent vitaceae uploads. Thank you for recognizing.

[Anurag Sharma]

I do take a Tetrastigma leucostaphylum then sir. Thank you very much.

Anurag Ji,

Please don't take my words. You do express your view freely, in the process I would learn something. I think there is less probability of this plant to be T. sulcata (Laws.) Gamble, because leaves are crenate in that species, as per both of the resources we have seen earlier. This species has characters of Vitris lanceolaria Roxb. Since lanceolaria si now divided in to two taxa, and I assume fruits are likely to grow a little more I think it has possibility to be T. leucostaphylum.

Thank you

Regards

Anurag Ji,

I didn't receive the Rawat Ji's mail providing Flora of India KEY in the other thread. Under the changed scenario we need to reassess both the threads. We wasted many many hours chasing wild goose. The fruit size and murication in Flora of India KEY is quite opposite to what we found in http://florakarnataka.ces.iisc.ernet.in/hjcb2/img/pdf/Tetrastigma%20leucostaphylum/184.pdf.jpg.

We would start at KEY 1b of Flora of India and move towards : 1b -> 8 -> we will stop at 8a.

Because I think 

(a) these berries are likely to grow more than 1 cm. 

(b) the branchlets are smooth in T. leucostaphylum 

(c) leaflet margins are revolute in T. nilagiricum 

(d) berries are turbinate globose in T. rumiscispermum.

So, it should be T. sulcatum. What do you think?

Thank you

Regards

surajit

 

[Anurag Sharma]

I agree sir. Thank you!

Now that both this thread and the other have been narrowed down to T. sulcatum, I will club the two together so that it can be reffered to in the future all in one place. I will combine the information from both the threads too.

Thank you once again.

[surajit koley]

Thank you Anurag Ji and Rawat Sir.

Regards

surajit
