Dear Anurag Ji,

Again I fail to reach a conclusive decision. What I notice in your attached pics are -

• branch muricated, as in T. muricatum, T. leucostaphylum, T. sulcatum
• I am not sure if branches are sulcate
• flowering season doesn't match with muricatum, match with sulcatum, don't have info on leucostaphylum
• leaves in your pics do not have long petiole, whereas herbaria of sulcatum and muricatum show long petioled leaves
• I am not sure if these leaves can be called crenate, as in sulcatum
• Wight Icones T 740 has not been referred to sulcatum
• Icones T 740 is related with muricatum and leucostaphylum
• T 740 has acuminate leaflets, moderately long petiole
• I think leaves and inflorescence rather match with Icones T 28, but branch in that plate is not muricated. T 28 is related to sulcatum as per FBI

Thank you

Regards

Dear Anurag Ji,

No need to hurry, first of anything is your study, you do need to reply any thread right now. I can and will wait until your are done with all your other priorities.

I think it's better to to wait for the mature fruits of this plant if it's in your vicinity.

You can download Icones from http://www.biodiversitylibrary.org/bibliography/92#/summary. Meanwhile attached here related plates for your perusal.

Thank you and best wishes for your upcoming exams.

I would really love to have the Wight Icones. I would certainly make good use of them.

Please give me some time to get back to you sir. It is that time of the year again for me. The last four days have been spent in studying Chemistry for my upcoming end semester exams. I will reply soon.

Thank you so much for your quick reply.

Good evening sir,

I go with Tetrastigma muricatum/Tetrastigma leucostaphylum because the Gamble description (1 and 2) effectively rules out Tetrastigma lanceolarium (although the key puts the species under not or little tuberculate). And the other possible species Tetrastigma sulcatum can be ruled out (if you agree) based on the leaf margin because as you say, they may not be crenate but rather distantly serrate.

Regarding the size of the leaves, I believe I have a very simple answer. I, very unwittingly, picked out a set of NEW AND SMALL LEAVES! Please see the attached photo. Although blurry, the background shows significantly larger leaves than the small leaves in the centre left of the photo.

As for the conundrum between Tetrastigma muricatum/Tetrastigma leucostaphylum:

Character	Tetrastigma muricatum	Tetrastigma leucostaphylum
Branches	Terete, muricate	Angled, tuberculate/muricate
Leaves	Usually 3-foliate, may be pedately 5-foliate (sizes very similar)	Leaves pedately 5-foliate (sizes very similar)
Leaflets	Broadly elliptic	Oblanceolate
Inflorescence	Ferruginous	Ferruginous
Fruit	1cm across (cannot find no. of seeds)	1 cm across, 2-4 seeded

The place is quite accessible with a guide and is only a few hours away from Bangalore. I will update with fruits if possible.

In the meanwhile, please let me know what you think.

Thank you very much.

[surajit koley]

Yes Anurag Ji, perhaps we can skip T. lanceolarium and T. sulcatum.

Since branches are not angled and one or two leaf 3 foliolate it should be T. muricatum, not T. leucostaphylum. Leaves also match with Flora-Karnataka (JCB) herbarium. However, JCB says branches of T. leucostaphyllum is terete and leaves elliptic! Yet, it is closer to T. muricatum, I think.

Thank you

Regards

[Anurag Sharma]

That is quite odd sir. Different books report different shapes.

Thank you sir.

[surajit koley]

Not only the stem character, Anurag Ji, leaves of T. leucostaphylum are broadly elliptic as per JCB, it goes against your description you keyed in your table (comparing both muricatum and leucostaphylum). Fruit sized also differs in JCB.

So, it's a very complicated case, as can be seen in discrepancies in KEY and descriptions across various literature.

Thank you

Regards

surajit

[Anurag Sharma]

Indeed sir.
And also sir, here are those sheets that I referred, one from Coorg flora and the other Hassan flora.

[surajit koley]

Here you have account of T. leucostaphylum from Singapore, Anurag Ji. A bit more elaborate https://floraofsingapore.wordpress.com/2010/08/07/tetrastigma-leucostaphylum/. And also see pictures in http://www.natureloveyou.sg/Tetrastigma%20leucostaphylum/Main.html.

Perhaps you can skip T. l. too!

Thank you

Regards

[D.S Rawat]

Keys from Flora of India vol-5 are attached. Hope these help too.

Thank you very much Rawat sir. Fruits and seeds are so very important to distinguish these species.

Many thanks to Rawat Sir.

Anurag Ji, following Flora of India KEY I would like to try one more time.

We can skip all species after KEY-11b.

We can also skip species no. 8 at KEY-9b

We can also skip species no. 14 at KEY-10a. (we do not have fruits. but distribution is unlikely?)

That leaves us with only two species - T. sulcatum and T. nilagiricum.

It appears to me it is same species as in your other upload - https://groups.google.com/d/msg/indiantreepix/WsS7RH-k8V0/_geQhnWEZhEJ

Thank you

Regards

[Anurag Sharma]

Surajit sir, thank you for your tireless efforts. I also agree with T. sulcatum in both this thread and the other.

I looked in a lot of other district flora and find no mention of Tetrastigma nilagiricum. So that may be ruled out too!

[Anurag Sharma]

Rawat sir, thank you very much for the key!
