I only give you some tips –

Thank you

Tetrastigma species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available)

Thank you for your opinion and advise, …

Vitaceae is a complex family!

While ferruginous-tomentose inflorescence is a feature of T. leustaphylumnearly entire leaves are feature of T. gambleiMoreover, young fruits of the later are said to be yellow as per book link. the hint of which can be seen at the base of berries in pic DSC_0390. Who knows those berries won’t turn yellow entirely and then red when ripe! Again sizes are essential. Of course flower-fruiting time doesn’t tally, but how much these species were studied? And how correct are the resources available in the net?



Please tell me your views on alternative(s) which I am ready to accept happily.

Meanwhile check one of your modified pic.

Sir, you have done the bulk of the job and provided me with keys, descriptions and even my photo from a different perspective! I agree with you.

I also agree with you on another matter- the lack of exact measurements. <.8 cm across in T. gamblei and >1.2 cm across in T. leucostaphylum. Lesson learnt. Will make sure to click with a scale henceforth.

Also, I do wonder what the colour of berries in young T. leucostaphylum is.  

…, if you search KEW herbaria you will find it very interesting how closely these plants, lanceolaria and allied species (muricata, sulcata, nilagirica etc) look like.

In FBI Vitis lanceoalria and Vitis muricata are synonymous. In FI V. lancelolaria  leaves are remotely sharply serrulate, texture rather fleshy.,,, flowers small yellow. FI is silent on fruits. Cissus faminea Roxb. has “a little crenulate” leaflets… so, I am in total darkness.
In Wight’s illustration leaves of muricata are serrate or serrulate.
I agree that this complex of Vitis lanceolaria is very complicated and there is 1:1 chance of wrong ID. Please check your local flora if they have more elaborate description.

I will also go with T. gamblei Shetty & Singh as suggested by … and as per keys in Flora of India at Keys as per efi thread and as per comparative images at Tetrastigma
