Thanks, Paradesi ji.

Looks different from images at Operculina turpethum

I think it may be Merremia umbellata

Pl. check.

On further rechecking many genera, I think it is Merremia umbellata only. Pl. check the variations herein.

Do you have any more photographs? This is no Operculina turpethum.

Check Aniseia martinicensis (Jacq.) Choisy - http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:30070865-2

[surajit koley]

btw, it is Ipomoea uniflora of FBI.

Thank you

If stem has wing like structure this could be O.turpethum

Aniseia martinicensis is wrong ID. None of the flowers shows "sepals decurrent on the peduncle."

I doubt it can be Operculina turpethum either - flower buds are very similar, but, in the uploaded pic 1) leaves are entirely different (though leaves are variable in convolvulaceae) (2) no wing can be seen on terete stem (3) anthers are not twisted!

I refrain myself from commenting on Merremia umbellata.

I will get back if I find a suitable alternative.

Thank you

With regards

I withdraw my doubt  of the ID Operculina turpethum - as per FBI, (1) leaves can be oblong (2) stem can be nearly round. AND maybe anthers would twist later.

So, please go ahead with Operculina turpethum, I couldn't connect it with any other FBI member.

Thank you

Hi, Surajit ji,

What do you think of Merremia umbellata ?

Sir ji, I think in all M. umbellata uploads in eFI (1) leaf base is either cordate or sagittate (here none sagittate, mostly rounded) (2) corolla tube is a it narrower than this one (may be my illusion) and (3) there are pits (?) inside the base of corolla tube which can be seen in my pictures (3rd photo) too - https://groups.google.com/g/indiantreepix/c/u0GYGn-2UCo/m/J_vVOSMFtCoJ.

GBIF has specimen with oblong leaf, from other other countries 

Certainly, this upload has more than one odds against it to be Operculina turpethum, yet I think it is the closest.

Thank you
