Here are the keys from Flora of Bhutan as per efi thread:

+ Fruit globose, 4-6mm; pyrenes not winged . . . .. 2. P. foetida

Paederia sp., probably P. lanuginosa?
As per FOC, Paederia lanuginosa Wallich is not distributed in India.
I could find references of only two species in India :
Flora of China says “Fruit globose, 4-7 × 4-7 mm, glabrescent, drying gray to yellow; pyrenes concavo-convex to plano-convex” for Paederia foetida Linnaeus and ‘Fruit broadly ellipsoid to ovoid, somewhat laterally compressed, 6-11 × 4.5-8 mm, glabrescent, drying yellowish gray; pyrenes ovate to elliptic, somewhat flattened, marginally winged’ for Paederia cruddasiana Prain
We have to find the exact keys in Flora of our area.
Pl. also see GBIF specimen 1, specimen 2 and specimen 3, from India.
Can anybody post the keys?
I have photos of this species (Paederia foetida) – from Soraipung in Dihing-Patkai WLS.
It is called Paduri lata or Gendheli lota in Assamese.

I looked for that also but did not find distribution in Assam excepot in POWO.
As such, I am not sure about it !
…, your conclusion of Paederia cruddasiana seems justified. Let us try to find publication on basis of which POWO shows distribution in Assam.
I snapped these from Doldoli Reserve Forest, Karbi Anglong (Assam)
It is called Paduri lata or Gendheli lota in Assamese (Paederia foetida) but fruit does not support.

+ Fruit globose, 4-6mm; pyrenes not winged . . . .. 2. P. foetida
So, it should be Paederia cruddasiana Prain
Yes … Paederia cruddasiana, commonly known as sewervine, is easiest to distinguish from P. foetida when in fruit. The fruit of P. cruddasiana are ellipsoid to ovoid and laterally compressed, with conspicuous wings on the seed margins, while those of P. foetida are subglobose with unwinged seeds.

This vine looks different than what I saw and posted in my earlier upload.
It is growing in a home yard and I am not sure if all leaves I have photographed are of the same plant. The leaves of this particular individual appeared to me different in shape and significantly bigger in size.
Photographed the day before yesterday (4.11.14), in Hooghly District (West Bengal)
Lamina length 14cm avg., petiole 10 cm avg. Leaves have typical unpleasant smell.
The climber is Paederia foetida of Rubiaceae. The leaves are used for making a curry with raw plantain and black pepper to get relieve from arthritis. You do not get the bad smell of the leaves when it is used as curry.
