To me, looks like Argyreia sericea ……… what about hairs ?

First is to rule out Argyreia argentea which is endemic to NE states and Sikkim, Bhutan, Himalayas.
What I considered is bracts …….. proximal bracts are bigger and leaf-like which favours A. sericea. Should be further confirmed by presence of silky hairs all over. 

Description in this link supports A. hookeri

Confirmed here
researchgate and here flowersofindia
Please ignore previous two comments. 

Thanks, … and …, for the id as Argyreia hookeri C.B.Clarke.
However, it is very difficult to clearly see the bracts/ sepals, which are very important for id.
May I request …, to pl. post larger mage showing these clearly.
As it is, to me also appears close to as per GBIF
However, these can be confirmed only after seeing detailed images.
Images in FOI are not of this species. These were identified as Argyreia pilosa Wight & Arn. in thread Argyreia involucrata (Convolvulaceae) (corrected now in FOI).
I request … to pl. correct in FOI.

Please discuss. Argyreia hookeri, I think. Common in and around Aizawl city (Durtlang, Lengpui, etc.). Altitude : 350 – 1,300 m.

I think yes.

Ipomoea for ID : 230111 : AK-3: Taken at Munnar, Kerala on the 21st of October,2008. Growing wild by the roadside.

– The 2nd photo contains much more detail that the 1st photo.

The plant seems to be consistent with some type of argyreia but I could not say for certain but i will mention some noteworthy characteristics that i see
1) the leaves are cordate
2) there stems have a fine whitish pubescence that is typical for Argyreia type species
3) there is hair visible on the ribs extending the entire length of the corolla
4) the secondary bracts at the base of the peduncle and pedicels are quite different in structure as compared to the sepals

To me appears close to Argyreia hookeri C. B. Clarke as per this image.

Its Argyreia populnifolia but have to confirm by observing its bracts and bravteoles.

It might be Argyreia hookeri

Attaching a collage of Carpenter bee visiting flowers of Argyreia nervosa.
Plant is not of Argyreia nervosa as per comparative images at Argyreia
Pl. post the original image showing the bracts/ sepals.

Argyreia sp. I think

I  guessed so … but it would be difficult without flower image to ID.

May be Argyreia hookeri C. B. Clarke basing on the inflorescence, sepal and bracts shape along with those of the leaf.

You may be right … since leaf pattern looks matching. However, no images in net for comparison of fruits.

.

Argyreia roxburghii in FOI:
Images of Argyreia roxburghii in FOI by … are not correct as per GBIF specimens- one and two

It has been identified as Argyreia hookeri C. B. Clarke as per discussions herein.
Pl. correct.

Corrected on the site now.
