-… may be another species of Argyreia… for A. nervosa, the unmistakable fluffy white (bracts or) calyx is missing … http://www.flickr.com/photos/dinesh_valke/2852873593/

– another option is A hookeri

To me it appears closer to Argyreia hirsuta Wight & Arn. as per comparative images at ‎Argyreia
Images of Argyreia hookeri at look different:
Thanks a lot, … Than the images by … at Argyreia for identification 050813MK01 will also be of Argyreia pilosa. Pl. confirm.
Also the images by … at ANMAR27/47 Convolvulaceae for identification will be of some other species ? Pl. correct.
Posted images seems to match with type images of Argyreia pilosa at http://convolvulaceae.myspecies.info/content/argyreia-pilosa-6 as identified by …
But type image given in GBIF at ville-ge & at http://convolvulaceae.myspecies.info/content/argyreia-pilosa-0 looks different.
May I request someone to help in this matter. 

It is not Argyreia pilosa; reasons the young stems/ branchlets are not reddish hirsute; leaf apex is not acute;  flowers not in capitate heads etc.,

To me appears more closer to images at Argyreia hirsuta Wight & Arn. as per comparative images at Argyreia‎

Yes it appears close to Argyeia hirsuta; sepals should be ovate

I think it may be Argyreia pilosa as per images herein and as per discussions another thread.
Also does not match with high resolution specimen of Argyreia hirsuta at the following:
On further examination, I feel it is more closer to Argyreia pomacea Choisy as per high resolution specimens at GBIF: one, two, three, four and five
