I could not see the images. But if these are same as at!topic/indiantreepix/ygG-6C43G8c
Than these have been identified as Argyreia pilosa  as per details herein.

yes sir it is Argyreia pilosa only

This page should not have been there. I have removed it now.

Mistake here i want to tell here given specimen by me is of Argyreia pilosa will post it again wrongly identified by me as argyreia involucrata

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

I think it is 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:

Yes I agree with …; It is Argyreia pilosa only

On further examination, to me also appears closer to high resolution specimens in GBIF of Argyreia involucrata C.B.Clarke (it lists two varieties herein- inaequalis and involucrata) as below:

Argyreia pilosa
Ajara, Kolhapur , Maharashtra, 2017 October
Thanks to, Pramod lawand for helping in Identification

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

No sir this is not hirsuta at all. Argyreia pilosa Confirmed by …

Pl. check images of this species at /species/a—l/cl/convolvulaceae/argyreia/argyreia-pilosa 

Also check herbarium specimen of this species in gbif on line.

Looks different from type images of Argyeia pilosa at gbif as given below:

To me it appears to be Argyreia pilosa only;

Thanks, … But as per type specimen, I find lot of differences until and unless it is highly variable.

Yes sir it variable species at same place i observed lots of variations.

A. pilosa – Creeping or 1-2 ft. high climbing shrub sometimes leaves possess purple veins. Inflorescence subcapitate to capitate, peduncle 3-12cm long. Bracts linear to narrowly oblong.
A. hirsuta – A high climbing shrub. Inflorescence dichotomous cymes (15-22 flowered), peduncle 15-22 cm long. 

yes sir 🙂

To me appears closer to high resolution specimens in GBIF of Argyreia involucrata C.B.Clarke (it lists two varieties herein- inaequalis and involucrata) as below:

This is Argyreia pilosa only (confirmation and replay from Pramod Lawand Ji) Working on Argyreias of India (Kolhapur)
