(Identified by the description of Flora of presidency of Bombay) 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: https://www.gbif.org/species/3678879 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: Argyeia pilosa wight & arn (Convolvulaceae) : 5 posts by 3 authors. Attachments (7) 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 https://sites.google.com/site/efloraofindia/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: https://api.gbif.org/v1/image/unsafe/http%3A%2F%2Fmediaphoto.mnhn.fr%2Fmedia%2F1441366491260W0xlaPPd0e1VxGLu This is Argyreia pilosa only (confirmation and replay from Pramod Lawand Ji) Working on Argyreias of India (Kolhapur) References: The Plant List Ver.1.1 (Unresolved) India Biodiversity Portal IBIS Flora Flora of Davanagere District, Karnataka, India By B.
