Which Argyreia ??


Could be A.nervosa. Please post a clear picture of the leaves/ foliage


Could not find a match as per comparative images at Argyreia
I checked all the species listed in the Checklist of Nepal.
I think it is Argyreia roxburghii as per GBIF specimens- one and two.


On further examination, I feel it is more closer to Argyreia nasirii D. F. Austin (syn: A.thomsonii) as per GBIF specimens- onetwothreefour and POWO.
