Thanks Tabish ji for opening up the topic. After sending you confirmed
images of I. bicolor to you last week I was all the time wondering what
would be the plant which was earlier on Flowers of India as I. bicolor. I
think that plant as well as my images Chakrata which I was unsure between
I. amphorata and I. sulcata, and regarding which there were useful feedback
from Wojciech, a well known authority, we can safely say these images
belong to I. davendrae.
Garg ji you can remove ? after I. davendrae regarding my images.
