Swertia tetragona? ABSEP2016/31 : 6 posts by 3 authors. 9 images.

This is another beautiful Swertia which looks plain white from a distance but faint lines on petals along with hairy pale marks (two stretched ovals at the base of each petal) are visible on a closer look. A quick look on FOI suggests S. tetragona. Please advise.
