Thanks to Mahadeswara ji for link to FOI page.
On FOI page it is mentioned as occurring only above 2000m but Srinagar (Rawathpora) is only 1600 meters asl so the info needs to be corrected.
Am attaching some more photos.
"Madwort spreads well: due to its hooked tips the calyx, which resembles a miniscule maple leaf and envelopes the ripening mericarps, is very adhesive."
Photo 3 shows corolla and a calyx lobe(2mm). Corolla has 1mm lobes and a 1mm corolla tube expanded in the middle. Five pale yellow anthers (not visible in photo) are adnate to and inserted in the corolla tube.
Photo 4 is of tiny round pollen grains (X675). These are the smallest pollen grains I have seen so far in my very limited experience of looking at pollen grains of different plants as a hobby and a pastime.
I wonder if this is a European species which has become invasive just like Conyza canadensis which is so common here that it has even got a vernacular name.
