Many thanks Garg ji.
I am not sure about the difference in phyllaries of the two species. I checked on the internet: In both species, the phyllaries are linear, hairy, and arranged in overlapping rows.
I think we can go with the two features that clearly point to V. indica,
- The flower heads are erect (upright) on slender stalks (and not drooping / nodding on slender stalks)
- The leaf base is stalkless (sessile) with rounded "ears" (auricles) clasping the stem (not narrower, tapering base with very short stalks).
Regards.
