A tree Vernonia (Vernonia shevaroyensis) occur in Eastern Ghats (Yercaud Hills). Though there are no flowers (ray florets in one series) it looks to me as D.imperialis. This species is frequently cultivated as perennial ornamental herb in temperate Uttarakhand. We have a true tree member of Asteraceae which I will upload in the Asteraceae fortnight.
