This very large, almost a tree size Dahlia was shot from near Mussoorie… though no flowers were seen, the leaves and stem made me identify this as a Dahlia sp., can this be Dahlia imperialis as uploaded by …??

Have you checked for Vernonia?. 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.
