The White Solitary Posts are Poplars , a high altitude tree you will see covering the the entire Landscape of Leh, Ladakh, Jammu & Kashmir, India.
There is a huge and exciting controversy brewing on the scientific name and I have honed onto the scientific name Populus parmirica.
As I have only seen and photographed them during the Winters when not a single leaf adorned them, let alone bear a flower or fruit, it is hard to key on the species with precision for an amateur like me.
I understand these Ghostly white posts have separate male and female trees and are an intricate part of Ladhakhi life.
Willows and Poplars dominate the winter landscape of Ladhakh.
The Ladhaki Frass or Ladakh Poplars or Populus pamirica can be seen only at altitudes above 2000 m.
Leh is at 3800 m and thus home to vast Poplar plantations.
I hope you will help me identify the species in case I have blundered . Am certain the Genus Populus is however correct.
