Actually, this image is very popular on social media, usually with the common name given. Edited - here it is on Facebook, credited to Ejaz Gujjar: Ancient Forests & Champion Trees
Oddly, the Facebook page says nothing about where the Beaucarnea shown is or how big it is. Without such being presented there is no evidence that it is in fact a recognized exceptional example, larger than others known.
The guy who is getting the credit for the photo never gives any info about the photos he posts on his FB page. I didn't actually find this one, have no idea when it would have been posted. He lives in Islamabad, Pakistan, but that doesn't mean the photo is from there.
