Dear Mana,
I posted on this very topic recently but didn't receive any comments
http://www.dorjeshugden.com/forum/index.php?topic=1424.0A friend on facebook told me that it could be Guru Deva or Denma Gonsa's monastery as he is very active in Kham.
I've been looking for more documentation on this botanist's stay at Shugden Gompa but haven't found any yet. Hope you have better luck than me!
