Gentians
Last night I was thinking of the gentians we had seen, and where we had seen them, and it certainly appears that all the creamy ones come from the dry zone, or at any rate the transition zone. Wilkie describes G. amoena as light colored, but sometimes blue all over. As far as I have seen, it is common up here, it is always white or cream in the dry zone, or N. of the main range. We collected it twice S. of the range, in the wet zone, once at the Ma-ha once at Sanden, in each case it was a beautiful rich blue.

Tso Bunang is a curious place. All yesterday the S. lake was in shadow, the E. side was in rain, our camp half in sun with a little rain, and the hill to the N. at the end of the lakes in sun all day.

Tso Bunang Lake Camp
17th August. Halt. Found nothing here. Danong and Tenduk came back from the Tahar La trip. They brought some food stuff.

Among the best were three gentians from the top of the pass.
Swertia handelii G. nankeenis
