SUMMARY:
Notes describe travel from Singo Samba along the left bank through fir forest, with crossings of the Lanyong Chu, open yak-grazing areas, and a camp on a slope. Botanical observations include several Primula species in Singo Samba and the Lanyong Chu Valley, with a query about a yellow form from east of Brumban, and mention of a route from Lanyong to an upper bridge.

From Singo Samba, continue up the L bank on aft bearing of 230° for 1 mile; river then bends again to 345°. Path up stream in fir forest, with a few clearings every now and then. Thin cliffs on the right hand side. Fit for yaks grazing.
2675 Continue up valley for 6 miles to pick hub, on L bank. Cross Lanyong Chu at m 1½, return at m 3. Valley has many open spaces, used by yaks as summer grazing ground. Camp on slope. Good. Line of valley approx 260° M.

Primula prenantha. Singo Samba. Very common.

Primula wattii. Lanyong Chu Valley. Growing in great quantity, covering whole swamps. Does the yellow form from E. of Brumban?

Primula wessa. Lanyong Chu Valley. This again is not at all like the type 2514. It seems to be much more like P. nivalis, or like no 2189. (Nipa?). But it is not yet fully out.
-
Primula hookeri. Lanyong Chu Valley. An odd plant. It was low, but on a valley bank, presumably brought down by the stream.
From Lanyong to upper bridge 10 miles, down L bank, the first four miles at the same bearing as
