SUMMARY:
Diary entries describe a difficult march through dense, muddy rhododendron jungle with steep ascents to Pang La (c. 14,000') and a descent to camp near SAWANG, followed by a steep drop to a bridge over the Khoma Chu and an easy ascent along the river to SAWANG. Plant collecting at Pang La yielded few notable finds, and the day was hampered by thick mist; leeches were bad near SAWANG.

(4) 14th August. CAMP NEAR SAWANG. 12 miles. West of Pang La 9000'. Path continues through dense jungle, but ascent easy to m 1 1/2 where ridge is crossed. Thence level for a while through scrub jungle, gradually becoming steeper, with a ridge on the right hand side. At m 3 it becomes steep for a short distance, then easy to m 4 1/2 where there is a cairn. We ploughed our way through mud in dense rhodo jungle for 1500'. Beyond this path is partly over rocks & partly through rhododendron jungle, easy at first then very steep final ascent to Pang La (14000') at m 5 1/2. Descent for 1/2 m easy then pretty steep, with cliff running on right hand side. At m 7 dense jungle is reached, & thence path is very bad & exceedingly steep & muddy through jungle the whole way till it emerges at m 12, the first signs of cultivation are seen. Below is the Khoma Chu, and over it SAWANG. Small camp, water & fuel good & ample. //

(5) 15th August. TO SAWANG. 4 miles. 7700'. Path drops very steeply indeed through dense jungle for 2 miles to bridge over Khoma Chu (6800'). Here the path joins the main road from Lhuentse over the Yeb La. This bridge is very old & not strong. Route then ascends easily along through hot steamy forest R. bank of river to first cultivation at SAWANG. Water & fuel ample: leeches bad. //

Yesterday was about the worst day we've had. We did not have rain till about 3.0 pm when our tents were in, but there was thick mist all day, so we saw no view at all. And there should have been wonderful views from that range. The map is so completely wrong as

SUMMARY:
The writer lists several plant specimens and reports poor botanical results around the Nyang Sang La–Tse La ridge, with Ludlow’s northern reconnaissance similarly unproductive. They decide to move toward a snow mountain west of Nyuri or to Lujuthang, having slaughtered a yak and now needing extra yaks to carry the meat, and note high surrounding peaks and relatively dry conditions.

In July and first half August, there should, one would be flowers all over the place. Flowers there are, but more of the Tibetan type than we want. The Nyang Sang La - Tse La range seems to form more of a barrier than we had expected. It was this ridge which we had expected would make the area so particularly good. Anyway we are wrong. I was out all yesterday, going over the ridge, and a little down the Lohpa side, but there was nothing of any interest at all. Ludlow went up to the North, with the same result. There are Tibetan potentillas, and even some grammopetala, a sure sign that we are in the wrong area. One morning we had a clear hour or two, and saw a snow mountain away to the West of Nyuri, and to there we have now decided to go. It is either there or to Lujuthang, and of the two that seems the more hopeful. We bought a yak up here for Rs 18/- and halaled it yesterday, thinking we should be here for a while. Now we need two extra yaks to carry its meat back with us!

This valley is rather a queer place. At its head are peaks of over 20,000', up to 23,000 odd. I saw some of them yesterday. But they seem not to get a great deal of rain. Yesterday evening we saw an extraordinary sight. The weather in the valley had

SUMMARY:
Observations of abundant gentians and several primulas, noting many flowers not yet open and describing a striking large-flowered yellow primula and a minute blue primula seen in masses. Includes numerous specimen numbers and remarks on flower size and coloration.

Gentiana leucantha sp. nov. 2356. G. phyllocalyx 2357. Meconopsis bella 2358. Aconitum fletcherianum 2360.
Gentiana taylori 2361. G. subfimbriata 2362. Gentiana stevensii 2366. Gentiana pseudophyllocalyx 2367.

This side a thick mist, the other. On the way up saw some gentians coming on, but not open. Also the little white primula we got first between Tama La and Tahtsang (mucronata? 2194). On the other, there is a really fine yellow primula, with enormous flowers 2370. I measured some flowers at 1 5/8" across. They have a darker, orange-yellow centre. We also got more of the minute blue primula 2350, which is very pretty indeed seen in masses.

Gentians abounded, but hardly one fully open, which is no wonder. The finest is 2357 with a very big flower.
