A strenuous climb to the summit of the Kongbo Nga La was welcome descent on the far side.
There is a lot of larch on both sides of the pass. The biggest trees are of peculiar shape. They have quite thick trunks for 20-30 ft & then suddenly taper to a point.
Rho. vellereum 3600 on Kongbo Nga La.

SUMMARY:
Field observations around Kyimpu noting numerous flowering plants and seed collections, including Roscoea alpina, Deutzia hookeriana, Stellera chamaejasme, and Meconopsis bella. A supposed crane’s eggs find proved to be partridge; later, the party halted with rain, bought a sheep, and walked toward the Le La. The locals are described as friendly.

Kyimpu July 3. Roscoea alpina 2275. Onosma hookeri 2276, Stellera chamaejasme 2277 (113
Deutzia hookeriana 2279, Pedic. longiflora var tubiformis 2282, Mec. bella 2283

...a crane's eggs, but when he brought them, they turned out only to be those of a partridge, a great disappointment. There were four in the nest, of which he broke one.

A good many flowers on the way up, lots of the Primula jeffreyana 2257, of walshii 2256 just below Kyimpu 2258. Also of the Incarvillea lutea 2252 of which I took some of last year's seeds, which appear to be good. P. atrodentata is in seed too, of which I took a lot of that. Mec. bella 2283 is in flower here, others up here. There is a nice little Deutzia hookeriana 2279 in the rocky gorge between the two bridges, which is both fragrant and pretty. And the Stellera 2277 is a nice little thing, looking prettiest when it is half out—red in the centre of the buds, contrasting with white of the open corolla all around. I think we should do well up here. The locals are all a friendly lot for anything as far as I can see.

4th July. Halt. More or less fine till 1130, then heavy rain most of the day. Bought a sheep for Rs 3/-. We all went up towards the Le La, turning off right before reaching it. P. hyacinthina 2294 is very common.

SUMMARY:
Field notes list several Primula specimens with remarks on identification and variability, including doubt about P. hopeana subsp. pudibunda and variable P. aff. dryadifolia in S.E. Tibet. Localities noted include Younger-la and Miri-la (mid-August) and Kyabden on the Nyang Chu, where P. petrocharis (walshii) lacked flowers; additional records at Kyabden include Cyananthus, Gentiana, Habenaria, and Neottianthe species.

CONTENT:

6125. Primula capitata subsp. crispata. Fairly common. Rather a poor form.

6126. Primula hopeana? subsp. pudibunda. I doubt if this is the true P. Hopeana.

6127. Primula aff. dryadifolia. Seems very variable in S.E. Tibet, the scapes varying in length & sometimes bearing only one flower, sometimes 2 or 3.

6128. Primula aff. macrocarpa. Younger-la 23 Aug. - Miri-la - Aug 15. Same probably as 6061. See note under that number.

6129. Primula petrocharis (walshii). Kyabden, Nyang Chu 23 Aug. Common here, but no flowers & seed all brown.

6130. Primula littledalei.

Kyabden Aug 23.
Cyananthus hookeri 6179
Gentiana paludosa 6181
Habenaria diceras 6182, Neottianthe calcicola 6183

Gent. callicops 6189

SUMMARY:
A stony valley leading west then north ends in a small lake below a retreating glacier, with steep, crumbling hills and few flowers. The party adds a dwarf primula (possibly Primula walshii) to their tally and compares finds with previous primulas; they travel 8 miles to Thampe with a fine morning and heavy rain in the evening.

the West, then turned out of that to the north. Like all valleys here it was full of stones and boulders. It finished at about 15,500 or 16,000' in a lake 600 yds long and 200 yds wide, beyond which was a retreating glacier. The hills all round are crumbling to bits, very steep, and don't look much good for flowers. However we brought our primula total up to 39 with a dwarf one - perhaps Primula walshii - very little of which we saw, No. 3413.
P. concinna 3413 (1937)
On the way back we found a lovely primula, very like a small edition of P. obtusifolia collected yesterday.
P. caveana 3410 (1936)
This is almost certainly P. caveana, No. 3410.
P. tenuiloba 3417 (1933-34)
Flower rather smaller, a little redder, and more farina on leaves, both surfaces, bracts, calyx and pedicels.

11th July. Thampe. 8 miles. Fine for an hour or two in the morning. Rain very heavy in evening, with strong wind. Nothing new to be seen, though we
