SUMMARY:
From Chianang the diarist reports illness among companions, a reconnaissance with Kunio toward Chubumbu La with notable rhododendrons and Nomocharis, persistent rain, and route details. Plans to attempt the Chubumbu La despite local advice are noted, along with Brahminy Ducks near Lanyong; subsequent halts include botanical collecting and bird observations, before proceeding up-valley toward a pass.

...vomiting everything he tried to swallow. He has no strength today at all. I went with Kunio towards Chubumbu La, which is about 6 miles from here, and has not too much snow on it to be crossed. There was nothing to be seen till we reached the head of the valley, then rhododendrons in profusion, P. pauliana all over the place, Nomocharis souliei the best of all, masses of Rhod. aff. repens, in full flower.

3rd June. CAMP CHIANANG. 5 miles. B.P. 189.0° Temp. 50° Time 11:30 am. Ht. approx. 12929'.
Rained most of the night and all today without a stop. Path follows the left bank for 2 miles, then crosses by a foot bridge to right bank. At mile 3 a side valley from the Chubumbu La is reached and crossed. The Chubumbu La lies at a bearing of 162° Magnetic and from here is about 4 miles distant. Follow up this valley left bank for ½ mile, then turn up a side valley. Ascent fairly steep for 1½ miles to a plateau, where there are 3-4 houses, where yaks are grazed in summer. Very swampy ground. We saw nothing at all today, as Lin was not yet too fit and Tsungpen only just able to come up, we did nothing today, but sat in camp and changed flowers. I'm afraid this valley is not as good as I had hoped: we are still too early. So I remain only two days and then go to the Chubumbu La for a day, to see if I can get across. It does not look impossible, though the locals say it is, and will remain so for another 2 months or more, when the Lhopas will come over. There are Brahminy Duck near Lanyong, and I saw they have their young one now and quite big.

4th June. Halt. Chianang. Fine intervals with a little sun up till 12:00 noon, then rain all day. Went up to the South, and had a fairly good day. Rhod. repens is abundant, but not above 14000'. With it were P. harrisii, and P. valentiniana 3953. This must cover the hillside, but is hardly in flower yet. Just as at Tsari Chikchar, it comes just after P. harrisii. First one gets a blue violet hillside, which is then turned into a deep velvety crimson one. P. vernicosa 3951, is here about half blue and half white. Saw a good many Grandala coelicolor above, some rubythroats; the latter is not the Yunnan bird.
Diapensia himalaica 3949, Potentilla leucanota 3950 - Bell common, Pot. stenophylla 3956, Pot. microphylla 3957 & 41, Pedicularis formis 3959.

5th June. Halt Chianang. Rain early at night, but a fine day till 2:00 pm, then thunder and rain and snow on the hills. Cleared 2 hours later. Went up the valley, past two more yak grazing grounds to a pass,

SUMMARY:

Rhododendron 3941 marked with label above camp of 6th. Same place for Nomocharis souliei, marked with stone, also small pink Rhododendron 3925, Rhododendron repens 3942 and Omphalogramma 3970.

X - To Chubumbu La 2 miles ascent. Ascent at first easy on either side of the main stream. This stream is followed more or less to the top. Owing to snow, we did not follow the path, which however exists. Path steep for the last mile, over rocky open hillside. The main valley on the South side flows at a bearing of almost 180°. Descent is steep, but a path appears to go off to the West, which may find an easy way down. Bare hill for 1 mile, then fir forest. Last 2 miles ascent from North are at a bearing of 142° approx.
Chubumbu La

3982. Omphalogramma brachysiphon. This must be the same as 3762. But when that was collected, I noticed all flowers had five lobes. Here again, nearly all are 5 lobed, but there are flowers with 6 lobes. Common from 13,000 - 13,500'.
      Chubumbu La

3983. Primula aff. strumosa. (chionogenes? Chubumbu La) I thought at first I had again found P. hilaris, but this is obviously not that. See 3648, 3754. I do not think this is the same, but cannot compare the specimens now. 3648 was already dropping its flowers when collected, the leaves had hardly appeared. This primula keeps its flowers till the leaves are quite well formed.
      (tsariensis x chionogenes? Chubumbu La)

3984. Primula tsariensis X. These are odd specimens, occurring only here and there, but always among plants of 3983. P. tsariensis from Tsari to here seems very constant. Only one or two plants with white flowers have been seen. (This does not include the Bhutan specimens). But this number

  Explanation of Corke trouble

SUMMARY:
Diary entries at Kula Phu Chu describe persistent rain and wind, difficulties drying collected seeds, and concern for Tsongpen traveling to the Tsanang La amid snow. Seeds of several species were gathered, and after a brief illness, Jill recovered by the 22nd; a sunny 23rd allowed successful drying and collection including Nomocharis souliei.

ripe: some of the beautiful spotted saxifrage and a few other things of less importance. In the Primula marsh I failed to find any Prim. micropetala, and of all the capsules of Prim. littledalei I found, only 5 had any seed in them - fairly ripe. It is raining again this evening, but does not look too bad. Locals say a great many Lopas came over the passes this year. They also say that when the Lopas come, they bring the rain with them - true enough this year anyway. Tsongpen has gone up to the Tsanang La, where he will have a very cold and wet time I'm afraid, he has no tent. We are not used to this very strong wind which has been common for the last few nights. One would think it would drive off the rain, but it does not seem to.

21st September. Kulu Lungma. Rained at night, and all today lightly. The hilltops were all covered with snow this morning, I fear Tsongpen will have a bad time on the Tsanang La. I got a few seeds today, but everything is soaking wet, and I can't think how they are to be dried. There was no sun at all today, and all seeds remain very wet indeed. Jill was her usual bright and lively self all day till after she had her dinner at 2:30 pm. Then she suddenly became ill, and seems pretty bad this evening. She can still wag a tail a little, but is lying without a movement under a blanket with a hot water bottle. I wonder if she has distemper, or whether she got a cold yesterday on Go nyi re. This is the first time I have ever seen her the least bit sick or sorry for herself.

22nd September. Halt. Rained all night and all day. I went up the valley to get seed of a white P. alpicola, and a small lactuca, both of which I found. Besides a Berberis, there was nothing of interest. Opposite camp I got seed of a good coloured Mec. betonicifolia (Mec. betonica 6520). There is very little seed in P. Dickieana capsules, the masses I saw here in July have all been eaten by yaks and ponies. Rather a disappointing day, the rain continues so steadily, that drying these soaked seeds is a very great problem. Jill has completely recovered, her trouble seems to have been no more than a very bad tummy ache.

23rd September. Halt. A fine sunny day thank goodness. All or nearly all of the seeds were dried in the sun. We got very good Nomocharis souliei seed, and some enormous bulbs, the biggest I have ever seen. There was a good deal more snow again last night.

(N. souliei seeds 6518. I collected seeds 6517, P. bellidifolia 6515, Prim. calliantha flower 6524.)
