  1. Prim sp. This has the ring of farina inside the corolla, like the Sikkimensis primulas. It is fairly common in localized places. Colour very green yellow, compared to the yellow of P. Sikkimensis.

  2. P. sp. Differs from 3353 in the colour of the corolla, which lacks the green, and has no ring of farina in the corolla. Growing only 1/2 mile from 3353 in rather similar habitat. Leaves also rather similar.

  3. Prim sp. Appears at first to be a white form of P. 2373(?) which was collected last year on the Kashong La. Could it be a white form of No. 3364 = No 3205? It is growing about 1000 ft higher than 3364, but on open grassy hillside, similar to 3364. It was found in a very big patch, 200 - 300 yds square, where found like this was entirely the white form, with the exception of a very few pale yellow forms. However a few white ones were found among 3367.

  4. Prim sp. Thought at first to be the same as No 2373, taken on the Kashong La, Tibet, last year. It seems to be very near that primula. But may it be No 3364 =

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.
