SUMMARY:
Notes from Tsarang La on July 18 record several Primula, including P. dryadifolia with a pompom of soft white hairs at the throat, very profuse P. valentiniana, rare P. chamaethauma, and a notable Primula in the nivalis section with withered yellow flowers. P. valentiniana was also seen a few miles west of Langing in early June, and additional taxa are listed.

51a . Tsarang La July 18.
Tsongpen's of our Type Tsarang La
- Primula dryadifolia Sect. From the roots I take this to be a primula in the Dryadifolia Section. But it has a marked pompom of soft white hairs at the throat. Very pretty when seen in close flowering mats on the open hillside.
5866 Primula valentiniana Tsarang La
The furthest West this was seen was a few miles W. of Langing, in the beginning of June, just in flower. It is in full flower here, very profuse indeed.
5867 Primula chamaethauma. Tsarang La
Appears very rare here, only 5 plants being seen. Further West very common. I have not compared it with 5589 or 3893, but the leaves appear very rough in this specimen.
- Primula nivalis Sect. (aff. calliantha Tsarang La sino purpurea ?) Probably the same as No. 5785, the withered flowers of which I took to be yellow. The withered flowers of 5872 also appear yellow. A magnificent primula, very reminiscent of P. obliqua in the way the adaxial lobes are reflexed. Only one specimen seen shows the candelabra effect, with 2 rings of three flowers each. Otherwise 1-, 2-, or 3-flowered, usually 2-. Not common.
