Specimen notes from Lo La/Lo La Chu and Sengo Sambu; party movements toward Lilung and Tsangpo
Specimen notes from Lo La/Lo La Chu and Sengo Sambu; party movements toward Lilung and Tsangpo
LSH/1/1/6/1/56 · Part · 1936-06-26
Part of The Ludlow & Sherriff Collection

SUMMARY:
The page lists Primula, Rhododendron, and Lilium/Nomocharis records from Lo La, Lo La Chu, Sengo Sambu, and near Molo, with a note referencing Ludlow specimen 1868 dated 26/06/1936. It records that on May 24 G. Taylor left for Lilung in the Tsangpo Valley after discovering a new race of Yunnan Greenfinch, and the party then split between the Molo area and routes toward Lilung and the Dashong La.

slender in these three primulas, but this I believe does vary in Petiolaris primulas a good deal.

  1. Primula glabra (Genestieriana?) Lo La

  2. Primula lactea (Roylei). P. lactea from this area seem remarkably large flowered. Today I noticed many very dark forms, which had no yellow eye, which I always associated with P. Roylei. Clumps of the no eye one, are fairly common, but the two never mix. Probably there are only under 5% with no eye.

  3. Rhododendron forrestii var. (repens). This has 2 flowers in almost every case (not 1 as expected) & has a loose brown indumentum on leaf upper surface, which may be rubbed off in drying. Lo La

  4. Rhododendron pumilum (Dwarf sp. 2-4"). Lo La

  5. Rhododendron calostrotum (campylogynum). SEED. Lo La near Molo

  6. Rhododendron chaetomallum var. chamaephytum (sp.). Seems to be somewhere near Rhododendron chamaephytum (repens), but has a very large leaf. As very few flowers I did not open any for examination. Sengo Sambu Lo La Chu

  7. Primula Calderiana (Roylei) var. alba. Very few seen. Sengo Sambu Lo La Chu

  8. Primula ioessa. = Ludlow 1868 of 26.6.36. These specimens are only very early ones, but they do not at all resemble P. ioessa type 2514 from Migyitun. Should they not be nearer P. vinosa? Sengo Sambu Lo La Chu

  9. Rhododendron pumilum (fraude?) Sengo Sambu Lo La Chu

  10. Rhododendron lanatum var. luciferum (sp.). Sengo Sambu, Lo La Chu

  11. Seed only of Lilium (Nomocharis) nana and/or Souliei. Both grow together here, from the capsule I can't say which is which. Lo La

No. 17a - Skin set
On May 24. G. Taylor left for Lilung in the Tsangpo Valley where he discovered a new race of the Yunnan Greenfinch.
No. 355 Hypacanthis ambiguus taylori, a form much closer to the Yunnan ambiguus than to the typical race. More & more of the avifauna of S.W. China was forcing itself on our attention.

24th May * Party separates
G.S. remains in Molo area to work the upper reaches of the Langong Chu, Thide La, Lo La, Tsari Sarma passes.
L & T go off to Lilung & down the Tsangpo work the passes in the vicinity of the Dashong La.

They thus separate for the whole of the season & the result is a bigger & more representative collection.

SUMMARY:
Account of a snowy crossing of Lo La to a camp east of the pass, with clear morning weather turning to afternoon rain, steep descent, and heavy snow on the south side. Notes describe scarce but emerging rhododendrons and primulas, highlighted by Primula geraldinae on cliffs, several plant collections, and a sighting of monal by Ludlow.

Lo La, Pachakshiri.

Prim. R. exasperatum 3634, R. lopsangianum 3635, R. sulphureum 3644, R. forrestii var repens 3642, R. hodgsonii 3643.

place, but after going 3 ft. found another two ft. to go, so gave up. And yet it will be in full flower in 60 days. Other flowers are nearly over by then, though covered so deep now with snow. The approx. bearing to our next camp is 150° M.

24th April. Camp E of Lo La. 6 miles. 10500'. Bright clear morning, clouding over by 2.00 pm, some rain about 3-4 pm. Clearing later. Left at 5.30 am, on hard frozen snow, getting up to Pass very easily over snow we could walk on. Reached Pass, 13500', at 6.45 am. Coolies knew the sun would melt the snow & went up almost as quick. Descent on this side, very steep indeed, snow was now getting soft. There is a remarkable amount of snow this side. March tiring through dense fir & rhodo. forest, with deep snow patches till near camp. Rhododendrons coming out, but still scarce. It is grand to be seeing some flowers at last, after such a long pause. The first star turn was probably No 3640 (P. geraldinae), a small but very pretty primula which grows on sheer cliff faces, and at any rate new to us. Some rhodos. too were found. Ludlow saw some monal, which did not appear to be the usual one. But he could not get a shot at one. On the whole a most interesting day, but very tiring. I also saw Prim. Barnardoana, but it is not yet in flower. Many flowers should be out by the time we come back.
