Coment to Notes on the Him. Sax. Dolpo collected by Pete Boardman at Tarap Khola. author A. Young
I agree all resume of this paper.
I would add the S.s. cinerea x S. poluninina garden crossing- paper and
I would add.
I saw S. staintonii and S. micans type herb items. I suppose I sow characters of S. cinerea in these plant.
As I know Bhratang hybrid population S. cin x S. polun. they grow in contact, S. cinerea and hybrida close to S. cinerea grow on the one habitat in crevices of rocks and S. poluniniana and hybrids close to S. poluniniana grow on the second different habitat in river and wet base of vertical rocks.
As I know population from locality over Kagbenii S. cinerea hybrid probably S. poluniniana too(localita is 70 km south of Samargan in the same valley)
and garden hybrid S. cinerea x S. poluninina Isuppose that :
All plants mentioned in this paper (exept clean S. cinerea and S. poluniniana) are probably hybrid plants from hybrid swarm of this two species, ( include S.s. staintonii and micans.)
Some plants S. „polunininana“ collected in nature flower by 2 flowers.
S. cinerea flowered one time only 1 flower too in my garden.
The descriptions of S. stainonii and S. micans are description plants from one hybrid swarm only, no more. Number flower a shape and collor of petals are no significant characters of hybrid swarms.
Only studies on localities Samargang and South of Gurjakhani (do you know where it is, I don ‚t know) can help to solve this botanical problem.
It is possible to solve it only when on loc. Samargang and South of Gurjakhani would found S. cienera , S. poluniniana and hybrids= S.s. staintonii and micans
When it will be not found these Saxifrages there, it exist genetical examination in future only.

Peter Boardman:
Dolpo 1, 2, 3. The seed was collected in the Tarap Gorge some 100k west of Manang. There is a good stream here, as there is almost everywhere in Nepal, but the plants grew on the cliffs above. There was no S cinerea here.
Hope this helps, Pete
I enclose part of Pete information, (I asked him for ecological condition, streams of locality where Dolpo Saxifrages was collected.)
My view on the identification of Dolpo Saxifrages= itis very difficult,
I collected or grow Saxifrages in Himalaya ,I am no able identified them,
althout I try to study hybridisation condition on locality.
It exist many reasons:
The hybrid is possible to identified in case whenhybrid grow with both parents.
This situation is rare or very rare. Hybrids grow offen without parents and contrary,
As Himalaya is rich region they grow more than one, more than two or three species on locality. It is possible to found more time hybridised hybrids (S. andersoii x S. hypostoma x S. quadrifaria)(probably S. andersonii x S. quadrifaria x S. lowndesiii) and next here.
Adrian Young and Tim Roberts plane to describe S. cinerea x S. poluniniana as S. x bratangensis
