I am in agreement that this rose approaches Rosa macrophylla.   Clearly, some forms of Rosa webbiana and some xerophytic forms of
R.macrophylla are difficult to tell apart.

Thanks & regards to one and all.

I have gone through different comments posted by the authors. As flower colour appears white in the centre and presence of many number of red rose hips and its size the species resemble to Rosa webbiana only. However I am unable to confirm it with my present available records. Rosa macrophylla is not very common in Ladakh and reported in the lower altitudes only but Rosa webbiana is abundantly found in Nubra, Suru (Kargil) and Leh valleys upto higher reaches.  Rosa webbiana is also reported with dropping prickly branched bush while R. macrophylla is tall shrub with long thorn. I am also agree with Chris Chadwell Ji that R. webbiana and high altitude forms of R. macrophylla can not be easily distinguished and only with pictures it is more difficult.

Thanks
Basant

Thanks for your input Basant.

Dickore & Klimes (2005) do not list Rosa macrophylla from Ladakh.   They list R.webbiana, tuschetica,
oxyodon, multiflora.   The latter, I understand to be a double pink introduced from China or Japan.  Stewart
did not list either R.oxyodon or R.tuschetica.

What about Rosa oxyodon - which pressed specimens of and some of the photos available on the internet (
bearing in mind they may or may not be correctly identified) are close to the form of what I understand to
be R.macrophylla?   Need to look into this further.

Have any other group members heard of Rosa oxyodon in Ladakh?

Much the same applies to Rosa tuschetica.....   These roses are known from such places as Georgia.

I have seen material above Khoksar in Lahoul that I HAD considered to be within R.macrophylla
but have thought most of the material I have come across or seen photos of in Ladakh as coming within
Rosa webbiana.

It would be informative if we were able to obtain the thoughts of a Rosa specialist as to how 'critical'
or not the genus is in the Himalaya?

ASSUMING that the identifications of R.oxyodon and R.tuschetica are correct will be an example the DANGERS
of always attempting to FIT a plant seen into the EXISTING species recorded in a region.


Best Wishes,


Chris Chadwell

After perusing all threads in efi site, I feel it is more closer to images at Rosa webbiana Wall. ex Royle rather than those at Rosa macrophylla
