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. Stewartdid 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 tobe 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.macrophyllabut have thought most of the material I have come across or seen
photos of in Ladakh as coming withinRosa 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 DANGERSof always attempting to FIT a plant seen into the
EXISTING species recorded in a region.

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

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
