Dear Mr Garg
Thanks for checking this.
I have to say that my INITIAL thoughts are that I have my doubts as to the
validity of includingR.nanothamnus under R.giraldii. The latter rose species
certainly has a wide distribution.
Given the 'critical' nature of Rosa in many parts of the world and the
likelihood of its complexities,then how can the authors be certain?
A quick look at the pressed specimens under this name (collected in the early
20th Century in China)do not match well what I understand to be R.nanothamnus
from Kashmir.
Whatever the reality, it is further evidence of the complexity of the genus.
Should we be preparingourselves to be informed that what we thought was
R.macrophylla throughout the Himalaya is in facta different taxon or a number
of different taxa?
I shall post separately about Rosa sericea in the Eastern Himalaya.
This is also further evidence to tell us we must be ALERT to both taxonomic
changes and nomenclatural changesfor ALL genera in the Himalaya! Talk about
"shifting sands"...
Such changes must seem DAUNTING to many members of this group.
PLANT IDENTIFICATION is NOT as quick, easy and straightforward as is widely
believed.

Further on checking, Catalogue of Life shows it as a synonym of Rosa giraldii
Crép. with distribution as China (Gansu, Henan, Hubei, Shaanxi, Shanxi,
Sichuan), C-Asia, Pamir, Alai, Pakistan (Kurram, Chitral, Swat), Pakistani
Kashmir (Baltistan), Jammu & Kashmir (Kashmir)

Having checked in response to an inquiry about Rosa webbiana in Ladakh, I note
thatR.nanothamnus is an accepted name, see: http://www.theplantlist.org/tp
l1.1/record/rjp-15354
I plan to post images I have of a dwarf form of this rose taken in the Kohli
Memorial Botanical Garden - showing delightful pastel pink shades.
I consider this DISTINCT from Rosa webbiana.
