I do have some images of Geranium pratense taken in the UK earlier this year which it might be worthwhile me posting for comparison purposes - accepting that Nasir recognised subspecies stewartianum.
Let me try to explain. In the Notes Yeo supplied me, he draws attention to the problematical G.collinum-pratense-himalayense alliance. He considered this was particularly critical in the NW Himalaya with high quality pressed specimens needed (nowadays these can be supplemented and sometimes replaced by high quality digital images (provided the advice given below is followed). This alliance has pink to blue flowers (sometimes white) in which the stamen-tip and stigmas are never blackish-purple...
I consider it will be helpful for keen photographers, willing to make an
additional effort, to know which parts of Geranium to photograph.
Having images of such parts of each geranium will greatly aid identification
and enhance our understanding of the genus in the Himalaya - and perhaps you
can help with the locating and identification of a species new-to-science!
PHOTOGRAPHING GERANIUMS:
IF only the first one or two flowers have come out don't bother to collect as the form of inflorescence will not be evident.
The rootstock is important; get enough to show
whether compact or creeping, or annual. You can photograph the base of
the plant which should provide this information. Clearly, one requires
permission from the authorities to uproot a plant. There is still a need and indeed role for the collection of
pressed specimens for herbaria in India but that is primarily the domain of
staff of botanic gardens/ institutions.
In the early stages of flowering look out for
the best-developed unripe fruits available.
If fruit is ripe try to include both dehisced
and undehisced states.
If the fruits are falling with the seeds
inside them, collect some (many geraniums disperse their seed explosively but
some seed is often retained).
Include some loose petals when
pressing (detach if necessary). Expose stamens to show filament shape and
hairs by taking 2 or 3 sepals off a flower from which petals have recently dropped.
Smoothing out one or two leaves and
flowers as you close the press may be helpful; a few separately pressed basal
and lower/middle stem leaves are often useful.
Wilted specimens can be very
misleading.
Notes should be taken as to flower
posture, colour and patterning of petals, colour of stigmas, anthers and distal
parts of filaments (not necessary if your photos show these).
And don't forget to ensure the
stipules are clearly shown - something that would have been obviously in
pressed specimens, so not mentioned above by Yeo.

A species very similar in appearance to G. wallichianum but very easily differentiated by very narrow linear stipules, 5-7 lobed leaves more deeply divided, each segment narrower, narrowest towards tip and gradually broader towards base with 6-13 acutish lobes, and narrowed suddenly below the lowest pairs of lobes. the species is now considerd closer to G. himalense but latter has smaller leaves, broader segments with lobes concentrated in upper with 5-7 lobes, mostly lobed again.Flora of Pakistan considers Himalayan form as subsp. stewartianum, but this taxon is not accepted in light of variation within the species.

I have been able to procure Image of holotype as well as original publication of G. kashmirianum. An interesting observation in publication sent in Dec. 1984, authors had thanked Prof. Yeo for going through the specimens and seems gave go ahead as new species, before he published his own G. clarkei in 1985.I have ordered Hardy Geraniums by Dr. Yeo. It will reach me in a week, enabling me to comment conclusively. In the meantime if we have only one Geranium from G. pratense complex (leaving aside G. himalayanum) in Kashmir, what was need for new names, why not upgrade G. pratense subsp. stewartianum (already published) to species level. Perhaps I will have answer from Yeo's Book.
