It was good indeed that you posted different 'populations' separately as this is a different species as well.

According to Jeanette Fryer whilst this is part of the MICROPHYLLI Section, it is NOT Cotoneaster microphyllus.  It is C.marginatus Lindley ex Loudon which is also new to eFI.

This species has been recorded from H.P., Uttarakhand and Nepal.  According to Fryer & Hylmo, it was introduced into cultivation in 1838.  Often hybridizing with other diploid species, it can produce very variable off spring, some of which have previously been attributed to other species.  It caused much confusion before its diploid nature was realised. C.marginatus is vigorous growing, often forming a dense mass of branches which project from the shrub in all directions.  The abundant fruit are slow-ripening and hence are not taken by birds until well into winter.

Respred Chadwell ji
Thank you for all your efforts in bringing the real identity of my postings on Cotoneaster species from H.P.
This species has not been recorded in the Flora of Himachal Pradesh, although, Flora of Himachal Pradesh includes 24 species. It is quite possible that it might have been mixed with C. microphallus and some similar looking species.
I don not have access to the scholarly work of Jennette on "Cotoneasters: A Comprehensive Guide to Shrubs for Flowers, Fruit, and Foliage". So, I am not able to differentiate between these three populations photographed at 3 three different localities. I have one more photograph of this plant from lower altitude as well. I'll try to post that one also when the time permits.
It will be very nice of you, if you could kindly post the species description of my my postings as per new IDs. This will be useful for me as well as others to identify these very difficult to identify plants.

Regards
Anil Thakur

Thanks a lot, Chadwell ji

Dear Dr Thakur

Could you give me the full reference for 'Flora of Himachal Pradesh' with exact

name, authors and year of publication? 

There is still a long way to go in studying the Cotoneasters of the Himalaya.

I consider it acceptable to comment upon and use short extracts from sources

such as floras but for copyright and other reasons, I am not in a position to

copy and send FULL descriptions of species from the Fryer & Hylmo book.

Since we currently have access (through me) to the services of Jeanette Fryer,

the way forward is to take many more images of ALL Cotoneasters encountered,

so a comprehensive and reliable set of images is available on the eFI data-base.

These can be sent for her to DETERMINE.  Whilst we have access to someone with specialist

knowledge of the genus, then let us TAKE FULL ADVANTAGE.   Rather than spend (and probably

waste) time ATEMPTING to name material ourselves.  As you will realise, some specimens can

be tough to name with confidence, even for those with specialist knowledge.

Kindly follow my advice (see: https://groups.google.com/forum/#!topic/indiantreepix/vD9SHWdzVds)

- being sure to photograph sterile shoots as well, which is not an obvious thing to do.

Best Wishes,

Chris Chadwell

Respected Chadwell ji
Flora of Himachal Pradesh has been compiled by bH.J. Chowdhery and
B.M. Wadhwa from BSI in 1984. Although, it includes most of the plants
from H.P. lying in various herbaria of India, it lacks detailed
descriptions of species. It includes only one or two line descriptions
of plants and does not help in proper species identification.

Respected Chris Chadwell ji
As far as various Floras of H.P. are concerned, C.marginatus Lindley
ex Loudon is new species for the Flora of H.P.

This season, I'll try to collect more information on this genus from H.P.
But, it will be difficult for me to differentiate between different
species, unless I have some of their differentiating features. Kindly
give some extracts or keys to the Cotoneaster species from NW
Himalaya.

Regards
ANIL THAKUR
