Dear Dr Kumar
I shall be posting a lot more about Cotoneaster - with many images of other
species but there isNO prospect of EASY identification of either Cotoneaster
or Berberis.
I am NOT keen on most keys. Keys are FREQUENTLY used poorly. Over-reliance on
keys contributesto misidentifications. I shall be explaining more on this
subject in due course. Compiling GOOD keys is VERY difficult and VERY
time-consuming.
Some genera will ALWAYS present challenges identification-wise.
Perhaps, 50-100 years in the future, Himalayan flora MIGHT be better-known,
approaching the level of understanding of British flora (though this is based
upon input over CENTURIES by THOUSANDS ofbotanists - and we have fewer species,
less massive mountains and less difficult terrain to contend with).I will have
long since departed this world.
Even with all this, in the UK we have REFEREES and SPECIALISTS for more
difficult genera incl. Cotoneaster (albeit that almost all Cotoneasters one
comes across in the UK are either cultivated or naturalised).
Indeed there is only 1 native species in the UK - C.integerrimus Medic.
The (now old) 'Flora of the British Isles' listed C.simonsii Baker as
naturalized in many places - this species is native to what was known as the
Khasia Hills (now Meghalaya).

microphyllus from Himachal-GSG24/Sept 2015
Respected Chadwell ji
As all the species considered C. microphyllus has been found to be
misidentified by Cotoneaster expert Prof. Jennette Fryer, it would be desirable
to have key or some descriptions to the species of NW Himalaya. We have to look
for Cotoneaster species from different angles now onwards. Cotoneaster and
Berberis are quite confusing Himalayan genera that need relook and development
of keys for easy identification.
We shall try to photograph Cotoneasters again as suggested by you in different
link.

Anil K. Thakur
