I am beginning a check on Cotoneasters posted on this site.  Unfortunately, I suspect a majority are misidentified.  Will be sending available images to Jeanette Fryer (on a CD she does not use e-mail).  She was co-author with the late Bertil Hylmo of 'Cotoneasters' (2009) - the most knowledgeable person on the genus.  She is always busy with other identification tasks so will certainly take weeks perhaps months before we hear but worth the wait.

 

Please note her comments: "Klotz included within C.microphyllus a number of taxa from a wide area ranging from W.Himalaya, Kumaon, through to eastern Tibet and the provinces of Yunnan & Sichuan but in its strictest sense C.microphyllus has only been recorded from Nepal.  More research is desperately needed."

 

I hope her determinations (accurate identifications) will encourage members to take a greater interest in this neglected genus, photographing more species.   There is every possibility of locating species new to science within this genus.

 

It makes sense, when those with specialist knowledge are available to name material to take full advantage.  The present situation with the naming of Cotoneaters in Indian herbaria is in need of improvement.  Many specimens are very old and/or in poor condition, of a scrappy nature in the first place.

Jeanette Fryer has named this as Cotoneaster marginatus Lindley ex Loudon Series Microphylii NOT C.microphyllus - which as other posts have indicated is, strictly speaking, only recorded from Nepal.

C.marginatus has been recorded from H.P., Uttarakhand and Nepal.

Dear Mr. Chadwell,

Thanks for getting the correct identity of the species in my post.

As suggested, I'll try to click more photographs of this group in my future forays in its habitat.

Regards,

Gurinder

Dear Dr Goraya

Good.  It will be most help (and much-needed) to have more images of as many taxa of Cotoneaster

as can be located both in flower and fruit.   Such contributions will help towards a better understanding of

the genus in the Himalaya.   Such input is especially important with 'difficult' genera.

Please follow my guide-lines being sure to include images of STERILE shoots as well.  This is not something

one would automatically think of doing.

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.

Dear Dr Kumar

I shall be posting a lot more about Cotoneaster - with many images of other species but there is

NO 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 contributes

to 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 of

botanists - 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).

Best Wishes,

Chris Chadwell
