Hi Guys....I'm a bit confuse on these three(3)sp of Coe.Earlier on i did post verrucosa of which i thought all this while was mayeriana in my collection.Thanks to u guys for the clarification...So i had looked at Daniel post on mayeriana and i suppose its typical on the one which i tag as pandurata in my collection.....Ok on this post i subbmit a clear photo of all those three(3)sp for us to clarify...which is which...and i hope u guys could assist me on this.....
same two photos
How about we use the same two photos I linked to before for this discussion
Good photo of Coelogyne mayeriana here http://www.orchidspecies.com/coelmayeriana.htm

Pak, at this stage I think your photos above are -
photo 1 - verrucosa
photo 2 - mayeriana
photo 3 - verrucosa but it's a little unclear to tell for sure.
Don't change your labels yet Pak, Wellsy and Bernard or others will be along to give there opinions, I may be wrong.

Coelogyne
It is always difficult to identify species from the section Verrucosae from images shown from different aspects. You could for example, see an image of C.verrucosa from 3 or 4 different angles, and unless you can see the main characters of the lip you can easily be mistaken.
It may help to give a description of the lips from Dudley Claytons excellent book, 'A Synopsis of Coelogyne'.
In my opinion the three images are as follows:
photo 1-verrucosa. Distribution Borneo.
Lip: Mid-lobe irregularly rectangular, claw rectangular with staight margins. 3 keels initially elevated and rounded, lateral keels becoming widened and verrucose.
photo 2-pandurata. Distribution Peninsula Malaya Sumatra and Java.
Lip: Mid-lobe broad, pandurate, bilobed; claw one third to a quarter the length of the lip, verrucose, elevated keels in the form of plates, terminating at the base of the mid-lobe;
a verrucose patch on the mid-lobe.
photo 3-mayeriana. Distribution Peninsular Malaya, Sumatra and Java.
Lip: Mid-lobe semi-elyptic, margins undulate and crenulate, three keels terminating at the middle of the mid-lobe, medium keel slender, scarcely elevated and terminates at the base of the mid-lobe; lateral keels distinctly elevated and verrucose; two verrucose patches from the termination of the keels.
In the final analysis Pak it could well be your own observations that can clarify the identity of your images using the lip descriptions as a guide.

not my bag
Not that anyone should listen to me when it comes to Coelogyne identification mind.....but....I tend to agree with Bernard on these 3 Bill.
From my own limited experience I can reasonably confidently pick photo 1 as being Coelogyne verrucosa. I have grown what I thought was Coelogyne mayeriana in the past. Only to find out much later it was a hybrid. Photo 3 does look like what I know of Coelogyne mayeriana so I will stick with Bernard on that for sure and freely admit to all that Coelogyne pandurata is another I will have to take Bernards advice.
PS: I thought it would be good to have access to a good place to read up on these botanical terms which Bernard has used in his excellent responce....look here for that http://www.orchidspecies.com/glossary.htm
From that source:-
Undulate: having wavy sides
Keel: an obvious ridge that runs longitudinally down the center of a leaf, petiole, bract, petal, sepal or lip

Appreciation
Thanks to u Guys,Bill,Benard & Wellsy.....i suppose i'm abit clear on this now.....but only on photo 3,FYI the plant on photo 3 is actually big n its just like pandurata n also i got it locally from Peninsula Malaysia. What bother me is that we can't get mayeriana in Peninsula Malaysia.....Anyway i wait for it next bloom n for this time i try to post a picture of the flower n the plant together with its measurement....
Thanks again guys,

C.mayeriana has 4-10 flowers which are up to 6.5cm across on a slender rhachis 10-20cm long and C.pandurata has up to 6 fragrant flowers up 7-10cm across on a stout zig-zag rhacis up to 17cm long. Hope this helps
