Coelogyne ovalis

Coelogyne ovalis Lindl., Edwards's Bot. Reg. 24(Misc.): 91 (1838).

Distribution: China, Assam, Nepal, Myanmar, Thailand, Vietnam

A vigorous species which is easy to grow. It has relatively small flowers but the plant will form a huge specimen given half a chance.

WOW

A wonderful detailed lip on your species image.

appreciate the detail

Not many people would say that about these really (wow)...the flowers are quite small and sparse really.

You have to look close to appreciate the detail in them.

Thanks Bernard.

Grow it big

This needs to be grown into a huge speciman say 500 bulbs to really show its potential.

bit sunburn't

Yes Ian....I agree....I've never counted them but I have such a plant I think.

It's a bit sunburn't right now but it'll survive an probably flower its guts out soon.

Coelogyne

Since our ongoing discussions on Horst's submission, (node 6958) I have been taking a closer look at C.ovalis. I believe the species above is not C.ovalis, but C.pallens. The lips of these 2 species are entirely different. Information regarding my ID is found in Dudley Claytons book (page 261)on this genus. When looking on the internet, one finds that C.pallens is presented entirely differently.
Hope this helps to the overall discussions.

bernabu

just noticed

I just noticed this last commment here Bernard. Must have become buried at the time.

Are you still of this opinion?

Regards wellsy

more on this

photos

on the basis of these two you have posted links to Warren (thanks for the links) then the photo I have posted is Coelogyne ovalis.

I'm still interested to hear Bernards comments when he sees this post next I think.

Coelogyne ovalis

Steve, the only reference and image I have to this species is in Dudley Claytons book
'The Genus Coelogyne' A synopsis. In association with The Royal Botanic Gardens, Kew.

His description of the lip of this species is as follows:
Lip saccate (with a conspicuous hollow swelling) at the base, 3-lobed, side-lobes erect, partly around the column, oblong to triangular, lower part of margin cilliate, mid-lobe ovate, tip rounded, mucronate, margin cilliate, callus of three keels at base of lip, two extending to near tip of mid-lobe, initially close together, diverging the converging, undulate, median keel indistinct. Column arcuate,1.5 cm long, expanding to form a hood 0.7cm across near the tip , tip rounded , notched at each side.

The image of this species in his book is at variance with the image posted here.
Of course the image could be incorrect, others who have this book, may perhaps confirm my observations.

digest

Thanks for posting that.

I'll digest this description and post again once I have compared it with some other photos Bernard.

Regards wellsy

I can't see a difference.

Coelogyne pallens is a synonym of Coelogyne fimbriata

As more images of Coelogyne fimbriata and Coelogine ovalis I check out, as more I get confused.
From the images I can find on the web, I can't see a difference which justify to have 2 species.
This doesn't mean that in my opinion it should be one species only. I just can't find a difference.
Unless we find an expert for Coelogyne's or we find reliable descriptions for both species, it will be difficult to get to a conclusion.

look here

Coelogyne

Horst makes a good point regards the likeness and difficulties when trying to identify these species.

Dudley Claytons book on this Genus was published in 2002. In this book he shows 9 species placed in Section Fuliginosae. They are:

1)C.fimbriata, 2)C.chrysotropis, 3)C.padangensis, 4)C.longeciliata, 5).C.pallens, 6)C.triplicatula, 7)C.arunachalensis, 8)C.ovalis and 9)C. fuliginosa. Out of these 9 species he shows 6 images.

These images are numbered in order as shown in the book and from above, as follows:
1). 9). 8). 3). 5). 6).

Three of the above numbered species have become synonyms to number 1).C.fimbriatum, they are, 3). 5). 9). which all look similar to C.fimbriatum.

Following the above logical sequence, and looking at the images of the other two species, which are very clearly not the species shown in this post, I can only say that
your image is C.fimbriata.

Hope that this helps.

Coelogyne ovalis versus fimbriata.

Unfortunately I don't have Dudley Claytons book. I have to take different images as references.
Taking a look at the link Warren mentioned above from the orchidspecies website which is a image from Milan and as clear and sharp as it better can't be and compare it with the image of Coelogyne ovalis from the same website, I can see that the column is different. C. fimbriata has a kind of a brim placed over the column, while C. ovalis doesn't have it.
The side lobes of C. fimbriata are more fringed than on C.ovalis.
The dorsal sepal is bend forward on C. ovalis, but not on C. fimbriata.

On Steve's plant we can not see the detail with the column. His images are taken from a different angle. But the side lobes are less fringed, similar to C. ovalis and the dorsal petal is bend forward similar to C. ovalis.

Using this two images from the orchidspecies website for comparison only, my vote goes to C. ovalis.

Ones again, taking different approaches with different images, we get different results. What is right and what is wrong? I don't know.
Maybe the real difference from one species to the other is to find in a different blooming season, a different flower stem, different pseudobulb shapes, different leaf shape etc.

Coelogyne

I am showing the Key to the species: C.fimbriata and C.ovalis in Section Fuliginosae in D.Claytons book which has been mentioned previously.

C.fimbriata, psuedobulbs 2.4-4cm long, ovoid to ellipsoid. (Inflorescence with slender and erect peduncle). Lip mid-lobe orbicular, fimbriate, callus of three keels, median keel virtually a brown nerve, lateral keels terminating at the tip of the mid-lobe. Sepals and petals pale yellow-green, lip whitish or pale yellow marked with brown.

C.ovalis, Lip mid-lobe ovate, rounded, mucrinate tip; margins fimbriate, with three keels. median keel indistinct, lateral keels terminating near the tip of the mid-lobe, undulate. (Flowers pale yellowish-green, lip marked brown, keels darker.
