Coelogyne Unchained Melody

I have looked at my C cristata and it does not have the markings going up the sides of the lip, as has Unchained Melody. C cristata has the yellow/orange staying right down on the bottom of the lip. Also, unchained Melody has the neater, more erect sepals as seen in the original photo and inherited from it C flaccida parent. Cristata's petals are often more twisted and floppy. The keels are much more distinct in C unchained melody. Therefore, I think your flower is C Unchained Melody!

It should also be remembered that there are many variations of C cristata (Dudley Clayton suggests 13!) plus others that don't quite get a "variety" status but get a name, such as C cristata 'major'. The other parent of C Unchained Melody is C flaccida which is also quite variable and has some named variations such as "Tyabb", "Salmon" etc.

One of the links above shows a C cristata with extremely pale yellow markings. There is a C cristat var Lemoniana (or C citrina) but I think the link is showing C mossiae - which is sometimes sold as C Unchained Melody var alba. I have a C mossiae in bloom at the moment and it looks very similar to C unchained melody in shape and habit but with delicate blooms and the soft lemon colouring. It comes from the same cold areas and is one I highly recommend.

On a slight tangent, some claim that all C intermedia (cristata x massengeana) in Australia should be renamed to C cristata Unchained Melody.

Over the last couple of years I have bought C intermedia and C nitida and they have both turned out to be C unchained melody!

BTW - I find it hard to write unchained melody without the capitals. I notice most people use capitals for it. I know capitals should only be used for people's names and even this is disputable.
