Thanks David for your reaction, thanks Reka for bringing it through.
I've just uploaded three photo's of my dendrobium on photobucket. The
two that were here on abpo and one taken a day later that shows a side
view of the flower.
So if you would like to take a look and give your 'final' opinion about
it...

Niek,

I'm 99% sure it's D. gracilicaule. Had I not seen the photo in Jones's
latest book I should have said 100%. All the D. adae I have seen or
read about are all white or all cream. Until the above book, I've never
heard of an adae with colouration on the outside of the sepals.

One final check - D. adae is sometimes called the "orange blossom
orchid" because of the beautiful perfume that is especially noticeable
on warm days. D. gracilicaule has little or no perfume.

Also - but this is only a comparative difference - the pseudobulbs of
adae are more slender and wirier than those of gracilicaule, which are
themselves still quite slender.

Regards,
Dave Gillingham
