Nope, they are actually only about two inches apart!
Hello Truemadman,
It seems to me your P. niveum has got an extraordinary big flower, hasn't it?
So far I don't grow P. thaianum but I saw it in flower in a orchid nursery about three weeks ago (Don't know why I didn't purchase it?).
I kept in my memory the flower of P. thaianum compared to a common P. niveum is smaller no doubt - but just a bit not in the way your photo shows.
P. niveum seems in your photo more than twice as big as P. taianum - that's unusual and (I think) gives a wrong impression.
Best regards from Germany, GuRu
