I dont know No-Pro-mwa. On both spikes some flowers had extra orange edges and some didnt. I just thought that was par for the course......but going by some of the posts left maybe not......
Your Mini Mark is adorable! I'm jealous, I actually saw one for sale on Ebay that I was soooo tempted to get, when I checked on it later it had already been snapped up! *sniffle* I'll just add it to my wish list!
I've not seen orange flares on the petals before either. I wonder if it's a slight pelorism, where the petals to a greater or lesser degree can mimic the lip. That can happen in some flowers and not others on the same spike, it can also sometimes just be some of the lip colouring going in to the petal.
