Phalaenopsis amboinensis var common

Phalaenopsis amboinensis has two main forms, a yellow and a white (common) form.  The common form has a white background with cinnamon colored bars or blotches.  The particular plant has very dense and dark patches of cinnamon.  It was purchased in one of the orchid shows a few years ago.  I mounted it onto a piece of fern bark and it took quite a long time to get used to its new environment. The plant is now in active growth mode so hopefully i can get a new growth from it.
