Stellamizutaara genetic makeup

[Meg25]

Hi, I posted a question to anyone who knew about the catt. hybrid Stellamizutaara 'kelly lea", since I was having no luck finding out much about it. Several of you were very helpful and informed my of it's genetic make up.
It is nearly ready to open one bud, and since I am excicted to see what it looks like I made a drawing of it's make up, to compare to it's actual flower looks like when it blooms.

Here is the drawing with it's information:
Stmla. kelly lea is a cross of Brassavola nodosa x cattletonia 'keith roth', and ctna 'keith roth' is a cross of Cattley bicolor (50%) x broughtonia sanguinea 50%. I read that those contribute equally.

Some interesting notes about Catt. bicolor "... not often seen in hybridizing". An entry for Broughtonia sanguinea said " used in breeding for it's shape and colors, it's often crossed with others for petal substance."
The Catt. bicolor is noted for it's heavy long lasting flowers.

The plant's leaves and growth clearly show it's brassavola influence, it's tag notes that it blooms every 5 months or so, each time a new one leaved growth matures. This is the plant:

I find the genetics of orchids one of the most interesting things about them, and I like to go backwards to see it's genetic contributers when a hybrid flowers. ( of course some are so complex it seems impossible...I'm talking to You bulldog Paphs...) Thanks to everyone for their help, I will post a pic then the flower opens. Hopefully it wont be long!
