C. Caudebec 'Marty's Orchids'
First blooming for this one. I'm so far behind in repotting that it's still in its original 2" seedling pot, and it's definitely not a minicatt! Poor thing.
The flower should lighten further to a cream background. It's 3.75" wide with a grape/mothball scent.
From Marty's (now owned by someone else?) Orchids.
