I received this in low spike October 29 of this year. It is SVO8095 Catasetum (Ctsm.) Sweet Adaline (Ctsm. Louise Clarke 'Wonder Woman' x Ctsm. Dagny 'Fantastica'). The flowers opened this weekend while I was out of town. There is no scent today, but it has been in shade for the afternoon.
There are two, three-inch / 7.62cm flowers. They point in opposite directions so they cannot be in the photo at the same time. The background is white with a substantial green suffusion. The upper sepals fold down over the flower so it is cupped, rather than flat. It will be interesting to see whether this changes in future years.
Edit: This doesn't look anything like the very few Sweet Adaline photos I found. I have a message out to Fred.
