The Zygo I bought last week at the orchid show in Barcelona, has opened three of the four buds it has. I love this flower. I'm no sure if it has a fragrance or not. Will see in the next few days. According to the vendor it's a Zygopetalum x Zygopetalum (does that make sense?).
Maybe something like Zygopetalum x Zygosepalum? (Two slightly different names). Though if the vendor knew that you'd think they'd be able to give you the name of the plant grrrrr
