This my first and only Zigo... it seems to be a Zygopetalum maculatum but I will never know for sure.
This guy has been growing outside under temps between freezing and 45ºC (113 F). This is the first time I can see how it looks like (and smell, really powerful).
Last June 2016 it was like this...
and now it's like this....
Nevermind the multiple plant types in the same pot...it comes from growing outside and I let them stay, at least until repot after blooming.
