This is a trigeneric cross between Miltonia, Brassia, and Odontoglossum. It has a few mostly white flowers about 12 cm (5") across on a more or less horizontal spike (in this case, though, I've staked it up; looks better IMO and takes up less space). They also have a very nice sweet perfumey scent which I have found is stronger at night, but that might be just me. This is it's first bloom since I bought it in flower in October.
