I had a look at Jumbo Orchids and did see the photographs in their gallery; I knew that place already, but it is always stunning to see. Mostly how a weird and complicated flower like a Catasetum flower turns something dull and simple when crossed - not always though, clowesetum have gorgeous flowers, too.
But there seems not to be a single picture of Eulobidium.
I'll keep searching from time to time.
