I'd always assumed it was a tigrina - it fits the tigrina images I've seen and I got it with a name... The photo was taken in low light with a flash.
I have a bunch of it but I'm in Australia - if it truly is a tigrina.

Hi, Aus;
The reason I am responding again is that I'm not comfortable in saying from this photo that this plant is all Stanhopea tigrina, and not the X Assidensis or something else, like X Assidensis X S. tigrina. The two reasons for my reluctance to say what it is, either one way or the other are that the ratio of length to width of the hypochil appears large (longer hypochil), and the gap at the apex of epichil, horns, and column stipe cannot clearly be seen in the picture. In both Stanhopea tigrina and S. tigrina var nigroviolacea this gap is quite small, which helps enable pollination by Euglossa viridissima bees. Hybrids I've seen have a larger gap. If you need a picture, I took a shot of the S. tigrina that just bloomed this morning, upward through this gap. I may have in my archives an analagous shot up through S. X Assidensis. I also have some rather odd-looking gap shots of a peloric Stan. tigrina claimed to be nigroviolacea by my friend who sold it to me, and taken up the column gap.
