Trigonidium latifolium - what to put it into?

[estación seca]

I got a Trigonidium latifolium in January of this year from Seattle Orchids in a scratch and dent sale. It came in a 3.25" / 8.5cm pot with the newest growth hanging out and up. It has begun new growth from a couple of pseudobulbs. It looks like the rhizomes grow a bit between pseudobulbs, so putting it into a smallish pot is probably not a great idea. Photos I've seen show it growing into a fairly large plant.

Does anybody grow this and have suggestions for how to pot it? I was thinking of a wide, low dish-type pot.

Thanks... There is almost nothing to be found when searching Orchid Board for Trigonidium, so I suspect almost nobody is growing it. If I don't have more information by the weekend I'm going to take it to our orchid society and repot it into a wide shallow container for one of the demonstrations.
