I acquired this as T disciflora, but I don't think so. This bloomed while I was out of town, so the pics of the flower are likely past prime. The defining characteristic of disciflora is a disc-shaped lip, which mine does not display. Also, disciflora is spotted; mine has subtle stipes with no evidence of spots. The plant habit is like that of Trias picta, maybe a bit larger. The flower, though, is enormous compared to other Trias species in my collection. It is 1.5 cm at its broadest, and 4 cm with the dorsal petal taped open. The first pic is how the flower presents itself naturally (past prime), and the second two are with the dorsal taped up. Pics are not the best, as I whipped them out to see if I can get an ID before the flower completely croaks. Ideas?
