It could very well be a Cattleya aurantiaca.
Several years ago, this species along with three others was placed in a new genus Guarianthae. So properly it is Guarianthae aurantiaca.
These are all Central American Cattleyas. Cattleyas in the sense of being in the Cattleya Alliance or family.
These can be yellow, orange, on up through a deep red orange color. They rarely open fully. The flowers typically are very cupped, so much so that they self pollinate. That is known as cleistogomous!
Flower clusters range from three or four per inflorescence up to 12-15 on superior clones. In this instance, there is no clonal name or cultivar name.
