Brassia hybrid
 

It is a lovely cross. The blooms are long lasting and emit fragrance.

This is a really nice one, with wide petals and sepals. It also has good color and spots.

Brassias remind me of dinosaur jungles. (I know, there were no flowering plants around when dinosaurs trod the planet.) They have flowers that remind me of lizards or prehistoric spiders. They have huge prehistoric-looking pseudobulbs, and contribute that trait to their hybrids.
