mastersianum

Well, it finally opened after 2 months from first sign of low bud! The interesting thing is that the pouch is really dark chocolate, not common in this species, which usually range from light rose to pale brown. Petals are light mahogany brown and the dorsal sepal is apple green with white...

I grew this one from a seedling for about 3 years. Still only a single growth, but thankfully that didn't stop it from blooming!
