Caulavola Colmanii = Brassavola nodosa x Caularthron bicornutum
Most people know the B. nodosa pretty well, I posted the Caularthron (formerly Diacrum) parent here last month. This cross was originally made be Sir Jeremiah Colman at the turn of the century. I got it from Hausermann's about 6 years ago. I posted the first bloom pics last year, but this time around is bigger and has more blooms per spike (5 this year, only 3 last year).
