Apparently Rsc. is an error in the OrchidWiz awards section. It should be Rlc. Yen Corona (I'll change it in my previous post). The name used to be Blc. Yen Corona and many growers will probably continue to use that name, it means that it's a cross between a Brassavola, a Laelia, and a Cattleya. But the orchid world has recently changed the name of one of the orchids in it's background from Brassavola digbyana to Rhyncholaelia digbyana. That makes it a cross between a Rhyncholaedia, a Laelia and a Cattleya which is abbreviated Rlc.. So the most recent name for that orchid is Rlc. Yen Corona 'Green Genie' but the older name is Blc. Yen Corona 'Green Genie'. Sorry for all the confusion.
