Gita, the white Easter Cactus , if it has a name, may be rare. The one called Sirius is rare and sells at Logee's when they have it. I bought one for my daughter years ago and it seldom blooms because she never moves it to a dark spot. It is beautiful plant but unless they get their dark time they will not bloom.
These are Schlumbergera Brazil plants that survived the summer and are blooming again.
