About 20 years ago my father-in-law gave me a "night-blooming cereus" that had been in the family for many, many years. I believe that it is really the epiphyllum oxypetalum. It hadn't bloomed for about 12 years, but it did last night! I was so excited and took lots of pictures. I just had to share. Here are just a couple. The size of the blossom is about 8 inches across.
