Jungle Cactus [Epiphyllum] Blossom

It's a great time of year, time for our Epis to really start blooming. This one lasts a little longer than one evening so I'm pretty sure it is a hybrid of some sort. In the wild they only bloom for a single night. The blossom is about nine inches at the widest. The cup of petals in the middle is about four across. It is quite an amazing sight and makes for some nice night-time photography.
