Cactus blossom and bee~Cactus Monday~053011

I'm not sure about the name of this cactus. I think it was "Peruvian something"...It was on a plaque at the Camelback Resort in Scottsdale. I just didn't get a photo of it. However, it was busy with bees all over it, so I CAREFULLY got close and snapped a couple of photos! Cactus Monday for May 30, 2011.
